Subject: Yanking the Tires
Out from Under Us

Imperialists-
I had a rather unsettling conversation with Firestone today. I have been attempting to
obtain a set of 721 P235-75 R15 wide whitewalls for one of the Lincolns. It is a nice
looking tire with a 1 1/2" whitewall, and is the original sidewall design for the
1975 Cadillac.
The web site shows the tire to still be available, but I can't find them in L.A. So I
called the service number and was advised that the tire is on back order with no
production date. The very nice person on the line advised that while the tire has not been
discontinued as yet, and she admitted that it was one of the most popular 721's ever, that
this is usually the preliminary step to discontinuance. Aargh.
Does anyone know of an acceptable substitute tire (same size, with 1 1/4 to 1 1/2 inch
whitewall? Or, is there a way to contact Firestone and show them that they are missing a
collector car market here?
I would like to hear any suggestions.
Jeff
I may be confused, but I recall the Firestone 721 as being one of the worst radials ever
produced.
If I'm not mistaken, they were eventually recalled after a long battle w/ the government
and a piece on "60 Minutes".
My mother's 77 Charger came new w/ Firestones that I think were 721s. Handled like s--t,
NO traction in the rain. A set of Goodyear custom polysteels (discontinued) straightened
it right out.

I recently switched from 721s to Michelin XH4s on my '65 Crown, and here's why:
Basically, the 721s are awful tires. In the two years or so I had them on, my car would
never ever track straight despite three alignments, the handling was sloppy, and they made
excessive road noise due to the design of the shoulder blocks. Finally, one of them
suffered a belt separation. I was almost relieved.
I (briefly) considered replacing the two fronts with new 721s, and had a passing notion of
buying a new set. One of the alignment shops I use (same location since 1935) refused to
call the 721 a tire at all. In fact, he had warned me when I put them on my Imperial that
this car would destroy them in no time due to its weight. He was correct. The only nice
thing I can say about the 721 is that the tread held up pretty well.
(The 721s are indeed being discontinued by Firestone. I forget the name of the new tire; I
guess I'm not interested!)
I went to Discount Tire and priced the XH4s and some Bridgestones on the recommendation of
the alignment guy. I chose the XH4s because everybody has such high praise for them, and
the price difference is really not that much more than the Bridgestones or 721s.
The difference these tires make has amazed me. They are silent, the handling is crisp, and
on the Interstate I can read nearly an entire chapter of War and Peace before my car
wanders from its lane. The only drawback to these tires is the narrow whitewall; but do
you know what? I can get used to that. They still look nice, and I can't see them when I'm
driving anyway.
One other factor in my choice that may not apply to you: my Firestone dealer sucks
(although they had 721s in stock), and the Discount dealer is excellent. Since they are
both chains, this may not be your experience.

Hello Ron, Tony and IMLers,
I vaguely remember a story like this happening in the 70s, but the tire in question was
the Firestone 500. My friend's dad had a set of these defective tires mounted on yet
another defective product, the Ford Pinto. (Remember these cars would explode when struck
from the rear.) Talk about a winning combination!
To the IML...
I haven't tried this myself, but I know a couple of guys that have found tire shops (or
tire men) that can shave the tire to widen the white wall a bit. A friend in New York did
this to brand new radials on his '61 Plymouth. He had the ribbon white wall shaved to
around 2 inches, and the tires look like pretty authentic wide white wall tires from that
era (except for the radial bulge). It has now been several years and many miles, and the
tires still function and look great.
I've talked to several tire men about his procedure, and they have all said that it should
NOT affect the structural integrity of the tire. The problem seems to be finding someone
to do it. I have found a referral for a "tire-shaver" here in San Jose, but
haven't tried him out yet.
Is there anybody out there that has had this done, or that is familiar with he process?
Stephen
Hi Jeff,
Good to see you at the West Coast Meet. You may already have this information, but I'll
relay it anyway in case anybody else needs it. BF Goodrich is still selling a P235-75 R15
tire with a what looks like a 1-1/2 whitewall (I didn't measure it myself). Bill Lister
had a new set on his (used to be yours) '66 Colony Park Wagon. Bill said he special
ordered the tires from Wheelworks in Los Gatos. The tires looked pretty good to me, and I
think I'm going to order a set for my '63 Convertible.

All of these from a regional Goodyear/Goodrich/Cooper dealer (Big 10 Tires). How they got

haven't noticed anything but improvement since these were installed).

Howdy,
Thanks for the warm welcome. I have already found the list a great tool for learning about
my terrific vehicle. To continue, I have a few questions:
What is the conversion for the near-bald L78-15 tires I have?
[go to the web-page - Tips & Resources - Your Car's Components - Tires - Tony]
And finally, the spare tire appears to be the original, it looks good but is it safe to
use if I have to?
Thanks Again.
An area car aficionado tells me to get new radials and I will not have the problem
anymore. He saw I was riding on Firestones and became even more adamant in his advice.
I run Firestone 721 radials with the inch-and-a-half whitewall on my 1967 Crown and they
look, handle and ride very nice. Of course they're not the correct original 9.15x15 US
Royals with the three-ring whitewall (wide-narrow-wide, unlike Lincoln and Cadillac), but
they work.
A friend runs the Lincoln-style bias-ply tires with the narrow-wide-narrow whitewall in
the stock size (9.15x15) and loves them, but I'm sold on radials.
BTW, the 721 has been discontinued except for one model and size: the one we want! Ask
your Firestone dealer or Tire Station or other tire store. They should run around
$75/tire.
Also, I know Elijah's had good luck with Michelins, so you might consider them as well!
-Chris H
Interesting thing about this radial discussion. Back in the good old days, we had a '67
(Crown 4-door) and it needed new tires (probably around '70...), and when we took the car
in the dealer told us not to install radials - said the car wasn't built for them and that
the handling would be compromised, etc. We even went to the Chrysler dealership and he
confirmed it!
Does anybody remember anything like this?
Likewise, I had heard the grumble over the "old" 721's...and then had a tread
separation on the '65 F75 at rather high speed (like 90)...the tire store I use and trust
installed two new tires..I thought they would be the same BFGs that were on the car...
surprise they were "new" 721's...2000 miles later it still rides like the liner
it is in a calm sea despite the MS heat and heaving roadways.
Bias ply tires...Ole Blue ('69 Elec) still rides on tires my father bought in '73..and
every trip gets harder to bear (and to steer)...the plies shift position more often than a
MS congressman eating diner with a Baptist preacher at Disneyland!
George
As a kid in the early '70s, I remember hearing this discussion when my grandmother went in
to get new tires on her '71 Imperial. The Chrysler dealership guy who sold her the car was
pretty convinced that radials would more or less destroy the front end, would be
impossible to align correctly, and would just generally be a disaster.
However, my '71 Imperial has about 216,000 miles on it right now, and it had radials on it
when I bought the car with 131,000 miles. I've had the front end rebuilt, but only due to
twenty some odd years of carrying around a huge cast iron block and all the accessories --
in other words, the normal wear and tear. The car has perfect alignment, and what I
consider to be excellent handling.
And for those who haven't heard it before, I'll make my plug for Michelin radials. Both
grandmother and myself have gotten a lot of mileage out of the Michelin X, XH, and XH4
series radials. I tried a set of Goodyear Tiempos on my Imperial, but it wore the tread
off all four tires in about 25,000 miles -- the car was just too heavy for the tires. The
Michelins are the only things we have found which give any kind of tread mileage on an
Imperial -- but I don't think we ever tried the Firestones, so I can't speak there.
Grandmother has also had very good luck with Cooper tires on her '78 New Yorkers, and they
are less expensive than the Michelins.

Regarding Radials
When radial tires first became available to the mass-market in the late-sixties and early
seventies, large car owners were advised not to run radials on their cars. It seems early
radials were not up to the weights and forces exerted by cars the size of Imperials.
I think one of the few tire manufacturers to make radials at the time for full-size cars
was Pirelli. My mother bought a set for her 1970 Plymouth Sport Fury GT. She remembers
that when the radials were installed, the car steered so smoothly it had the sensation of
driving on ice. However, her enthusiasm for this first set of radials waned when, cruising
at speed just outside of Atlanta on a hot summer day, all four radials suddenly threw
their treads.
It was while arguing with Pirelli (I hope I am spelling that correctly) about these tires,
that the unhappy early relationship between big cars and radials was discovered. I don't
know how or if the issue was ever resolved.
Now, however, I run all-season radials on all my large Chrysler Products, and have had the
best experience with Michelin tires.
My worst set of tires was from Sears. While driving home from the Cars & Parts meeting
in Springfield, the sidewall of the right front tire failed. Were the car any thing less
than an Imperial, I'm sure there would have been an accident. As it was, I wasn't sure
anything was wrong until I detected a slight starboard list and a far away sound. Stopping
and opening the door, I could hear the scream of escaping air while the tire deflated into
a useless mound.
The only thing I don't like about the radials is that I cannot get the original style
white-walls Imperial used.
My 2-cents.
George:
Bias ply tires...Ole Blue ('69 Elec) still rides on tires my father bought in '73..and

Thanks for the info on the 721s (yes, they did update the model but not the name/number),
but what are you doing driving around on 25-year-old tires on your Buick! I pulled out the
bias-ply spare on my 72 Charger (it wasn't even the original spare) and it was too brittle
and cracked looking, more so on the inside sidewall, to even consider as a spare. Yikes!
-Chris H
remember the early skepticism which greeted the arrival of radial tires many years ago .
It was probably fueled by a combination of some technical truths coupled with a good dose
of the NIH (not invented here) syndrome. Today, however, I have no hesitation about
running any of my cars, old or new, on radials.
For my 64, they have made an unbelievable change for the better in terms of handling and
especially tracking .They have been on the car since 1989 ( about 13,000 miles ) and have
been entirely trouble free and, as near as I can tell, not caused any compromise to the
mechanical componentry of the front end. Norm
I've got a set of Sears "specials" on my 73. Although the price was very good
and I thought I was getting a decent size (235/75r15), once they were installed I saw
several major differences between them and my bald Goodyears. For one, although they were
inflated to 35 psi, from the condition of the sidewall it looked more like 15 or so. I
checked the load range of the tires beforehand, and they were 1300 lbs apiece which should
have been plenty for my car. I also noticed that although they were the same size as my
Goodyears, the actual tread was significantly smaller. When you hear people talk about how
2 identically sized tires can actually be different widths depending on how the
manufacture measures the sidewall to tread section width, they aren't kidding! I'll be
keeping a close eye on this set until they wear out, which considering how many miles a
year I drive this car will mean they will rot first. On cars like ours I would recommend a
235/70r15 if possible, but no smaller than a 235/75r15 from a name brand manufacturer.
Dan Dale
Hi Chris and All,
I agree regarding the 721s. I have them on my '64 and the car handles and rides like a
dream. Cruising on the freeway is a much more comfortable and relaxing experience with
radials.
Jay Weinert, Imperialboy
One further point about Radial Tires, if we haven't beaten this subject to death:
Radial sidewalls are constructed to be more compliant to lateral stresses, (that is why
they look under-inflated to someone used to looking at Bias ply tires). This means that
when a sideways force is placed on the car, the body will move quite easily for the first
1/2 inch or so. If the whole car has identical tires, the driver feels nothing, but if the
radials are mixed with bias ply tires, and the radials are on the back, the car feels
"twitchy", since when he starts into a turn, the back end of the car flops to
the outside of the turn in the initial instant of steering input. To a driver who is not
used to this, it feels like the car is starting to come around, and he will correct for
it, which will make it "twitch" the other way. This often leads to a "solo
spinout", which we have frequently on the local Freeways.
Unequal tire pressures and mixing tire brands/models can also cause this feeling.
The only way to fly is to buy 4 identical good quality radials, inflate them all to the
same pressure (this will contradict what it says in our older car owner's manuals), and
the pressure should be at least 30 PSI.
You will be rewarded with a much more stable feeling high speed ride, considerably (like
5%) better fuel mileage, and incredibly long wear. I have gotten over 100,000 Miles out of
Michelins on 3 different cars.
Dick (ex-recap plant tire prep guy) Benjamin
Here's my two cents. I have a 54 New Yorker that came with 8.20X15 originally. I replaced
them with P235 75 15XL 721's from firestone. They have a slightly under two inch
whitewall, and an extra load sidewall. I like to drive my car a lot, and these tries look
great and ride great too. I was concerned of mushiness when I first got them, but the
dealer assured me that I would like them, he was right. I would definitely recommend a
heavy duty sidewall. Our Imperials are heavy haulers.
I have the same tires on my 63 LeBaron. Again, I really like the look and ride. Dad has
the same tires on his 65 Crown Coupe and our 68 Crown Coupe. We really like the ride and
appearance. The tire is a good tire and it is reasonably priced. I think the last set I
bought was about $80 per copy, mounted and balanced. If you are a stickler for
originality, then go with the bias ply tires. I will sail past you on the freeway with a
smile on my face, while you are frowning and battling the ruts.

Hello all,
Please lend a hand in suggesting a tire worthy of carrying around my '72 Imperial.
I heard Michelins are good. Any feedback on this and what model?
Thank you,
Paul Riggi
Michelin makes an excellent tire that would be good for your 72 Imperial. The model of
Michelin is "XH" which is an extremely durable, long lasting tire. They do make
the 235R X 75 15 inch tire which is comparable to L78 x 15. I have purchased this make of
tire and found it to be long lasting and very quiet. The tread pattern will not have the
problem of catching the grooves in pavement that other tires do.
Paul,
Michelin XH Radials, size P235 75 R 15. My family has run these for years on our Imperials
and New Yorkers, with excellent results. The current set on my '71 Imperial have been on
the car for five years and 50,000+ miles, and still look great with plenty of tread life.
Michelins also have stronger sidewalls, which yields improved cornering and stability,
important qualities for an Imperialistic ride!
Elijah
We have a set of Sears Michelins ("Roadhandlers") on our 81 Olds Delta 88
Royale. They have about 60,000 miles on them and have plenty of tread left. They are
quiet, ride well, handle well, track straight, and are good in the rain. What more could
one want? :)
I just bought 5 tires for my 1969 Imperial this last weekend. Didn't even consider
anything but Michelins, but decided to get "real" ones this time, not Sears
models. The current "top-line" Michelin for cars like ours is the MXV4
"RainForce". I am very happy with them so far, but of course it's kinda soon to
tell. :) I have absolutely no doubt they will prove to be great, long-lasting tires. The
other Michelin model mentioned to you (XH4) is still available and is somewhat cheaper
than the MXV4. Pays your money and takes your choice. :) I'm sure that if you choose any
model Michelin appropriate for our cars you will be very pleased.
Hope this helps.

Well, it appears I've broken down and decided to actually buy another Imperial, rather
than just look at them.
This is a '71 LeBaron coupe owned by George Merrick in Oregon. The question I have is, can
anyone suggest a good tire for this vehicle?
It has bias-belted tires on it now that I will keep for posterity and/or display, but I am
looking for a good safe road tire right now that has a correct "profile" to it
("shoulders" like a bias-belt).
Way back when people were talking about Firestone 721s, but that was for older Imperials,
I believe. What would be good for a '71?
Mark
With over 300,000+ miles experience on two '71 Imperials, I can wholeheartedly recommend
the Michelin XH4 radials -- use P 235 75 R 15. Yes, they will cost you a bit more, but
they will LAST, and you'll get improved ride and handling due to Michelin's stronger side
walls as well.
Elijah
BTW, I assume these Michelins are whitewalls?
Yes, the Michelins are indeed whitewalls. Someone a while back inquired about the width of
the whitewalls, and I haven't had a chance to measure them yet. The original tires had a
two-ring whitewall (large inner, small outer) -- you can see it at
http://library.gcsu.edu/~elijah/imperial/71Promo.jpg
And actually, I'm up to THREE '71 Imperials now! One of them is my midnight blue
former-daily-driver (now enjoying a relaxing semi-retirement, and getting exercise on a
regular basis), another was formerly my Grandmother's and is in storage, and the third is
a parts car, recently purchased.
I tend to be a purist and want my cars to look correct. I've heard all the stories about
how poorly bias ply tires perform and am not totally convinced that radials are so much
better. Granted radials do perform better, but I do not believe it is as significant as
long as the bias ply tires are new. Quite often, when hearing bias ply horror stories, it
turns out that the tires were put on the car when it was restored 10 years ago and have
hardly been used so they are very hard and nearly square from setting up so long.
I agree with that - though the arguments I have heard on the IML in favor of radials are
persuasive and come from respectable sources.
However, recently I got to drive a '69 Imperial with bias-belted tires, and I have to say,
I expected to notice a big difference but I didn't.
The owner of the car kept warning me that the tires didn't feel good, that they were okay
when they "warmed up," but you could feel every bump in the road and a car with
bias-belt tires will jerk you around with every little change in the road surface, etc.
Then I drove the car and I thought: what is the problem? I could detect none of the
problems he had warned me about, and I drove at many different speeds on many different
road surfaces.
And I am one of those "Princess & the Pea" types - in case no one has ever
heard that story, it's about a lady who sleeps on a stack of mattresses and complains that
she can't sleep because there is a single pea at the bottom of the stack.
In other words, I am VERY picky and notice tiny defects in just about anything. But the
bias-belted tires were fine with me. You could tell they weren't radials; it seemed they
were a bit noisier (?) and had a slight tendency to be more effected by changes in the
road surface - but nothing objectionable or impossible to handle.
I suppose one experience at moderate speeds in a car I'm unfamiliar with is not a reliable
indicator (I guess the only way to know would be to drive the SAME car with two different
sets of tires). But my point is: bias-belted are not as horrible as some would have you
believe.
And they do "look" right, which is important to me (but then, you can find
radials that have a similar profile, too).
Mark
I am contemplating buying wide whitewall tires for my 61 Custom Coupe. Question #1:
I am aware of Coker tires but wondered if there was any other company that IML'ers have
used that are better? Question #2: What was the ballpark width of whitewall in that year?
Question #3: I have heard past debates on bias vs. radial. Are radials OK to get that
won't throw off the driveability of the car? Thank you in advance, Mike Blythe.
Michael & Nancy Blythe
Mike, I have generally run bias ply www tires on anything I own that had them when new. I
tend to be a purist and want my cars to look correct. I have always dealt with Coker and
have never had a problem with them. I have always found them to be very helpful and they
have all info on what tires are correct for each car. I've heard all the stories about how
poorly bias ply tires perform and am not totally convinced that radials are so much
better. Granted radials do perform better, but I do not believe it is as significant as
long as the bias ply tires are new. Quite often, when hearing bias ply horror stories, it

hardly been used so they are very hard and nearly square from setting up so long.
John -- 67 LeBaron (radials) 61 Lincoln (bias ply WWW's)
Good Radials will be a big improvement in high speed ride, safety and handling. By good, I
mean Michelins -accept no substitute! Unfortunately, there ARE NO really "good"
wide white tires, including the new radial wide whites sold by Coker and others. All the
wide white tires I am aware of are basically very cheaply built tires that are made for
show only.
Of the wide whites I have bought, the only satisfactory service I have gotten are
Firestones, which I bought through Stan Lucas Tire, in Long Beach California. Most likely
Coker handles these too.
But they are not radials, and they are not "good" tires, just barely acceptable
for a show car.
The old wives tale that older cars do not handle properly with radial tires was never
true, it was based on the prohibition about mixing radial with bias ply on the same car
(which IS important). I have used radials exclusively on my daily drivers since the early
70's, on cars as old as my 48 Land Cruiser (Studebaker, not TOYOTA!). They handle and ride
just fine at normal road speed, with a tad more roughness coming through from rough
pavement at speeds below about 40 MPH, when compared to Bias ply tires.
I would guess the original white wall width for a 61 would have been around 2 inches, but
others will be sharper on this subject than I. I'd say anything 2" or wider would
look right on your car.

Question #2: I have heard past debates on bias vs. radial. Are radials OK to get that

Bogus!! Radials are superior. That's why we don't really have "glass" tires
anymore.
I have 235/75/15's on my '48 Dodge and they work very well. I would never put a set of
bias tires back on the old girl.
Kne.
I believe both Firestone and general make a wider whitewall in a radial, I have had them
on my Cad for the last 6 years, They look great and handle well
I also saw articles in 1973 Motor Trend about the 1973 Monte Carlo, with "Radial
Tuned Suspension" where the suspension geometry has different camber adjustments.
Yes - this is where I got this, too. At one time, Camaro's and probably other cars had a
little badge on them that said "RTS" - this was back when radials were just
coming out - and it was pushed like it was a big deal or something.
Of course, this could just be marketing BS, but having read so many articles about how
complex tire & suspension design is, and how the engineers of cars work
with/collaborate with tire engineers, I thought their might be something to it.
Mark
Carmine--- The only times I have heard that a 1960's car should not have radials was when
I met a guy at school years ago that had a 196? mustang. He put radials on it and he said
they were wearing funny because the front end geometry of his 'stang was made for bias
ply. I also saw articles in 1973 Motor trend about the 1973 Monte Carlo, with "Radial
Tuned Suspension" where the suspension geometry has different camber adjustments.
I don't know really, the oldest car I owned was a 1973 Nova and the manual said that it
could take radials or bias.
Gregg
The front end alignment specs are usually slightly different for radials. The most common
difference is a reduction in toe-in. This is not a big deal, but to be accurate, I should
have mentioned this.
Dick Benjamin
Hi all, This talk of radials reminds me that ever since '64, when my father picked up his
new Imperial (which he did every two years), his first stop would be the Michelin shop to
install radials...... I remember as a kid, other drivers would go out of their way to let
us know that our tires were dangerously low, to the point of waving us over on the
highway, at which point my father would politely thank them and tell them we had
'radials'... I can still see the confused look of that concerned driver, as this new
Imperial with 'low' tires zoomed off down the road.....
Manhattan Jack 81 Imperial
I think the extra money for the Michelins is well worth it! That is exactly what I have on
my 68, and after 12 years they are still perfect in all respects, no sign of age cracking,
smooth and quiet. The 235R70's are going to look rather low and wide on that car, I think
235R75's are a better choice (almost an inch taller, same width).
Dick Benjamin
Dear Jack,
I put Michelins on my '71 on the recommendation of the list and I'm happy with them.
However, my '68 has tires with the name "Arizonian II" on them, in P235 75R15,
and I've been quite happy with them. I do not know how much they cost because they were
put on by the previous owner, who got them in - guess where? - Arizona, but I am sure they
are cheaper than the Michelins, and they are holding up well. They are whitewalls with a
good width on the whitewall (almost the same as the originals), and have a correct looking
"profile."
These tires are probably some other manufacturer's economy line, and may be sold in
different areas under different names. I'd be curious to know if anybody else has ever
heard of them.
In the meantime, if you can find some steel belted radial Arizonian IIs, I'd recommend
them for your '68.
Mark
I agree, Dick. The thinking in tires has changed since 1968. In '68, the look was
"tall and narrow" (relatively narrow). The R75s seem better for the '68.
I also try to find a tire that has a distinct "shoulder" to it - don't know if
that's the right term. If you cut it in half, it has a sharper "edges" on it - a
flat top with a pronounced drop-off toward the sidewalls. This, to me, approximates the
look of the bias-belted tires that came with the car and keep it looking
"correct." Modern radials are far more rounded in appearance, with lower
sidewalls and don't always look right on older cars.
I also agree with you, tires are one place not to skimp. Even if you only put low mileage
on your cars, they're worth it for the peace of mind.
But I would still feel okay recommending the Arizonians, though I'm sure they're probably
not as good as Michelins.
Just my opinion, Mark M
Hi all, I'm getting ready to buy tires for my 68 Crown. I know a couple months ago that
all were talking about what good tires to buy. I went to BJ's and found Michelin XW4 to be
$95. installed. This is $20.00 better than Sears. But that's a lot of money for 5 tires
for on a car that I might drive 3000 miles a year. They will dry rot before I show any
wear. There are a lot of tires that are $60 to $70 that I think will do. BJ's also has
B.F.Goodrich and Uniroyal all for a lot less, I can save $120.00 by going this way. I
don't care for Uniroyal much, but would like to know if anyone has the Goodrich's, and how
do you like them? Any other input would be good also. Montgomery Wards had General's on
sale for $50.00 too. I plan to use P235/70R15, is this good?
Thanks Jack R. Shultz cookie115@msn.com
On the tires I have run 235/75 and 235/70, I have to say the 235/70's look the best. BFG'S
AND Firestones are good-excellent tires. Ran them for years no problems.

Jack- just a few thoughts about tires- off-brand tires are made (for the most part) by
name brand manufacturers- look at the side wall - there is a set of numbers and letters on
all tires that are indicators of quality and service life- traction, wear index #(the
higher the better) load range, temperature. 70 series tires are shorter than 75 series
tires for the same given width (aspect ratio) look on your drivers door post- there should
be a sticker which indicates the proper size of the original tires- your tire dealer will
have a chart- which converts the "68 size to modern size. if you use a tire taller or
shorter than stock it may upset your speedo calibration. Finally- if you drive your car
infrequently you may wish to invest in a set of tire covers to protect your tires from the
ravages of solar radiation and UV rays.
When Michelin graced the world with a radial it was a tire that did not give or flex like
the bias ply tire of the time (which was good). It lasted much longer and improved
the handling on almost any car (which was also good). Many manufacturers were afraid
that because the tire didn't absorb the shock of the road that it would be transferred to
the suspension/steering components of the car (and I can guess that the makers of the
OTHER tires might have pointed this out). Hence ignorance or bad info made the radial a
evil demon to cars not "built" to handle them. I've run radials on every car I
own (save Ol'Blue who will be next) which includes kingpin MG's and a '55 Buick, and
haven't noticed anything except improvement (and if you can improve the ride and handling
of a '65 Fleetwood 75 Sedan that's saying something). If nothing else they don't
"flat spot" as much when you don't drive a car as often.
If your suspension is in good working order (Bushings intact et al) I'd say go with a
radial..they have been designed for softer ride since the X1. If your suspensions
questionable shame on you!

I bought Michelins for my '68 at Sam's club. The ride and handling have been great and the
set of 4 came to just under $400. And that included new valve stems, balancing and Sam's
includes a road hazard warrantee and lifetime rotation/balance. I thought that was a
pretty good deal!
Michelins seem to work well on the '68.
Happy motoring,
Dale
OK, you all convinced me, I'm getting the Michelins. Thanks for all the help and info. I'm
going for the P235/75R, The higher tires will look better.

Imperialists-
If you'd like to be 100% correct and original, you'll want to buy 8.20 x 15 tires with a 2
1/2" wide whitewall. It's a high-bias tire, which means it has tall sidewalls and a
rather narrow tread. The whitewall comes to about the center of the sidewall, and the
outer sidewall is ribbed. They're available from Coker as BF Goodrich or Firestone.
I put the BF Goodrich tires on my 1959 Crown Southampton and was delighted with the 100%
correct appearance, as well as the ride.
Remember that the wide whitewall was becoming less fashionable in this time period, and
therefore narrower. 1962 would see the 1" on Imperials. A 4" would be totally
inappropriate, and even the 3" will look very wide because of the different bias of
the L78-15 tire.
If you choose to put the L78-15 on your car, it will be more of the square-bias tires of
the mid sixties (actually pioneered on the 1964 Lincoln). The sidewall will be shorter and
the tread wider than the original. This may reduce the ride height by 1" or more
compared to original, so it may not be a good idea if your car is already low.

good current tires to use - Michelin, Firestone, Sears. But get the catalog - a picture is

PS I bought tubes from Coker a few years ago to fit the 5.50x16 Pirelli tires on the
sports car car I'm restoring - these tires are probably 40+ years old and are only on the
car so it can be aligned & pushed around while work is being done. The tires have been
inside, outside, near freezing and in 120+ temps - but hardly any sidewall cracking -
what's the deal?!

As to low profile tires: the sidewall is significantly shorter, which, in a tire properly
sized to the wheel provides less sidewall flex and better handling. Yes, the tradeoff is
in a jarring ride. I look to the "police" versions to provide the best
combination of ride and handling (yeah, I been known to drive over a few curbs; something
you daren't try with a low profile tire). But I'm more willing to put up with stiff shocks
(KYBs) than I am willing to put up with wallowing. To each his own.

We keep going over and over this subject. Just figure out the dimensions for yourself. The
first number is the width in Millimeters "255" is 255 mm, or about 10". I
don't know what year your car is, but chances are these tires will be at least 1" and
maybe almost 2" wider. You'll have to look to see if you have clearance, between the
fender skirt and the rear wheel, and between the frame and the inside of the front tire in
a sharp turn.
Remember when you hit a bump in a turn, the tire will move a little closer to the frame.
The second number is the percentage relation between the height from the rim to the road
as compared to the width. "70" means the tire is 70% as high as it is wide, or 7
inches from rim to tread (with no load on the tire). This will be a short, fat looking
tire for your car, when the original was a tall thin dude. Some like this new look, some
don't. You pick it.

least on cars from the late 60's onward.
I do not believe radials will "harm" your suspension. I think older suspensions
were designed with the tires that were available at that time in mind - when radials came

accommodate the new type of tire. And in fact they used to advertise that ("Radial

Well, as Col. Bat Guano would say, you'll have to answer to the people of Dallas for that
remark!
Seriously, I'm fascinated by this - by how people's perceptions are formed and how they
get changed. I remember in the late 60's, when radials were becoming more well known, that
people at first said they didn't want those things on their cars because they didn't ride
well.
I believe this may be in part because radials were generally found on imports at first,
and imports, being smaller, with firmer suspensions, had a rougher, harsher ride than big
American cars - a quality which people attributed to the tires, or at least associated
that kind of ride with those tires.
Or maybe radials back then were substantially different than radials sold today. I wish
there was a tire engineer on this list . . .
At any rate, I agree, modern radials on an Imperial are fine.

I've been battling with the same bias vs. radial dilemma with my 57 Imperial. Most of the
people I've spoken to with late fifties cars (imperials and otherwise) have told me that
radials are the way to go, a few have said that it really makes no difference in handling,
but I doubt that. Usually, the first thing a fellow car owner will say to me is, "Why
the hell don't you get radials for that thing?" It's usually a big topic of
conversation with my car because it has triple-stripe Sears bias tires on it now, which
are hideous and draws a lot of attention from those who know cars. I have a feeling I'm
going to put radials on it, because I figure the handling can only get better, and that is
a HUGE problem right now. The farthest I drive it is about 2 hours to shows, which isn't
much, but I'd prefer to keep the car on the road during that 2 hrs. Keep me posted on what
you decide to do.

There must have been a few old wives working at Chrysler in the late 60s/early 70s, 'cause
this is the tale they tell in my 1971 Owner's Manual:
"RADIAL PLY TIRES
Your vehicle is designed for cross bias and bias-belted tires of the sizes indicated. The
use of radial ply tires is not recommended because of their very harsh ride at low speeds
and possible unfamiliar stability characteristics. Should these tires be desired, the
maximum allowable size should be selected. Radial ply tires should always be used in sets
of five and under no circumstances should they be used on the front only."
Again, I'm not advocating this position. I'm just saying this was once a widely held
perception, and may have contained some small kernel of truth in it. However, I think what
has happened is that the design of radials has progressed a bit since 1971, and the
"very harsh ride at low speeds" statement probably no longer holds true with a
modern tire.

wheel covers spinning on rims, I tried several remedies but could not stop the movement. I
put metal valve stems bolted through wheel to hold things in place. Rear wheel covers
never moved, front wheel covers moved to rear never moved, only fronts would move.
Apparently, the turning of the front wheels with radials would somehow create the
movement.
Another factor not mentioned so far is the correct look. For what it is worth, you just
can't get the right look for a fifties, early sixties wide whitewall out of a radial. The
taller stance of the bias ply tires and the look of the whitewall is unmatched. These cars
drive well with bias ply tires, but any weakness in suspension and steering components
will be more noticeable than with radials.
I generally draw the radial conversion line somewhere in the mid-sixties. Any of my
earlier cars will properly maintained steering/suspension components and correct wide
white wall bias ply tires.

In a recent post the statement was made:

Unless someone can explain to me how radials can damage a steel rim,
While I am no expert, I recall the following statements that were made, when this subject
came up previously:
Radial tires cause the rims to flex more than bias ply tires. The additional flexing can
cause damage to older rims designed for non radial ply tires. In particular, vintage wire
wheels designed for bias ply should not be used with radial tires as the radials can crack
the vintage rim.
Additionally the additional flexing of the rims by the radial tires can increase the
likelihood of losing the wheels hubcaps (a problem that I have experienced).
A suggested solution was to buy new rims. Ford pickup 15" rims interchange with most
year Imperials that use the 15" rim.
"Pep Boys" and others sell these rims at a reasonable price.
For what it is worth....

OK here is the definitive statement on my experience w/ 15" wheels on MY '59
Southampton- Yes I owned and drove this car for several years, yes it had stock 15"
wheels which were interchangeable w/Phord pick up trucks. Yes I did mount second hand
Michelins on the car. One night my college roommate and I liberated a full length beveled
glass mirror from a 1920's house that was being torn down on Classen Blvd. in Oklahoma
City. Yes an OKC cop saw us back out of the driveway as he was going the opposite
direction down Classen and did a u-turn at the light. I floored my 59 (with radials) and
took off for the nearest side street we careened back and forth and finally killed the
lights and pulled into a dark driveway and lost the cop who was in a Plymouth or Dodge
interceptor.
I lost no hubcaps no valve stems no tie rod ends ball joints or torsion bars. The wheels
never cracked warped or groaned, my roommate lost something but That is another story.
Exner put 14's on the 57 to lower its profile and center of gravity. '59 saw the return of
the 15" wheel for the Imperial. The radials stayed on the Imperial until it was hit
by the Idiot in the '54 phord custom who broadsided me.

There is no "rough ride". Radial ply tires are in fact more flexible at the
sidewall than bias ply tires. If you are committed to attending shows, scoring points and
trailering your car to them as a pure collector, go for the originality of bias ply. If
not, don't listen to anyone who tells you there are severe trade-offs to radials. The
trade-offs are so slight, in my humble but very high mileage opinion, as to be more than
offset by the advantages of newer technology, smoother ride and safety that comes with a
good set of radials. The difference in handling is astounding and you can buy a nice set
of Michelins ( there is no other tire) 235 75 R 15 for about $ 95 each.

Having listened to the varying opinions of the group, and doing some pricing from some

Crown. A company in South Carolina called Diamond Back Classics has 235/75R15 tires
manufactured by Dayton for $126 each, far less than Coker's Goodrich Silverstone Radials
at $179 each. Both of these have 2-3/4" to 3" wide whitewalls. I would prefer a
Michelin, and certainly at $95 each, but appearance is as important as everything else.
The car now has roughly 1" wide whites, and it looks, well, underdressed. Coker lists
the Michelin at substantially more than $95, and indicates the whitewall is only 1".
Does Michelin make a wide whitewall radial, because I haven't found anyone around northern
Virginia who has anything wider? I've never heard of Dayton, but the Diamond Back guy said
they'd been in business since 1915. Has anyone in the group heard of Dayton, and know of

Dear Neal,
I would look into these tires from Diamond Back a little closer. Another Dayton dealer is:
http://www.altonstire.com/tires.htm
I would contact this dealer and ask if he can order wide whites from Dayton. If he tells
you Dayton doesn't make them, then Diamond Back is possibly offering you a custom
"shaved" tire.
At Barrett Jackson I saw a tire being shaved. This is where a whitewall tire is put on a
lathe-like device and the thin layer of black rubber is shaved off revealing the white
below. In this manner 1" whitewalls can become 3" whitewalls. If that is what
Diamond Back is doing, I would think long and hard. Putting aside the resulting texture of
the shaved portion of the whitewall, I'm not sure I would want a shaved tire on a 5000 lb.
car. And regardless of what Diamond Back tells you, I would contact the Dayton factory
directly to verify they are manufacturing wide white radials before I purchased them. And
if they ARE making these tires, they should be available from other dealers. Pays to shop.
But when all is said and done I would call Coker and buy the correct 8:20x15 bias plys.
They are even a few $$$ cheaper than the Daytons. My 2 cents.

66 Convertible (with a good set of Michelins that mask a certain vagueness in the original

66 LeBaron (with Firestone FT70 radials and a totally rebuilt front end for very precise
handling.)
(They are apparently a subsidiary of Bridgestone/Firestone.)

Yes, they are. The original Bias-ply tires have a much higher, stiffer profile than the
radials. The radials are more rounded, making a flatter, less "formal"
appearance, and much more flexible.
But what about the rumors that the rims are not made for radial tires? Is it true that

Big load of hog-wash. Get a set of radials if you have any intention of driving the car
regularly. Dick Benjamin suggested the following to me, and it's good advice -- for
touring, get a set of Michelin radials. If you're going to show the car, get an extra set
of rims and mount the correct bias-ply tires. Interchange them when you need to.
Maybe I'll get the front end checked out to see if that's part of the problem, too...
DEFINITELY. Get the whole suspension looked over, rear too. My '60 had shot springs in
back, and needed all new shocks, plus new tires. Now that everything has been replaced,
the handling is incredible, and that's without a new front end, which I'll probably do
next. Take care of the car and it'll take care of you.
Case in point, took that car out for it's first long distance trip last weekend. Took the
Taconic highway, which is a very narrow-laned, old road that winds through the Catskill
mountains from New York City into Albany and points upstate. It was Friday night and it
was raining. Huge puddles. The car stayed right where it was supposed to, even though the
conditions were hydroplane-ulous. At one point the car actually began to glide across some
water in a deep turn -- the new Michelins held the road perfectly, and I never lost
control of the car, even though I could feel the glide. It was both remarkable and a
relief -- I had two kids in the car plus my wife and her best friend.
Get radials for driving, and get the entire suspension checked out.

with putting bias belted tires on your car, if that's what you want. It just comes down to

All the advice on DRIVING radials and maybe showing correct bias is good. I wouldn't drive
around the block on a set of new bias if I had access to a decent set of used Michelins.
Of course, a set of new ones is the best solution and believe me, you'll not be sorry. I
first got my father convinced on radials for his 66NY back in about 72..He had to go over
the Cascade Mts the next am early, and as it happened there was a fresh dump of snow...he
was amazed at the traction as well as quietness...less road noise transmitted thru unibody
and unbelievable cornering over what he already thought was great. I agree with whoever it
was that said about Michelins 'is there any other tire?'
My 67 Crown Cpe doesn't have 'em yet, but she runs decent radials now as is. I just snuck
her out a couple weeks ago to blow out the cobwebs (expired tags & no brake
lights...tsk-tsk on me!). We are on a delightfully windy country road.
On the only little straightaway we briefly saw 80...my 9 yr old daughter saw it too and

if he knows about the IML. I can't imagine that he wouldn't. He really has a museum and

One little thing of special note on my 67: The original quad piston front calipers have
been replaced with the newer style such as on the 69-70's type single piston. I don't know
as yet what required changing as far as the steering knuckles or steering arms, but a swap

Subject: IML: Tire Questions and answers, really long and opinionated read
No problem, Rob. Most of these discussions have stirred up some controversy, so ;you have
to be aware that what I spout off with is really just my opinion, and others on the list
have lots of experience too.
I have tried various tires over the years and in my college days, I earned my keep at a
recap plant sorting, evaluating and processing (buffing off the remaining tread) on used
tire casings for eventual recap.
Also as you may know, I have too many collector cars; I keep fresh tires on the ones I use
for touring, currently that part of my fleet is down to 12. When I can justify putting on
Michelins, that is what I prefer.
Unfortunately, there are no tires made by Michelin that will really look right on your 60.
I am not sure, as I never had a Chrysler product in that era, but other cars I have had
from the 59-61 period had whitewall widths of around 2 inches, give or take a 1/2 inch or
so, and I don't know of any manufacturer making correct looking tires in a radial. For one
thing, the original bias ply tires have a different shape, with a flat tread, and a fairly
sharp edge defining the sidewall, while radials have pretty close to a round
cross-section. So, your decision really boils down to:
1. are you going to have tires that look right (bias ply in the original size, which was
probably something like 820X15 or even 915X15, check your owner's manual or service manual
for the correct original size) which you can buy from Coker, Lucas, or probably other
vendors (who will know what is correct for your car, including the correct whitewall
width), or
2. If you are going to use the car for touring, and you are not going to insist on
absolutely correct appearance, you can put on radials of the closest available size. Then,
within radials, you have to chose between high quality (which for my money means
Michelin), or wide white radial, which you can buy from Coker also, but do not think of
these as high quality tires. Even if you can buy the correct whitewall width in a radial,
it will still not look exactly right, because of the fundamental shape difference.
On the cars I show, I have a set of correct wide whites (I prefer the Firestone brand, but
there are others, and I buy them from Lucas), and on the cars I use on tours, I have a set
of Michelins. For my mid 50's cars, where the whitewall width is around 3 1/2 inches to 4
inches, I have two sets of wheels, and I mount the wide whites for show, and the Michelins
for long distance touring. Fortunately, all my Packards use the same wheel size, so I only
need one set of really nice show tires unless I am showing more than one car at a time. My
Imperials are 67, 68, 81, and 82, so I can run the Michelins on them all the time, the
whitewall width is correct for the later cars, and a little narrow for the 67-8 cars, but
close enough. But if I had a 60, I guess I would go the two sets of wheels route if I were
going for authenticity but I still wanted to tour with the car. Certainly Radials,
especially good radials, make a world of difference in driving the car.
Size numbering is really easy. The first number "235" is the width of the tire
at the widest point, in millimeters. The second number "75" is the height of the
tire from the rim to the road, expressed as a percentage of the width. The last number
"15" is the rim diameter at the tire bead.
Prior to this system of nomenclature, there was a period where letters were used for the
width measurement, and roughly, for Imperials, "H" corresponds to about
"225" in the newer system, "L" to "235". So an L78-15, which
might be a size on the current crop of bias ply wide whites from Dunlop (also called
Remington, LeMans, Cooper, and others names from specialty stores) would be pretty close
to a 235B75 -15 where the B signifies Bias ply. Of course, it would be a little taller for
the same width (78 instead of 75). The original tire on your 60 (if my assumption is
correct and it is an 820X15) would be 8.2 inches wide (they used to use inches, not
millimeters for the width) and 88% as high as the width (that is what most all tires were
in those days) and of course the same 15 inch rim. So the original tire, if this
assumption is correct would be 8.2 inches wide, 7 1/4 inches from rim to road, on a 15
inch wheel, placing the center point of the wheel at 14 3/4 inches from the road with a
properly inflated tire. There is very little squashing down on a bias ply if it is
correctly inflated, the sidewalls were not designed to belly out like the modern radials
do.
The Letter series wide white from Remington in the same load carrying range would be an
L78 15, and it would be 9.6 inches wide (there are 24.5 millimeters per inch), and roughly
the same height . You can see that this tire will look really wide on your car compared to
the original.
The modern size radial, 235R75 - 15, will be about the same width, but the car will sit
noticeably closer to the road due to the shape of a radial, and this will make it appear
wider still. Some have gone to 70 series tires for instance 235R70 - 15, thinking this
looks more modern, and I suppose they are right if that is what they want, but this tire
is only 6 3/4 from rim to road before it is squashed down by the weight of the car
(another 3/4 inch at least) so you have the center of the wheel only 13 1/2 inches from
the pavement, a full 1 1/4 lower, and a much wider tire. This looks all wrong to my eyes
on a car older than about 1970, but that is just a matter of taste.
I'm going to post this to the whole list, along with part of your question, because there
may be others having the same difficulty getting to that part of the web page. I know
there will be some who disagree with my opinion about what looks right, but I hope the
data about sizes is helpful anyway.

Hi Dick --
Allow me to pick from your mental database for a moment ...
I'm sure that, as the 1960 Imperial that I am buying and taking possession of this week
has not been regularly driven for a couple of years, I will need to replace the tires.
Also, I know that the original bias-ply spare is quietly waiting in the absolutely
IMMACULATE trunk, where do I find more information about the tire size intended for the
wheels? Should I be looking for 235/75 15's?
what exactly do those numbers refer to?

For those of you who think that post-fin cars look best with out WIDE white walls, there
is a picture of a '78 New Yorker Brougham on my website with wide whites.
What Chrysler called "wider whitewalls" were an option on the New Yorker
Brougham from the factory in 1977 and 1978. They were Firestone 500s, I believe, with
1-5/8" whitewall (what is shown on Jon's website) and came only in size JR78-15. They
are perfectly correct (and stunning) on this era car.
This tire was also part of the rare "Salon Package" offered on 1978 NYB 4-door
hardtops, along with aluminum-fascia road wheels, which were a unique wheel treatment to
this package. (These were not the road wheels and they are not the deep-dish all-aluminum
wheel offered on same-year Cordobas and LeBarons. They are a steel wheel with an finned
cast-aluminum insert painted metallic silver-gray and exposed lugs.)
Firestone still (on occasion) manufactures a comparable 235/75 R15 wider-whitewall
"FR721" model of tire, with the same 1-5/8" stripe. I've got them on my '67
and they look great (IMHO) on Imps and big Chryslers from 1962 all the way through the
1970s. It would be a good idea for all of us to write, call or e-mail Firestone to ask
them to keep making this tire, since production seems rather sporadic. And I'm gonna need
another set real soon!

Hi All,
Actually, I'd recommend against a steel wool pad, because little bits of steel will get
imbedded in your whitewall and rust, causing an overall brown tinge.
My husband has always used and swears by SOS (doesn't like Brillo:)). He has used Wesleys
and felt it dried out the sidewalls, so he went back to the SOS.

I keep hearing this from people, and although it sounds true in theory, I've never, ever,
had it happen to me.
In fact, whitewalls are listed as a use for SOS on the box. I also use #0000 steel wool
for chrome, stainless and glass. Never had any ill effects. Obviously, I'm very thorough
about washing off any "particles". SOS is also good for really trashed out
chrome (never on anything in good shape).
By the same token, any type of plastic pad will scratch chrome, glass, stainless. That's
why I don't use them.
But on whitewalls, I suppose it's six of one, half-dozen of another.

If there is, I haven't found it. I like Westley's cause it's cheap, it works, and because
it looks like it's made by a little Mom & Pop petro-chemical company.
I also liked that up until a year or so, it had a very 70s looking car on the label,

Sometimes whitewalls just get old. Try some Comet cleanser on a scrub brush, or maybe an

I do know I have seen raised white letter tires that have been scuffed and the sidewall

If you were to cut a tire in half, you would see in the cross-section that the whitewall
is a laid-in piece of rubber; the reason you see the white showing through on a scuff is
probably because you have gone through the black layer and exposed the white insert...

The best product I have found to clean whitewalls is Easy Off oven cleaner. Spray on your
whitewalls, let stand for 15-20 seconds and wipe off with a rag. I've been using this for
years and may whitewalls are like new. After applying oven cleaner I rinse the tire, dry
and spray with Armour All Extreme Tire Shine. Try it, your tires will look awesome.

>Is there a better product to clean white walls that Wesley Bleche-White?
I just started using Castrol Super Clean on my whitewalls. It was pretty good, maybe not
as powerful as Wesley's, but also not as harsh. One less chemical to buy.
If your whitewalls are slightly off-white, I'd guess the rubber or original white color is
yellowing and maybe cannot be restored. I've read that whitewalls can be re-touched wil
some types of white paints - anyone know?

As I recall, no, they are not the same. The Imperial is the only wheel with the (I
believe) 5" pattern.
I believe that GM uses a 5-on-5 pattern, (at least on trucks) which of course opens up a
world of aftermarket possibilities.
My personal favorite is using some cheapo wagon wheels and stock hubcaps. Get them at
Pep-Boys, Discount Tire, etc. These rims are usually around $25-$30 bucks each w/o centers
(which you won't need). No more junkyard scrounging for rusty rims.
Advantages...
Lighter weight, Improved brake cooling, Wider widths.
I've personally run 8" rims on my '77 NYB. With these I used 235/70R15 tires.
Clearance with the fender skirts was tight, but never a problem. The 8" width was OEM
on GM RWD cop-cars and is the optimum size for these tires. I currently run the same rims
on my '72 Polara.
Trust me purists, these yield a real gain in handling over the stock 5.5"-6.5"
rims. Putting a radial's tread FLAT on the ground is essential. Larger modern tires tend
to become "bowed" on yesterday's rims.
As far as "strength" concerns go, there is a gov't standard for aftermarket
rims. In today's lawyer-happy society, do you really think they'd be selling these rims to
guys with 6,000 lb 4x4 Suburbans if they weren't safe?
>I think we ended up with a f*rd pickup wheel... worked...
I wouldn't recommend this unless it's a real emergency. The Ford rim is slightly smaller
than a Mopar rim at the center. I will "fit" but if you leave it on for any
length of time you may have a hell of a time getting it off. I once had a junker '71
Polara with one Ford rim. I had to beat that baby off with a long pipe.
Right now I'm running 16x7" Ford cop-car rims on my '89 5th Ave, but I used a smaller
carbide bit to enlarge the center hole slightly. (They center themselves with the lugs,
not the center hole).

Hey Jack, was that a '73, or a '72?
When I had my '72 coupe, I needed to get a couple of wheels ('cause mine came with MAGS on
the back!), and the Hollander Interchange book listed '73s and up as different from the
'72s and before (to '67, I think....). Same story with the front brake rotors (if
non-SureBrake). Even though '73 was still a Fuselage-era, it indicated that they'd changed
'em to use the same wheels as MoPar C-bodies (New Yorker, Newport, Polara, Monaco, Fury).
Seems to me that '73 was the year that Chrysler Corp. changed the braking systems on many
of their lines, consolidating and lowering costs. (No more 4-piston calipers for A-bodies,
for instance.) I think this reached all the way up to Imperial, too.
'Course, that old Hollander could've been wrong....

What is the bolt pattern for a 73 Imperial. Will someone measure the center point between
two wheel studs. It will be something around 3 inches. My 57 is 5 1/2 inch bolt pattern
(called 5.5 on 5). 5.5 is the DIAMETER of the bolt pattern. I have a gauge that will tell
me the pattern from the distance between two studs.
Full size GMs are 5x5, Fords and Chebbys are 4.5 or 4.75 on 5. Four bolt wheels are
similar but then, if it only has 4 bolts, it should be considered a spare car, not a real
automobile.
I will be flying to Denver on July 4 to hopefully buy Mark McCue's 73 Imperial and want to
get an extra spare. This is the reason I need to know the answer to this question.

AAHH, well..., SureBrake's a whole 'nother story....
I believe for what turned out to be SureBrake's final year ('73) they used (to use up?)
the same rotors, drums and, therefore, wheels from the previous years. Imperials not so
equipped got the same stuff as the rest o' the C-bodies.
The reason I keep going back to that brake change-over in '73 in this wheel bolt pattern
discussion is because when the rotors were consolidated across the corporation, the '73
Imperial got the smaller bolt pattern. Which means the wheels are not the same as were
used in previous years.
Kerry, if you're coming out here to pick up a '73, and you want to make sure you have an
extra spare, I think you're going to need one on a rim that'll fit a '69-72 NON-Imperial
C-body (New Yorker, Polara, et al), or '73-up C-body/Imperial.
Perhaps Mr. McCue can check on this for you.... 'Cause, I could be wrong (yeah, it
happens....).

Vogue tires were discussed here a few months ago. The messages said these are now made
"off-shore":
"I think Vogue went the way of Firestone and Goodrich and others who shipped their
fabrication over to Asia and ruined their reputations. Boy did they ruin their
reputations. The Vogues I've looked at are obviously inferior products, prone to cup wear
even with front ends properly aligned. The fabricating gauge of the product is obviously
less than the superior Remy line. You don't have to even touch them to observe the
difference.
They look like they have tread from hell, but it's just an illusion since they leave half
of it on the road and is not well-supported underneath. Around here there have been so
many complaints about them and Yokohama, that it prompted a story in the Post's auto
section, a consumer alert on one of the TV stations, and some outlets not carrying them
any longer, Discount being one."
The consensus on the IML has been that Michelin makes a far superior tire. I've got a

"squashed", feel on the road, ride harshness, etc.
But most important, consider safety.
The bottom line for safety is to note the weight of your car, figure that maybe as much as
60% of that could be on the front wheels (yes, I know it's not that bad, but we're being
conservative here), divide that by two and you will get a static load on your front wheels
of perhaps 1500 pounds per wheel. Any tire you buy will have a load rating on the
sidewall: compare that with the weight just calculated and make sure you have a safety
factor, around 25 to 30 % is adequate. This means you need a tire which can carry almost
2000 pounds.

60% of that could be on the front wheels (yes, I know it's not that bad, but we're being
conservative here), divide that by two and you will get a static load on your front wheels
of perhaps 1500 pounds per wheel. Any tire you buy will have a load rating on the
sidewall: compare that with the weight just calculated and make sure you have a safety
factor, around 25 to 30 % is adequate. This means you need a tire which can carry almost
2000 pounds.

>> General makes a 255 70R 15 which looks much better than the 235.
When I bought my '67 in 1989 the original owner had somehow been talked into putting 255s
on the car. They looked like tires from a truck or motor home... simply too large, and
that much tread on a car designed for much narrower 9.15x15 bias-ply tires puts too much
stress on the steering gear and overall suspension geometry.
I switched them to a more compatible 235/75R15 XL (Extra Load) Firestone 721 with an
1-5/8" whitewall soon after and have been happy with the ride, handling and
performance since.

As I am a stickler for perfect performance before perfect appearance, my question is: do
the Firestone 721 tires balance perfectly so as to give a totally (tire) vibration free
ride? I have used Michelins exclusively for this reason only but would like the added
benefit of a wider whitewall provided the tires do not shake-at all and at any speed.
As for 255x70 15's I cannot imagine them being balanceable to zero shake as there is
simply too much mass to compensate for and General has never been noted for its lack of
runout or exceptional quality control. PLEASE correct me if my impressions are incorrect
and they are balanceable and vibration free.

Hello all, I need looking for new tires for my 63 four door. I had Yokohama 235 75R15
radial with a 1 3/8" whitewall for the past three years. An excellent tire, held up
well and looked great, of course Yokohama no longer makes a wide white wall tire. I'm
actually having trouble finding any manufacturer that have a whitewall of 1 3/8". So
what does everyone use on their vehicles. I'd like to avoid going to a standard 1"
whitewall. Please help!

I have recently used a source called Tirenet. I believe it was www.tirenet.com and
purchased Broadway Classic radials in 235/75/15 for my 68 Conv. I believe I paid about
$250 for four. This price included shipping to a local tire store and everything except
$10 each for mount and balance. I am very happy with the appearance and ride. I also
purchased a set of Dunlap 1" whitewalls for my 73 LeBaron and am extremely pleased
with these at around $215 for the set plus mount and balance.

Firestone still periodically manufactures a "721" model of tire in size
235/75R15 that comes exclusively in a 1-5/8" whitewall and is extra-load (XL) rated.
I've recommended it several times before here and have had a set on my '67 Crown for
nearly ten years with good results. I also put a set on my '78 NYB Salon this summer
because they are the exact replacement for the Firestone 721 LR78-15 1-5/8"
"wider whitewall" that came with the Salon Package and were also offered as a
standalone option in 1977 and 1978.
Check your Firestone dealer, and if he says they are not available, make him call the
regional warehouse or find another Firestone dealer.
Because I happened to get mine between production runs, I had to call an old friend at
Bridgestone Firestone corporate HQ and she found me ten tires buried in a warehouse in
Hawaii (the FedEx charges more than made up for the great price, but they should come to
about $75/tire retail). That should not be necessary now as I heard they did this year's
run and they are once again in stock. Be warned, however, that at the time I was
searching, there were 3,300 back orders... hopefully they recognized the popularity of
this tire for collector cars of the 60s and made more than that number.
(By the way, the extra five tires I bought were for a friend and are not available for
sale!)
