Check out the Whitewall thread. There's a few good options still out there. Though they are few and far between. :(

Wrong sizes though. I mean he could go 235/75 because that's what hearses and limousines use, but the OE tire size for the sedans is 235/70.

Sigma Shadows, from onlinetiredealer.com. You can get the biggies 235/75 in a nice white wall.

Check with your local Kelly-Springfield dealer. The Navigator Golds are quality WWs, available in 235/75 and made in the USA.

I looked at tires for my '96 on TireRack site too . I remember seeing different brands including Michelin,Avon, Goodyear . I would like to buy a V Speed Code and 4 season and Avon seems to fit the bill . However I have no experice with that brand at all

I installed Avon Turbosteel 70 Whitewall 235/70-15 tyres (that's the way the Brits spell tires :) ) on my former pride and joy 1984 Rolls-Royce Silver Spirit back in 2004. They are high performance tires with a "V" speed rating.

All non-turbocharged RR's and Bentleys from the 1970's through 1995 used the 235/70-15 tire size and factory specs were at least an "H" speed rating and the Avons were one step higher with the "V" rating. By 1995, the last year RR used the 235/70-15 tire size, the suppliers for RR were Avon and Goodyear, the Goodyears for the RR's were made in Luxembourg - I had 2 sets of the Goodyear "V" rated Euro tires on two different RR's and both sets cupped quickly like domestic Goodyears: junk.

I bought 3 of my 235/70-15 Avon Turbosteel 70 tires through www.tirerack.com although I don't believe they carry the Avon brand currently, and if they do, the 235/70-15 tire size hasn't been available from them for quite some time. The reason I purchased only three tires from tirerack was because of availability, the fourth tire came from the RR dealer at twice the price, and they weren't that cheap from tirerack to begin with, I believe I paid over $200 per tire.

The Avons seem to hold up well, my friend who bought the RR from me back in 2006 still has them on the car and they are not giving him any complaints. The Avon tires seem to be a replica of the original equipment Michelin tires from the 1970's and early 1980's (replicas of the original Michelin available through Coker for $477 each http://store.cokertire.com/235-70hr15-michelin-xvs.html ) and I'd say the tread design of the Avon and vintage Michelin doesn't appear to be all that contemporary but they work.

The turbo Bentley models, and 1995 turbo RR Flying Spur, used the Avon Turbospeed CR27, I had them on my 1989 Turbo R, the CR27 is available only in 255/65-15 for 15" sizes, and I believe they went on a wider wheel on that car.

Here is a link to the Avon website showing the Turbosteel 70:

Good luck! :)

Why do you want a V-rated tire on your FWB? That's 149mph. They're limited from the factory at (I believe) 108.

The table in the link above shows the equivalent tire for a 235/70-15 could be a 225/75-15 if you want to go with a 75 series tire. The 225/75-15 was the premium tire size used in the 1977-1979 Fleetwood Brougham models and factory made Cadillac Limousines from 1977-1984, plus 1990-92 Brougham. Although the 225/75-15 size is not correct for the 93-96 Fleetwoods it may, nevertheless, give you more options for the increasingly scarce WW's in the 235/70-15 size. :)

Sting, The V-rated tire has extra sidewall bracing which helps reduce side to side swaying, especially nice on a heavy car if you're inclined to take corners faster.

As noted above, the RR and Bentley cars used the higher speed rating tires not only because those cars are capable of high speeds in the European driving environment but also the RR's weigh over 5000#'s, so handling the weight can only be done safely with the stronger speed rated tires.

A 93-96 Cadillac Fleetwood weighs, if I remember right, less than 4500#'s, and, Sting, if you're right about a speed governor, the need for a speed rated tire on the Cadillac is not essential for safety but should increase handling for the spirited driver who likes to speed through corners. :)

A related story, on the 1990 Brougham d'Elegance I owned about 7 or 8 years ago, it had the 350 V8 with the towing package - rode like an ox cart - I decided to put new tires on it and went with a 235/70-15 Goodyear Eagle RS-A WW, V-rated, not the Euro made Goodyear referred to above. Lots of RR drivers used this tire when it came in whitewall still.

Anyway, the 350/factory tow package equipped Brougham I had rode rough to begin with and with the V-rated tires it handled very, very well, but the ride was even more stiff - I couldn't believe that was possible! I took those tires off and and put on some, if I remember right, Firestone FR380's and they were better, but I still unloaded that car because of the horrible ride. They guy who bought it already had a 90 Brougham with the same package and he thought the car was great.

Live and learn... :)

Ah, I never thought about the sidewall stiffening in higher speed rated tires.

Intriguing... :)

Go and jiggle your Caprice from side to side and notice how it wobbles. A V-rated tire, or even an XL tire, on the same car will be hard to move like that. The difference is in the handling but most Cadillac drivers want the luxury cushy ride so that's why the Cads use "S" rated tires because the sidewalls have more compliance. :)

Don't worry, Dave. Soon it'll be on 17 or 18 inch wheels, so I won't have movement like that either. :thumbsup:

Also, it is very easy to reprogram the PCM to allow a higher (or unlimited) top speed. A stock 94-96 FWB will easily hit 140 with no limiter.
