    Hi all,

    Quick question. I currently have the optional 5-star wheels on my convertible. Stock tires size is 205-75-15. The car currently has 235-60-15 RWL tires which look a little small (they are actually 1 inch lower than stock) and I'd like to move up to 255-60-15 which is actually the same size. I really need to replace them because they've been on the car for almost 20 years. Wondering if anyone is running that size on the front? If they will clear or rub. I know they will fit on the rear, but ....
    Any help is much appreciated.

    Thanks, john

    255-60-15 clears just fine in the back, but I can't comment on the front. What is the dimensions on the rims? Back spacing and width.

    I'll have to check on the backspacing. They are 7" wide. Anyone out there know? It looks like I can go 215-70-15 on the front which will be almost the same size (26.9 vs 27). Right now my 235-60-15s are only 26.1"

    I run 255-60-15 on the rear and 215-70-15 on the front. Another idea would be to put repro 225-70-15 Goodyear polysteel radials all around for an original look. 20190927_175011.jpg

    255's will rub the torsion bars at full lock. Not hard, but will rub. You will not get as much tread life though as that rim is too narrow at 7"

    Thanks for the advice. I may just run the stock size. I have a 1981 Chrysler data book and it says stock on the wheels was 215 x 70 x 15. I want white letter and that size is available.

    But isn't 235-70-15 an inch too tall?

    According to the tire calculator on "The Tire Rack" web page, the widest tire that will fit safely on a 7" rim is a 235/60.

    I really like the look of the factory original Goodyear polyglass radials. They came in the 215 70 15 size. Reproduction tires are only available in the 225 70 15 size which was used on Corvettes. The tires pictured on my car above are originals. I only put them on for pictures as I don't trust them for regular use at their age.

    I'll stick with the modern BFG size that's around $600 a set!
