Has anyone ever ran a 255/70r15? Just trying to figure out if they would fit or if they would rub.

Trying to get the most width I can, yet still be within the rules of a 70 or 75 series tire on the stock 15" wheel. Only problem I see is the height, 29" tire.

Thanks

PS: Yes I realize this is a truck tire size. This is for a dirt track application. Any other tire size recommendations would be appreciated. Has to be 70 or 75 series 15". "No truck, trick, high performance, or directional tires".

it would work on the back, but not the front

Thats what Im thinking. Might rub on the fronts.

Sounds like I will either have to run a skinny tire or modify the front fenders. Hmmm

I have 275/60r17s on my 88, Id have to go down to a 200/70r15 to get near the same diameter with this rule. Not sure what Im going to have to do.

Anybody good at guessing a tire size by a picture?

For the most part, going taller profile makes the tread width narrower - it is just how tires are made to pass durability tests and real world applications.

29" is a really tall tire and would have a lot of sidewall rollover, plus it would drop the effective gear ratio about 12% vs stock 26" tires.

I have 295/50 15 on the back. Thats pretty wide. I have 265/50 15 on the front any wider and you have serious rubbing issues when you turn. Hope this helps.it will rub just alittle bit when you go all the way. But i have no rubbing issues in the back.
I know your running a stock car and you have rules on tire size. So cutting the wheel wells is not a pro lem,

Right now the car has some old 225/70r15s on the front mounted on some 84 z28 wheels. The rear has some old 215/75b15s mounted on some rallys just to move it around.

Going to try and find a 235/70r15 and see how it looks. Would still like to see how close a 255 or 245 would be.

EDIT: Just wanted to add that a 235/70r15 is almost max you can get on the front. Not much room for anything any taller. Atleast Im not going to push it. Going to run the 235/70
