Question about stretched tire setups

moore.speed

OP's question still hasn't been answered. I would agree; stretched tires on most (especially a sports car platform) is silly but when talking a very mild amount, it won't be a huge deal.

I had a 255/35 on a 20x10 with a previous car. It was not to the ridiculous and awful looking, tire inside the lip of the wheel because it's so stretched look.. the sidewall of the tire was just simply stretched outwards to fit on the lip of the wheel. 255 was very conservative on the 10" wide wheel in terms of "fitment" or "stretch".

On your 10.5" wheel, you will be fine with a 255/35 but I'd advise taking your front tires and moving them to the rear for the 265 on the 10.5" wheel, if you must go this route. As for the 9.5, I wouldn't want to go any smaller than 235/35 but that is just a mild stretch, as you were looking for.
