I know specifically the Indy 500 runs a little thin to begin with. The tread width on my 245/40r17 is a touch over 8" wide. You can see pictures of them mounted in my thread, link is in my sig. they are not pinched on my 17x8 wheels and sit fairly square. Unfortunately I do not believe the Indy 500 comes in 235/40 which I would have recommend, unless they have done size expansions recently. 225/45 my sit slightly stretched, but should keep the sidewalls stiffer and should drive pretty well, as long as the slight stretch doesn't bother you.
