s13 with 03' z33 wheels f/17x7.5 r/17x8.
needing new tires and want to know if a 235/40 would be to much for the 7.5 wheel. I know it will fit and that it will bulge slightly, and that bulging can cause less contact patch. researched and cant seem to find anything pertaining to how it performed at an actual autox, just people saying they thats all they run on their daily with 7.5. google found couple bmw threads where e36 came factory with 235 on 7.5, but of coarse 240 and m3 arent the same. Would I be better off just going with a 225/45.

side note: this is local autox and dont care about classing.
