i have a gen 2 rx7 and i was wondering what is the biggest tire i can use.

 

245/275 have been fit with just a little rolling upward of the fender inner-lip

with 20mmF and 30mmR afterkarket wide fenders you can fit a 265 up front a 295 out back, maybe even a 315 but I have yet to see it or try it.

a lot of corner carvers like a 255 all around setup with 9's up front and 10's out back but some street driving people like a 275 out back for good grip.

a +35 or +30 offset out back will let you run a 275 on anything from a 9 to a 10 inch wheel.

 

thanks
