I am getting new rims and I was wondering what size tire I need to go with for a 17x9 wheel. Im not exactly sure but i think the stock gt wheels ar 17x8. I am clueless on this subject.
you can fit up to 275/40/17, same size wheel and tire on 03-04 cobras. 255/40 17 will also fit fine. I would go with either of those sizes. Other sizes will fit also but would not look as good imho.
