I have a 1997 z28 convertible and will be needing new tires soon. I would like to have 275s up front and 315s on the rear but I don’t want any rubbing issues and don’t want to have to do anything to the bump stops or fenders. What are the biggest tires I could get without any rubbing issues? Also I will be needing new rims so what size should I go with the same all around? Any feedback helps thank you.
