Time for new rear tires and I want to put the largest ones possible without rub. I presently have 235/60R15 on 7" rally two wheels on all four. I'd like to put 275/60R15 on the rear. Does anyone have these on there car with stock springs and shocks without rolling the wheel well lip or any other mods? If so what width wheel and backspacing are you using. Thanks for any help. Al.
