You need to do what I think is called the pinch weld mod.mytitan said:i wouldnt go over 285/70/17.
depends on what rims your using.
if u dont want to rub id stay w/ above. i have the prg 4" kit and the above size tires w/ mohave teflons 17x8 and i rub at full turn.
if your using stock wheels, use the above size tire, or even 295/70/17 and u wont lose power and wont rub.
