Those sizes won't fit without a lift. And you will still have slight rubbing until the pinch weld mod is done and the plastic inner fender well liner is heated up and pushed towards the rear.
He was asking what sizes would fit with no lift.
You can run a 245/70R17 or 255/65R17
I ran 247/75 BFG AT with out a lift and NO RUBBING for some time! See my garage thread...
