With a 2" hell bent steel leveling kit, I didn't rub with 315/75/16 on stock steel 6.5" wheels. Full lock turns and even driving off road it was fine. If it was really muddy out, the mud would build up in the tires and wheel wells and rub a little mud on mud.
Finally one day I decided to change the trackbar to fix my steering wander. The new track bar, cheap one from Autozone, moved my front axle about 1" towards the passenger side. After that, the driver's side tire would rub on the lower control arm at full lock.
