^^^ this. 33-34x12.5s with 3" lift is ideal. No need to re-gear unless you tow a lot. Even with stock wheels 33s should still clear without rubbing. But if you're lifting and adding bigger shoes, new wheels are a must anyway
33s will fit with no lift, slight rubbing on full turn/stuff.
It depends on wheel specs.
I've got 33s and 1.5" lift in front with slight rubbing, but only at full turn/stuff with unknown spec 16x8 wheels.
I am planning on going up 3/4" to level it when I go to 295/75/16.
I ran a 1.5/2 inch lift and hammered the seams. My 255/85/16s rubbed one side at full lock. There was an alignment issue that never got resolved (something about the cams on the UCAs) before I sold it.
The new owner was going to run spacers (it was aligned, drive straight, etc, just rubbed).
