my buddy's truck ahd 315/75/16s on stock rims with a leveling kit and they rubbed then he got some mt classic 2s and they didn't rub anymore.
I've got 315/75/16s on my truck with a leveling kit. Its tight but they fit with just a tiny bit of rubbing.
stock alloy rims with 315's rubbed pretty bad on the control arm with a leveling kit. MT classic 2's in 16"x10" with 4.5" BS and 315's dang near tore the fenders off trying to turn with a leveling kit. 4.5" lift solved that.
