Alright i've got some Pro Comp 17x9 wheels with 4.75 backspacing and -6mm offset. I run a 33 12.50 17 right now on the with no rubbing issues with no lift. I have an opportunity to pick up some 315 70 17 BFG A/T's really cheap. Will my wheels have enough backpace to run these tires along with the OME HD lift without rubbing?

 

Yea that's the same size wheel I run. You'll be fine the only rubbing I intially had was on the plastic air damn.

 

If it can help, I run 315/70R17 Duratrac with 17x9 5.5" Backspacing (+12mm offset). No rubbing at all even at full flex. My lift is 2.5" Teraflex BB.

I think 5" backspacing would have been the limit, otherwise the tire would hit the fenders at full flex. With more lift it would be fine.

 

I run 4.75" with 37"s and no rubbing. My wheels are 17x9 Pro Comp 8179s.
