I have a Gen 2 lwb 3.0 V6 with a 2" body lift and 2.5" suspension lift and run 34x11.5x15" Simex Jungle Trekkers these measure out to 34.6x11.9". No rubbing on the rear at all but if I fall into a hole and let the front wheels compress too hard they will rub slightly on the bottom of the guards. I have a 5sp with 4.88 diffs and it is at the limit as far as gearing goes. Never broke a front CV with these tyres even with a front Detroit locker fitted for 12 months. It is having 5.29 diff gears fitted now so that will restore on road driveability and eventually I will upgrade to 35x11.5x15" Simex Centipedes (measure out to 35.5x12.4x15").
