I just bought torsion keys for my truck and i bought a set of 18 inch Greg Weld Impact wheels with a -12 offset. I was wondering if i got a 285/65/18 (32.5 x 11.5) tire if they would rub on my bumper and inner fender well. Does anyone have or have something similar to this combination on a 2.5" leveled sierra/silverado. PLEASE HELP?
