Installing a 2" RC leveling kit this weekend on my 2016 Silverado 1500. Does anyone know if 285/55R20 BFG KO2 on stock wheels will fit with little to no rub? Or maybe the better question, what is the largest size BFG K02 I could run on stock 20" wheels with a 2" RC leveling kit? I'd prefer to stay away from large wheel spacers if possible.
