I have a 2006 silverado Vmax. It has a 6 inch suspension lift. i had 33/12.5/17 on it and I just replaced them with 35/12.5/20s. When I turn at all it rubs on the mud flap. I think if I take them off they will rub on the body. What are some opinions on how to fix the problem. 2" body lift? Torsion bar?
