Yours are 18” but mine were 20’s and ANY truck with stamped steel upper control arms with 20” wheels WILL rub with just 275/60/20’s. Reason being, leveling changes your UCA’s and brings your wheel and tires closer to the UCA’s causing rubbing. Lots of people saying not true and later posting elsewhere “yeah, slight rubbing” but to each their own. Btw, Michelin Defenders are stronger than most AT tires on the market, designed to handle the extra torque from trucks, AT tires are much more versatile but even a C rated tires will have softer sidewalls than an E. Just about every quality tire manufacturer makes C rated AT tires, just depends on the size and whether someone is willing to compromise for a smoother ride. I’ve always had E rated tires but that was my first and last time I’ll ever level a truck. Ok, good luck to everyone and do lots of research before messing with your suspension angles, sometimes better to save a bit more and lift it the right way. [emoji6] Sent from Above
