I insalled a 2" AutoSpring leveling kit and 305/55R20 Nitto Terra Grapplers. I am happy I did this and love the results. My only concern is that when I am at a full left turn my tires rub big time. I have the stock 20" King Ranch wheels what can I do to fix this problem? Am I causing any major damage?

 

It is probably just rubbing on the sway bar but you might want to look under and make sure it is not rubbing the UCA. If it is only doing this in tight places at slow speed like parking lots then you probably have nothing to worry about. Mine rub both the left and right sway bar at full lock. Your only options with keeping those tires are new wheels with different offset or spacers if you feel like you cant live with the rubbing.
