my fix for this, take a big hammer, remove the tire and in the back beat the pinch weld so it is flat and the tire rubs a flat surface thus not tearing it up. in the front cut the outer fender so it doesn't rub and beat all the ruff surfaces in the fender flat so it doesn't tear the tire up. thats what i did and i also did 2" bumpstops in the front and no bumpstops in the rear. it works good enough for me with 33's and 3" lift!
