I just bought new 31x10.5 tires and 15x8.5 rims for my '91 4x4. The backs of the front tires rub a little at full turn, and my explorer looks like it could use a lift. I am wondering what kind of suspension lift to get to stop the rubbing and improve ride quality. Looking to spend under a thousand dollars, and probably get the smallest lift that will work. Any suggestions?
