Hey guys. I bought a truck and it had 31x12.50x20 tires on it. They are hitting my bumper only on the drivers side and hitting the body on both sides. What can I do to be able to run these tires and wheels. I have already installed new torsion keys. It helped quite a bit but not enough. Ruined my ride too. If I dropped down to an 18 inch wheel and put my stock torsion keys back on, what is the biggest tire I can run? Is there any tire size I can run with the 20 inch wheels at stock ride height? I'd really like to take my torsion keys out. Please help guys.
