Right now i have 20 inch rims with 32 inch street tires on my 93 chevy that has a 3 inch body lift. the wheels now are close and i want to buy 33/12.5/15 tires and i have read that they fit on a z71 with a 3 inch body lift but my truck is just 4x4. Will the tires fit on my truck without messing around with the torsion bar?
