Start with stock OD of tire and work backwards. U have 5x5 rims so u need to work with that. Proper offset, rim width, backspacing is critical. Than work from stock tire OD backwards. U probably have 225/70/15 tires? Or approx? Go with 60/16 or 55/17 and so on. Too bad there are tons of cheap GM suv wheels but they are all 6 bolt.
