steel wheels, 2.5" spacers. $5 caps from the swap meet. I staggered the tire sizes, 205/70 front and 225/75 rear.
I have switched to 3" rear and 2" front spacers on the latest truck, all 2.5 made the front wheels to far out and the rear not far enough.
also, if you want to run a trim ring get the ribbed stainless ones from jegs, they are thinner than the huge stock GM type and have a great look.
