What size are you looking for 17" or 20"? I have the same setup and using the 17" on the ground was no problem, just do not use 4x4 when it is on the ground. I had ours on for about 100 miles when we had a blowout. There are NO plain Jane steel 20" rims for our trucks, so don't keep looking. The cheapest 20" aluminum I could find was through Discount Tire @$128/ea. Several tire stores said they get them in trade once in awhile, when someone wants to upgrade from the factory wheels and I have 2 stores looking for me. Reno has several new Discount tire stores, so that may be your best bet. Also, try any GM dealer for takeoffs, they may have them.
