I got a flat rear tire. I would like to change it for a tire that holds air. Truck doesn't run ATM. So I can't drive it around the block with lug nuts loosened . Not that I could do that anyway, since the tire is flat. Sprayed it with a load of pb blaster, I pried, pulled and banged it with a BFH now the wheel is bent and still on like it's welded. What's next?
