bead blaster/ Cheetah / bead seater / bead bazooka?

Get a large ball peen hammer and a 2X4. Stick the 2X4 between the top bead and wheel and pound the bottom bead onto the lower wheel lip going around a little at a time. Seat it GOOD. Then stick the air on the valve and pull up the tire until the top bead seals against the top lip and the tire blows up. Done deal. No ether, no gas, no fire and no injuries.
