Don't try this at home, just for off-road experts

When you are out in the middle of nowhere 4-wheeling through the back country, it is no time for a flat. Here is a trick only the truly daring should try.

Take a small bottle of propane with you, those tiny green or blue ones. When the tires bead slips and you get a flat you press the propane tank against the valve stem filling the tire up slightly with propane. Add fire around the bead and the resulting explosion acts as a vacuum sucking in air while pushing the tire back on to the rim.
