This may be something some of you know about, or not. Either way, I saw a show a couple years back about an 4x4 team crossing of the Artic. They had custom Landcrusiers. Anyway, on that show they showed a quick and easy way to fix a tire that has popped off the bead. They took a can of hairspray and sprayed inside the tire a little, and used a match or something along those lines to ignite the vapors. The mini explosion popped the tire back on the beads. I don't thinks its a method that is great for tires, but its a quick fix in a jam. Anyway, thought someone out there might like to know. I have read some on this site since I found it, think its a great place to gather/share info, and had not run into anyone mentioning that type of bead fix.
