just about anything out of an aerosol can that burns quick! My fave is starting fluid. BE CAREFUL USING THIS METHOD!! I've heard a lot of stories about trucks on fire and what not because the people weren't careful. I suggest taking the tire/wheel off the vehicle so it's not close to anything flammable. don't need too much fluid in there, just a few sprays inside the tire and light a match, throw it in, and bam, reseated bead. the heat from reseating the tire will contract after expanding so you usually have to put some more air in the tire after.
