I took this video during an off-road festival in Calico CA last year. It was my friend Mike's UniMOG which popped a bead, which is like a tractor. The procedure was 2-3 seconds of a combustant (engine starter, hairspray, whatever), wait two seconds and then light it. The expansion will hold the tire to the bead for a bit but gotta start pumping air right away. In the video, we had a compressor attached to the value and running.
For real, it worked well...
