Wheel and Tire Safety Issue

[R_Lefebvre]

Saw this on another forum, and it's worth watching to learn about this issue. There's probably many of us that have or would use heat to loosen lug nuts, weld a wheel for a trail repair, etc. Or even the "explosive" tire bead seating trick could set off this reaction.

I guess the best way to put this in layman's terms, if you apply heat to a wheel, you could set off the tire "smouldering" and it could smoulder for quite some time before exploding. At the end of the video he mentions the "record" for a pyrolisys explosion at 22 hours. And in some cases, the tire exploded even though the valve core was removed.

Wow, this is a really interesting video. Thank you for sharing!

I suppose this is the same process that makes out of control tire fires such a problem to extinguish -- the process is exothermic and doesn't appear to require oxygen.
