00:00When an unseated heavy equipment tire has a gap too wide for compressed air,
00:04mechanics use a dangerous shortcut called explosive bead seeding.
00:09In the freezing dark of an industrial quarry,
00:11this worker ignites aerosol fluid inside the rim with a long torch.
00:16Watch the rapid combustion.
00:17The flash fireball vaporizes the air inside,
00:20creating a massive thermal pressure spike.
00:23In a fraction of a second, the pressure slams the multi-ton rubber bead
00:27onto the steel rim with an explosive mechanical pop.
00:30Extreme garage physics on a 50-ton mining truck.
