A group of four wheel enthusiasts set themselves on fire as they were repairing a tire. While off-roading a tire popped of the rim. It is common for riders to reduce the tire pressure in order to get a larger surface and thus more grip. The problem is it also makes it more likely for the tire to pop off the rim. Normally, an air compressor is used to seal the bead, but this group decided to set the rim on fire, which would expand the gas and cause the tire to seal the bead. But sometimes things don’t go the way you plan.
