Yeah they’re probably not ever going to try that again!
Setting a tire bead the proper way for a tire of this size requires expensive machinery and a safety cage. These guys obviously didn’t have access to such devices so they went for the redneck method of aerosol and a lighter. Things really blew up in their face… quite literally. The explosion in the tire was so large that it actually cracked the rim. These guys are lucky they got out of that situation undamaged.
