... in that photo with the tire looking like its on fire, where you guys just resetting the bead on the rim?
Just for the record - The broken-down vehicle was
not part of our group. He was blocking one of the trails so, we stopped to offer a "not-so-quick" hand. This guy had a 14" wide wheel an the tire was obviously narrower than safely optimal and to add to the challenge... it was an E rated tire. He had the wrong bolt pattern wheel for a spare :exclaim: and didn't have a jack

or an emergency brake :yikes

as he informed us as we were setting up one of our Hi-Lift jacks) oh, and he was on an incline. Tyson wisely rolled the largest boulder possible in front of the rear tire to mitigate the danger (How's your back today?).
After the compressed CO2 couldn't even bead the tire we tried to widen it with ratcheting tie downs but it was one stout E rated tire with zero sidewall flex. About a 1/2 hour or more later we resorted to the combustion method (only as a last resort). We of course had a fire extinguisher in hand. I was holding it in my right hand, and yes that is me in the photo with the 'Ewwwwwwwwe' look on my face. But what you can't tell by that photo was that reaction was a cat-like reflex because the flame was about 2 times higher a millisecond or so later - which resulted in one of our comrades getting his eyebrows and front hair singed, the other lost all his arm hair up to his shirt. It was quite humorous.
We got the tire beaded, remounted and he was on his way. The guy was extremely grateful and I hope he learned a valuable lesson - be prepared on the trail. (and fire is a great hair remover)
