As in the past life of working and the chuckles are at the expense of a friend. We both laugh hard about this. My regret is that the conservative side of me said for the longest time said no to this technique and what a huge mistake that was - huge! It's like many things - use it in moderation and it's fine. We worked so much harder than we had to. This is for problem tires only.
And a sacrifice was made.
So just how hot was it? I don't think the small explosion made the valve stem that hot but the air in the tire was and it happened when the air was escaping that it got real hot quickly. You need to stop the air or else the tire will come back off the rim which was the problem in the first place. I do not miss this at all!
