Have used the flame method plenty of times over the years. I always pull the valve, spray deodorant usually, and light her up. Have never had an issue and has gotten me out of the poo on more than one occasion.

I agree @Throbbinhood. Too many people making assumptions without ever doing it I assume. I can reseat a bead in minutes vs using any other method
Would imagine that our Northern Hemisphere 'Arctic' members probably have no other option with those massive tyres, have seen many a documentary of them all doing it in below freezing temps! I am just about to install a quick release dump valve on my 20L/150psi chassis mounted tank powered up by the ARB twin which should do the trick also on the 35x12.5R15 KM2s hopefully:-)

It's worth having a look at this video from Bridgestone which shows what happens when Pyrolysis occurs. https://www.youtube.com/watch?v=jBUVzgCHHuA
This was the result of a short weld being done on a rim, but the principal is the same. If you apply heat and the tyre goes into a Pyrolysis situation, it can turn deadly in a very short space of time. This is an extreme case but there is substantial heat generated using lighter fluid etc and basically causing an explosion inside the tyre. Is it enough to cause pyrolysis? I don't know and really don't want to find out. Maybe as a last resort in an emergency if all other methods have failed, but I wouldnt be using it as my goto method of seating beads.
Years ago i was fleet manager for a large trucking company, we had one of the semi tippers hit some power lines when he forgot to lower the hoist. The driver leapt free of the cab and was walking near the rear of the truck a few minutes later, one of the rear tyres actually snapped all of the lugs holding the spider rim on as it hyper inflated from pyrolysis and shot the wheel about 50 metres through a fence. The wheel missed him and a bystander by about a metre, I have no doubt they would have died had it hit them. We had to put a 300 metre exclusion zone around the truck for 24 hours due to the risk of further pyrolysis, we couldn't tow it away and just had to wait for the 24hr period. We actually hired a security company to make sure no one came within coo-ee of the truck overnight. 22 tyres, all trashed as a precautionary measure at a cost of around $8,000.
Wow, great video thanks Steve, never knew about Pyrolysis reaction mate, scary as hell :-( Noticed in the last few minutes he said the record reaction time was 22hrs later, holy crap!
Sort of puts it into perspective doesn't it , if I had no option and was miles from anywhere it would be in the back of my mind I suppose but do the risks out weigh the benefit .
I've done it a hundred times mate never had a problem , yeah well maybe 101 times might be your number .
Thanks Steve. That does it for me. Using flame to seat a tyre will be a very, very last resort for me. I had the pyrolysis in mind when I started the thread, but had no idea it could be that potent from such a small ignition source.
If you've ever had a wet or muddy 35" or 37" tyre off a rim, then it's a quick and easy solution, but be careful. Enough is enough, too much can be dangerous. Don't use those portable stove gas cans as the accelerant, use a quicker flash point like an aluminum based deodorant. Same result, but you can use less. I saw a guy use a gas can once, nearly took his head off.
I believe what's shocked me personally from Steve's video is the possibility of even simply heating up some of my rusty property 'say' trailer/sled wheelnuts or tacking up a rim I guess. There must definitely be something to it if Bridgestone feels the need to kindly educate us folks. Evil Twin some years back was subliminally in fact the guiding light for me to use my onboard air tank to its full potential :-)
