Wouldn't the answer to this problem be to deflate the tube and remove the valve stem before applying heat?

Nope! I believe the video mentioned a couple of incidents where the valve insert was removed and one where the bead was even broken before starting.
All incidents ended in explosions as the expansion of the air was too fast for the valve to compensate and the expansion even reseated the bead on the tire that had the bead broken down :shock:

Thanks. I hadn't watched it all the way through the first time. He definitely states that that won't keep the tire from blowing.

Do I understand correctly that the whole pyrolisis reaction started from that few seconds of welding, then the tire blew two and a half minutes later? Scary indeed.
That was the way it happened.

very good ! I never realized that could happen, I have never welded or heated up a mounted wheel before, but after seeing this video, I know I will never do such a thing. thanks for sharing this educational video. Jim

This is a real waker upper ain't it?? Never heat the hub on the axle to get off the rusted rim. I always use a 16lb sledge hammer. 8)

There are a lot of welding dangers to look out for;

Look out for the 200lb nitrogen gas filled shocks in car fires and when welding near then. I trust nothing. Murphy's Law. :roll:

Don't put your cutting tanks in the trunk of a car with a electric solenoid opener. Its a great remote control bomb.

Don't run your gas cutting tanks too low. You can actually mix the gasses from one tank into the other tank.

On your gas cutting hoses make sure you have the one way valves on the hoses it prevents the back feeding as well as a flash back going into the welding tank.

Always ask yourself "Is what i'm about to do safe?" (taken from the national timber fallers acc.)
I'm technically misunderstood at times i guess its been this way my whole life so why should it change now.
