'Chemical reaction'?? Nope.
This is purely a physical reaction.
Temp increases on a gas in a confined area is proportionally related. It's called the Gay-Lussic law
Where initial pressure and temp of P1/T1= P2/T2
simply stated: double the temp *kelvin scale* doubles the pressure.
pulling a LONG bead on a rim is going to put a LOT of heat into that confined area.
I break the bead and block the side that's being welded strictly to protect the rubber as most cracks are right on the bead area. Minimally I'll take the core out and let the air out on the rest.

Why is welding on a mounted tire dangerous?
