No mention in that article of using a flammable liquid or vapor to

split rims from improper technique which have nothing to do with fire.

This is why large truck tires on split rims are inflated in safety
cages.

Thank you for adding value to this discussion, as did Clare, and Amuzi,
where I was unfamiliar with this "split rim" concept until I read the
article you kindly referenced.

Apparently, from the safety alert at the bottom of your reference, these
"split rim" mountings are used mainly for LARGE commercial tires, is that
right?

If so, I wonder what's different about large commercial tires?
o Obviously size is one thing - which could mean more energy
o The pressure per unit area "might" also be different
o Maybe mounting needs determined the reason for the split ring?

Bingo! It would be near impossible to force a big honking truck tire
over the lip of a rim and more so without damaging it.
