That looks like a neat piece of kit! Simple and safe too.

Even with the strap, and the bazooka in the background,
these guys opted for the flames!

With the flame you have little if any control.



What ever could go wrong?

No mention in that article of using a flammable liquid or vapor to
seat the bead explosively.

Tyres have the potential to *create their own* flammable gas inside the
tyre. It is why those truck tyres explode and why an inert gas
(nitrogen) is used to fill them.

No - neither statement is true. Tire "explosions" on the road do NOT
include deflagration - any fire is due to overheated rubber bursting
into flame long after it has lost inflation.

They do on haul trucks. That's why the large mining companies here have
a tyre company under contract to do all tyre maintenance work.

OK - you are talking Pyrolysis - the same process used to form "wood
gas" - which again ONLY happens on an OVERHEATED tire - due to either
extreme overlood or low tire pressure (same thing, actually- as a
tire's load rating decreases with lower pressure) The tire must reach
about 200C - or roughly 400F for pyrolysis to occur. And nitrogen
fill will not prevent a pyrolysis explosion because you can never
keep ALL oxygen out of the tire. It may reduce the risk, but the
PRIMARY reason for nitrogen fill is pressure regulation - Nitrogen
molecules are larger and less likely to migrate out of the tire - thus
holding pressure better - and since loss of pressure is a MAIN cause
of pyrolysis, it WILL reduce pyrolysis problems.A properly inflated
and loaded tire will NEVER reach pyrolysis temperatures and one of
Otraco's main jobs is monitoring tire inflation and temperature.

Their presence made life a lot easier for the haultruck fitters.

This company has a large presence in this country

Yea, what a "downer"!!!

Indeed! LOL




Plenty of stories about exploding tires on
split rims from improper technique which have nothing to do with fire.

Changed plenty of them over the years - it's more about incompetent
operators than it is about the split rims.

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