the gaz burn in the tire.

when it's burning the air becomes hot in the tire.

the air when hot ,takes more volume that cold so it expands and push the tire to the interior sides of the rim.

@michaelovitch

About what you said : during combustion of the spray you have a great volume of gas because of the sudden rise of temperature but when it cool down the gaz loose volume and yes the tire can retract and pop out.

In fact you have only expansion of the gaz not of the mass of it: that mean you need to inflate it like you said.

i agree with you, you need to inflate after the trick

the title of the vid is inappropriate.

@WishGuu

that's right : this trick is just used to seat the bead.

it's often used in 4x4 enthusiasts, their tires often pop out because of low pressure they use.

you have to inflate that after.

or you use this trick without the valve core : it's allow you to reseat the bead without the risk of seeing the tire pop out and to move your car even with the atmospheric pressure in the tire.

@michaelovitch

If like you say, the elevation of volume during the combustion is only due to the elevation of heat, this trick is just usefull to seat the bead. Then, you'll need to inflate de tire.

What I said is : if this trick inflates the tire for a long time, then that means that the combustion released more gaz than the initial gaz, which can be !

@WishGuu

not flat : the bead is seated and that's the point of this trick.

of course pressure drop when the gaz is burned because the temp drop.

the heat is the cause of gaz expansion in this case not the contrary .

those tires needs very low pressure to be efficient.

if you don't want the bead pop off just remove the valve core.

look at my vids i did few tires.

@michaelovitch

Then the air becomes colder and the tire becomes flat again.

You don't have the right answer : the gases from the combustion of the initial gaz take more volume. The heat is only a secondary effect.

super dangereux complètement fou de montrer ça sur internet

comment il fait ca !!!

[Maisonfeuspectateur]

not only it extends due to heat, but burning also provides much gas.

LOL tre marrant mais cet interdit ça mon gars!
