Very much a "get you home" fix, but it DOES work. You just need to be able to put more air in that tire right away, before the gas cools and the tire deflates again.
'tis kinda how they mount tractor tires on those big steel rims, too. Seen that done. Or some guys will have a special air tank that blasts air out so fast the tire has no option but to expand and lock onto the beads. Fun stuff either way.
I've seen this a few times and always wondered, if it's the hot air expanding that makes it work, when the air cools.... Won't the tyre just fall off again?
tire went flat and came off the rim, tires need to be set to the bead (thick part near the edge of the inner part of the tire) to hold onto the rim. With out a proper tire machine - this is usually very difficult in the outdoors. The spray can has something flammable (ether, starting fluid, even some hair sprays), when sprayed in and ignited - the air basically explodes and expands rapidly in all directions, re-seating the tire
I dunno how fine the margin is, but I've seen someone cross it. It was pretty evident from the get go they had no clue what they were doing, like pouring lighter fluid all over the outside of the tire.
Worked in a tire shop for 5 years and you'd be surprised how strong/robust tires are in some ways, and how absolutely insanely weak they are in others. Tires are designed to both get hot (not this hot, but still pretty hot) and holy lots of pressure.
You tend to go less in more til its enough. I've had to to do the quite a few times. Not recommended to do but you can also use a quick shot of mapp gas or propane if you have one of those hand held torches.
That's definitely not true. I dunno just how much of a dumbass you guys be to screw this up, but if you're a significant enough dumbass, you can still screw it up pretty badly.
As soon as the bead is set the flames have no more o2 so it goes out. This guy used more than I would. But I never tried this while it was on a car. We did this on the tire machine.
I did this twice to inflate a small tractor tire. My butthole was clenched the entire time. Also, you need to immediately hit it with air to inflate the tire.
Rubber against the road has to face a lot more kinetic and potential energy than a few spritz' of butane burning. It won't catch the rubber on fire from just that little flame. To do that, you would have to burn an entire jerry can worth of petrol in one spot continuously
We are not talking about the same "problem". What you say is completely valid, but so is my answer to the question I thought you were posing. 'Ave a cheery day, mate. God shave the queen and all that jazz
this is an old school trick that's used because it works. If the bead is too dirty, or you don't have something to air it up with immediately, it wont work.

as a certified city boy I had about a five year obsession with offroading, saw this done IRL several times. Still have no idea how this works.

Exactly what are they spraying? I've tried this with various cans of stuff I had to inflate a motorcycle tire, and they wouldn't ignite.

nameisunavailable
Yeah it will pop back off again, this is just to set the bead so when you connect the compressor it will actually keep the air in the tire.
hellothisispeggy
Yeah you have to have an air tank and start adding air immediately as as soon as it cools it'll pop back off again.

Saw this for the first time in a documentary of scientists crossing Antarctica in jacked up badass Landcruisers.

Scientists? They were the three British nutters from Top Gear....
igglebotato
That was the north pole, and I don't recall them doing this (though it's been a while since I saw that episode)
Trunkmonkay
They did. Which is why the other guy mentioned it.
SpiderTrike2000
But it has a puncture? No ?
Grey406
When offroading, you lower the pressure to 6-12 PSI in the tires to massively increase the contact patch and float over the ground 1/2 -->
Grey406
2/2 to reduce rolling resistance against obstacles, but sometimes too much force on the sidewall can make the bead pop loose from the wheel
Acc87
Probably just slipped of the rim due to low tire pressure. In bog like that you run very low pressure for maximum surface area

I will never not find this impressive, but also wonder how fine the margin is between success and catastrophe.
lolactiq
we did it a lot in the Army. Usually we'd put the tire in a cage first. It works really well until it doesn't
DorkJedi
pretty wide on the big offroad wheels. You CAN blow it and yourself to smithereens, but the most common result is failure to lock bead.
aguacatedeldiablo

There is no catastrophic failure mode to this technique.

TeamRobot
I have literally seen multiple examples on this very platform of people getting it very wrong. Not sure they still had eyebrows afterwards
sabrinadiesatdawn
I don't count that as catastrophic. Catastrophic is "someone is permanently disabled" or "vehicle is destroyed"
TeamRobot
Ok, fair point.

You do have to inflate the tire quick afterward, or the vacuum as the hot gas shrinks can de-seat it again
OldnSpicey
I did this twice to inflate a small tractor tire. My butthole was clenched the entire time. Also, you need to immediately hit it with air to inflate the tire.
LauchMan
Do I have to use premium air or is normal air sufficient?
DaveLeche24
Another “fine margin” is your choice of words… “my butthole was clenched, hit it”🤣😂
MeatPopsicleMultiPass
That's why I usually have air already hooked to the plug that's pumping air.

If you put too much, it can explode

Im not talking about burning the rubber, im talking about eyebrows and skin. Have you not seen the many ka-booms on this here very site?

OldnSpicey
YES! This just seats the bead, you still need to have some air to inflate the tire.
seehemewe
Didn’t know what a bead was in this context, googled it and TIL it is the term for the lip of the rubber tire that “hooks” into the metal wheel
In a case like this, seems like lots of mud so it could easily be dirty, could you even clean it unless you lifted up the truck?
FlyByGRider
Just a rag and some water around the inside of the rim and the part of the tire that's going to meet it.
gatormarc
Looks like they washed the bead out with a couple of bottles of water -- one still on the ground next to the tire.
gatormarc
It's a temp fix.
seehemewe
A temp fix where you can drive to the tire place / gas station, probably saves a LOT of time waiting for and paying for a tow truck
