Top Gear had this in the Polar Challenge special. Given it’s one of those same Toyota HiLux utes that appears to have been modified by Arctic Trucks (they’re in Iceland), you gotta wonder if the tyres were designed this way!
The tires are designed to have very low pressure to provide the widest footprint possible so they don’t sink into snow or slip too much on ice. The tire slipping off is a side effect of that.
This method was used on specially modified Toyota trucks that were crossing the arctic.
“kurisu7885″ is correct. The intentionally low pressure was an advantage – and a drawback.
If they don’t add any air then when the air inside the tire cools it will break the seal again, you always add air, they just don’t fully inflate the tires
Actually, the rapid expansion of gasses could be persistent. Most of the inflation would be due to the breakdown of hydrocarbons in the hairspray propellent, not just the air getting hot.
Well, having a 20 year old diesel pickup, and needing ‘starting fluid’ to help it now and again, this was a new technique to me, and I’m glad to have seen it.
Now I know a quick fix to the issue of a tire being so flat as not to be on the rim anymore (such as most of the vehicles and trailers that my dad owns), so you can start pumping it. The big concern I have with the technique on ‘normal’ cars, and especially trucks with high pressure tires is leftover unburnt fuel, sealed in a big tire, and adding 20% oxygen to it under pressure. So definitely use as little as possible when replicating this trick, and drive as directly as is convenient to a service station to swap for ‘fresh’ air. Because you could be making a bomb that blows up rather powerfully right in your face as you inflate it.
Most tires, you WOULD have to pump it up afterwards, but I can’t tell whether they deliberately deflated this tire afterwards, or it had a big leak, because it’s flat again shortly after that guy reaches into the rim. Possibly they’re demonstrating the ‘trick’ over and over again.
I’ve done this before fo tires that have come off the bead as well. It’s best to remove the valve in the valve stem to allow overpressure to escape. Once that tire seats on the bead, if the starter fluid’s still burning, it’s building pressure with nowhere to go. Removing the valve allows that pressure to bleed off.
@evildave – It deflated again because the gasses in the tire got cold again after the fire went out. You have tho be ready to quickly inflate the tire after using this trick. All it does is set the bead on the rim, which can be a pain even with the right equipment.
I think you’ll find the reason its so low at the end is the guy who walks up to let the air out so the next person can have a go (looks like a training class to me)
Although you are right that this only seats the tire and you do still need to put air into it after
not a fail.. this is one of the most common offroad fixes goin… its just to seat the bead.. you still to to inflate a little bit… that said, when offroad we run a seriously LOW tire pressure.. it helps with grip and lower the chance of a puncture or slice… we all have onboard air compressors for airing up before driving home.. but there is not enough pressure in a cheap onboard compressor to seat the bead… hence, a littler explosive action to the rescue..
also note, the truck needs to be jacked up before you do this… and its not advised to be so close to it.. we usually throw a match at it.. if by chance the tire were to blow-out, there is enough pressure to stop your heart.
This technique actually came up during a discussion at the truck stop where I work. It is a fairly well known quick fix as long as, as already noted, you have a compressor handy to reinflate the tire before the air in it cools and it slips back off. It can also be, as also noted, extremely dangerous and potentially lethal if you use too much accellerant. Because of the potential for deadly mishap, at least I was informed, doing this is officially illegal in most places within the US.
Then again, law enforcement officers are unlikely to be hanging around if you’re in a situation where this actually becomes an option, so I guess the illegality is more of one of those unofficial “at your own risk” warnings.
Saw this trick done on Ice Road Truckers too, with diesel fuel, no less! It really came in handy there- they used it on the inner wheel of a duallie, out on the road.
This is not a Kludge at all! This method of using either gas and a match or lighter has been used for years as a way of seating the bead on a tire. That’s right kids I just told you what to use and how to do it. Blow off your arm at your own risk.
Fix it with fire!
yes, fix it just like these guys also did: http://senorgif.memebase.com/2010/10/01/funny-gifs-quick-fix/
urrr…its the same guys

Not an uncommon way to seat a tire if you don’t have the machines at hand. You still have to pump it up afterwards.
No they don’t. They keep the tire at low pressure on purpose to give it a wider footprint.
If they don’t add any air then when the air inside the tire cools it will break the seal again, you always add air, they just don’t fully inflate the tires

not hairspray, starting fluid. the binders in hairspray attack the rubber of the tires.
Been there .. done that. Been using this method since i was about 8 years old to change semi tires with my dad
Didn’t fix so much : look at the tire on the very last sec.
Retard.
Yeah, but that’s what the guy with the compressor is for. The flame just set the tire in the bead so he could inflate it.
Funny, we were just talking about this trick at work the other day.
This one is as old as the hills and twice as dusty.

Like this!

There is a convenient little reply button that allows you to reply without putting @ at the beginning…
I think they do that to fix tires that come off the wheels inside bothe artic circles.

just take a gallon of gas and it works.

Us rednecks have been doing this for years. You should see how we balance ‘em.
it’s “WE rednecks”
don’t make it seem like all rednecks have bad grammar.
its ether and a lighter and hes setting the bead on the tire… once again not a kludge happens all the time
As several others have said, this is not a kludge.
This video is from a gathering of offroad enthusiasts in Norway.
And the propellant he’s using is a can of “CRC 5-56″
This is not a Kludge at all! This method of using either gas and a match or lighter has been used for years as a way of seating the bead on a tire. That’s right kids I just told you what to use and how to do it. Blow off your arm at your own risk.

Has surprised. Everyone so can. With a cylinder that. Here let with gasoline so will make!
Tire and fire rhyme for a reason.
