If youâre a regular driver, you may have had the bad luck of experiencing a broken tire bead.
Hitting the curb or pothole, or even a quick sharp turn can result in an unseated tire bead, making the tire impossible to re-inflate.
Reseating the bead by taking it to a workshop might not be the most viable option when youâre left stranded in the middle of a road.
But do not worry because there is a rather quick (albeit dangerous) fix to pop a tire back on the rim.
All you need is some combustible fluid, a source of ignition, and a little faith in science. Just spray a little starter fluid outside the rim, and light it on fire. The expanding gas will push the sidewalls of the tire up and out, causing the tire bead to snap back into place.
You would require the following items to perform this task:
Follow the steps outlined below to properly seat a tire back on the bead:
Step 1: Lift the tire up from the groundElevate the wheel off the ground with the help of a jack. If youâve already disassembled the wheel, place the rim inside the tire and lay it flat on the ground.
Donât have a jack?
Well, donât worry you can check out our guide to jacking up a car without a jack!
Carefully spray some starter fluid in the cavity created by the rim and the sidewall of the tire.
Make sure you donât spray too much of the liquid as that might damage the sidewall of the tire.
Once youâve sprayed it around the entire bead, spray a little off the edge of the tire and onto the floor in a straight line.
Be extremely cautious with the amount of fluid that you spray onto the wheel.
Starter fluid is highly flammable. Using exorbitant amounts of such combustible liquid can cause a fire that might be difficult to contain.
Due to this reason, always keep a fire extinguisher nearby.
Using a lighter, matchstick, or whatever source of ignition you have, light up the starter fluid starting from the link you previously made on the ground.
This step must be carried out immediately after spraying the tire bead so that the fluid does not evaporate away.
You might want to step back and distance yourself a bit after this step as it will cause an explosion.
The fire will cause the gases in the wheel to ignite and expand rapidly.
This sudden expansion of gases (an explosion) will cause the tire beads to move along the wheel and catch the grooves, seating them back in place.
As soon as you hear a popping sound, put out the fire as soon as possible.
This indicates that your tire is seated back onto the rim.
Finally, pump air into the tire using an air pump and youâre all set to hit the road again!
There are some disadvantages that come along with this method of popping tires back onto the rim. If not done properly, this can result in Pyrolysis, which is basically the thermal decomposition of the tire.
Pyrolysis can not only cause chemical deterioration of the tire over time but can also lead to a full-blown-out explosion.
The pressure inside may rise up to 7000 kPa and seriously injure anyone in close proximity to the tire.
Watch this video to learn the science behind using fire:
This is why you must always put off the fire as soon as you hear the âpopâ sound â usually a couple of seconds after you light up the fire.
Any kind of clicking or popping sound from your carâs tires is a cause for alarm, and something not to be taken lightly.
Sounds coming from a vehicleâs wheels might be due to an underlying problem in one (or more) of the following parts:
In order to find out the exact cause of trouble, you would need to take the car for a road test.
However, before you do that, make sure that there isnât something dangling off your vehicle or a broken car part causing the noise.
Using fire might be a convenient way to pop your tire back onto the rim, but it surely isnât the safest. Playing with combustible fluids and fires can be very risky and dangerous if you donât know what youâre doing exactly.
Always try to seek help from a professional first, and if that isnât possible, only then should you try pulling off such a feat. Just make sure that you abide by all the necessary safety protocols, and you should probably be fine.

Was 2021 a great year? Not exactly! But we did have some posts that did good traffic.
Take a walk down memory lane with us, as we think back on 2021, a year that will seem much better by this time in 2022.
The internet is awash with people using a spritz or two of brake cleaner or starter fluid to bang set a bead on a tire. As you can see above, thereâs a right way and a wrong way.
Getting a tire to mount right on a rim can be a challenge. Hell, I spent a week trying to mount my first tubeless mountain bike tires a few months back and found a lot of the same tips and tricks being used there as you find in the four-wheeled off road and stance car scenes.
The central problem is you want a tire to press right on up to the inside lip of the rim and kind of lock in place. Tires have a kind of raised edge right at the inside lip, and rims have a raised edge, too, on the inside of their outer edge. As you inflate the tire, its bead pushes out to the edge of the rim and forms its airtight seal. This is called âsetting the bead,â and usually itâs a pretty easy job both on a bike or a car tire.
Pumping up the tire with air is usually enough to set the bead on anything ordinary, and if itâs tough, slightly overfilling the tire with air will get you the pop ... pop ... ping! of the bead seating. Amazingly, I dug up some fantastically low-res images on government websites that I am free to use to illustrate my point.
Here you can see a fueleconomy.gov diagram of a car tire, with its lipped bead:
Illustration: FuelEconomy.gov
And here is how that bead seats into a rim, as seen in a NHTSA cutaway:

Sometimes, though, a tough tire on a wide rim will not quite want to work its way to the bead. This is why you see people lubricating the bead with soapy water when mounting a tire.
Itâs also why you see some people (particularly those in the off-roading world) use a ratchet strap to help set a bead. The idea in this case is to press the tire down and out towards the lip of the rim, doing some of the work for you before you start trying to blast air into the tire.
Hereâs an example:
And hereâs a more low-tech example on a small tractor tire using a rope:
Both of these methods help you out if you donât have a giant air compressor to get a huge blast of air in to really pop in a tricky bead. But what else gives you a big blast of air pressure? An explosion! This is the fundamental theory of using fire to set a bead. There really isnât that much fuel needed to get even a pretty big tire to set its bead, as seen here on a Jeep:
You see the same technique in the world of stance cars fairly often, as people try and mount tires on wider and wider wheels. Even a pretty normal tire will need some help to stretch out and meet the lip of the rim. Hereâs Hoonigan doing it with a strong âdonât try this at homeâ warning a few years back:
Car And Driver also has its own step-by-step guide to using fire to set a bead while out in the field, with similar intonations not to do this. As someone who grew up in California and had to live through many a smoke-filled summer from wildfires, I, too, would not encourage anyone to do this while in a dry field or pine forest they happen to be Jeepâing through.
As you can see in the videos, not a ton of combustable fluid is at hand. Too much of an explosion and you risk not just inflating the tire enough to set the bead, but enough to blow out the tire altogether.
Thatâs exactly what happens in this video uploaded to Redditâs terrifying What Could Go Wrong subreddit. The video itself is overflowing with wonderful Brazilian energy, and every word in Portuguese uttered is dripping with confidence, even as the guy dumps basically a full Mountain Dewâs worth of gas into this tractor tire:

The best I can do otherwise is give you a frame-by-frame.

Let us first enjoy the optimism presented here.
What could go wrong, indeed!

A key element of this process is to slap the tire first, patting it as you would a horse.

Here we can see a truly large volume of combustable liquid going into the tire. How much liquid? Too much.

The guys hook up air to the tire â fire might set the bead, but this air is meant to keep it set and filled with air. Our hero in the blue jeans is making a safety trail of fluid that could have been longer, honestly. A few hundred feet would have been comfortable for me.

Our second and only other safety measure is to use a lit rag on a stick to set things off. Ear protection? Nah. Eye protection? Nah. Rag on a stick! Youâre good, bud.

Here, for just a moment, we see that this actually worked! The bead, as you can see in this frame, is set. Look at how snug that giant tire is to the bead.
Perfection.

And just one frame later, our failure is more than present. The explosion of the tire blowing out is enough to distort reality. Our protagonist has turned wiggly. I would not want to be an ear drum anywhere near this.
Screenshot: Redditâs r/WCGW
Here, also, is a good view of the tire itself blowing out. You can have too much of a good thing.
Screenshot: Redditâs r/WCGW
And here is our aftermath. The bead is not set, the tire is on fire, and the windows on the tractor are trash. We have now entered into a new calculus of wondering â would it have taken less time to set this bead using a non-explosive method than it will take now to fix the broken glass on this John Deere? We may never know.

Not all motorists keep foot pumps in their trunks. Many are limited to conventional electric compressors, which do not take up much space in the trunk and pump the wheels perfectly. However, they have an annoying feature. Compressors burn fuses in the car when connected to the cigarette lighter. Therefore, at the right time, this electrical device can simply stand in the middle of the tire inflation process. The wheel remains inoperable. How to bring the pressure to the values ââââprescribed by the manufacturer?
The best solution is to find an assistant. Usually, motorists are responsive on the track and help drivers in trouble. Asking for a pump or compressor is easy. Often truck drivers come to the rescue. Any truck with air brakes can supply dry air at high pressure through a hose with a nipple nozzle. Therefore, the wheels will be inflated quickly.
If there are no trucks nearby, and up to 0.
5 atm is left in the tires, then you can drive to the nearest gas station and find the necessary equipment in the store, including a tire repair kit. The main thing - when driving, do not exceed 60 km / h, turn on the alarm and avoid sudden braking. Otherwise, a sagging and limp tire can be torn off the rim.
In addition to a shop with the necessary accessories, many gas stations have a free tire inflation point. It is very easy to use it. It is enough to fix the nozzle on the nipple, set the required pressure on the shield and press the green button. The pump will inflate the tire and then turn off.
When the tire is completely flat, you can put on the spare tire and continue on your way. However, in the absence of it, or if two wheels are punctured in an area where there are no assistants and trucks never pass, you will have to resort to completely radical ways to save the car from trouble. The most memorable way is to inflate tires with a fuel explosion.
It is necessary to remove the wheel from the car, find a puncture, remove a nail or other object sticking out of the rubber, and then screw a thick self-tapping screw into the hole, which will temporarily serve as a plug if there is no repair kit and flagella at hand.
Next, completely deflate the tire and disassemble it.
Then we pour about 50 grams of gasoline inside the tire, spin the wheel so that the fuel spreads over it, and wait for it to evaporate. Next, we make a small torch at the end of a long - about a meter - branch and bring an open fire to the wheel. Gasoline vapors explode and the wheel instantly inflates. The more gasoline vapors exploded, the tighter the wheel will inflate. However, the nominal pressure of the gases is not reached. Perhaps there will be 0.5 atm., But this is enough to continue the journey to the gas station or to the tire fitting.
During this experiment, be careful not to spill gasoline on your hands or on the wheel. When a torch is brought up, the fuel may ignite and burn the tire.
Therefore, it is better to keep a fire extinguisher ready.
Another piece of advice from the experts behind the wheel. They were experimenting with alternative ways to inflate tires. If you hammer a wooden plug into the exhaust pipe, drill a hole in the center of which and pass the hose through, you can inflate the tires up to 1-1.5 atm. The pressure in the exhaust system reaches 2 atm. True, on the side of the road it is difficult to quickly make an adapter from the exhaust pipe to the hose. It must be done in advance and carried with you.
Another way is more plausible. If you find a long hose and fasten the tips on both ends with clamps, then with it you can transfer pressure from other wheels. If you release about a quarter of the pressure from each of the three wheels, then enough air will be collected in the deflated and repaired to continue moving. True, not every driver carries a spare pump tip with him.
In general, in order to avoid such painful problems with the wheels, it is better to throw a foot pump in the trunk that will not burn out and burn the cigarette lighter, and stock up a spare repair kit with a set of flagella and self-tapping screws.
Then the problems with the wheels will recede by themselves.

Surprising gadgets were found in the trunks of Soviet drivers! Give some of them to a modern car owner, and not everyone will even understand what it is and how to use it. "Wheels" try to regularly dig up unusual artifacts in order to preserve the memory of our automotive history. Today we are testing a rare device for repairing wheels on the road - a vulcanizing briquette.
In general, fire as a tire fitter's assistant is known to many today.
With its help, it is possible in the field (and not only in the field) to pull a large-diameter tubeless tire onto the rim. To do this, it is enough to splash a bit of gasoline under the tire half-mounted on the disk, and after it turns into a state of flammable vapors in a few minutes, bring a stick burning at the end. Flash, pop and the accompanying release of a large amount of gases instantly put the tire on the disk humps.
This "magic" was unfamiliar to our grandfathers due to the lack of tubeless tires in everyday life. However, they also often used burning gasoline to repair the wheel, but in a slightly different way.
A classic of the genre â a chauffeur's trick from the time of the Great Patriotic War, with the help of which the chambers of the wheels of cargo "one and a half" were glued in the field. A patch of so-called âraw rubberâ (unvulcanized rubber) was applied to the hole, and on top of it, through several layers of newspaper, an old piston from the engine was placed like a glass.
Gasoline was poured into the piston and set on fire. Such a simple device warmed up the place of gluing to 140-150 degrees, due to which the rubber vulcanized, turning into a state of durable and elastic rubber.
In the post-war years, a curious car accessory appeared, designed to replace sealing with a piston on the road. It was called "vulcanization briquette". Actually, in almost any book on the operation of the "victory", "Muscovite", "Zhiguli" or truck in the 50-70s of the twentieth century, one could find a mention of a vulcanization briquette. It was, in fact, a pyro-heater, but it did not require gasoline for operation, and therefore it was much safer to use and more convenient.
From the book "Automotive Tires", Military Publishing House of the Ministry of the Armed Forces of the USSR, 1946:
To ignite the combustible composition in the briquette, it was necessary to slightly loosen it with something sharp (with a knife or nail), and then set it on fire with a match.
If the combustible mass did not ignite well, it was proposed to inflate it slightly. Actually, the hygroscopicity of the composition was the reason for the unpopularity of vulcanization briquettes in the driver's community ... A puncture of a wheel is not such a frequent misfortune, and the briquettes lay for a long time in tool boxes and trunks, where they inevitably dampened, despite the rather dense packaging. And at the right moment, they often turned out to be useless.
From Motorcycle Maintenance and Repair, 1956:
There were several slightly different subspecies of vulcanization briquettes, but in fact they were all a metal "tray" with low sides filled with a combustible composition - usually something like cellulose-wood chips impregnated with saltpeter. On the bottom of the tray (from the outside, of course, side) was stuck a patch of raw rubber. From the rubber, it was necessary to tear off the layer of cellophane film protecting it from drying out, apply a briquette to the previously cleaned and degreased puncture site on the chamber, press it with a clamp and set it on fire.
When the burned-out briquette cooled down, the patch was guaranteed to be glued with high quality due to the calculated combustion temperature, the amount of fuel in the briquette and its cooling time of about ten minutes.
Despite the fact that vulcanization briquettes were primarily aimed at motorists (although I even met their mention in the book âField Repair of Aircraftâ, Voenizdat publishing house, 1943), they made the most sense for owners of light motorcycles and mopeds without a generator (with only a magneto), as well as for cyclists who have neither a source of electricity nor a supply of gasoline.
Surprisingly, but not something rare and scarce in the past, today it is almost impossible to find a vulcanization briquette live. For some unknown reason, it has become an incredible rarity - there are practically no live photos of this accessory either in Google or Yandex. There are only numerous references in the old automotive literature.
However, nothing is impossible for "Koles" - we, although with great difficulty, got a couple of copies of this really rare driver's device, and conducted an exclusive retro test.
The vulcanization briquettes that fell into our hands were produced by the Barnaul Chemical Plant. It is even strange that this enterprise still exists and is still engaged in the production of materials for repairing tubes and tires.
Our briquettes were made in 1964. Since then, they have been waiting in the wings for 54 years untouched ... And despite the obvious rudiments of the historical and cultural value of these retro accessories, we could not resist trying the aliens from the ancient auto era.
After thorough drying and replacement of a patch of raw rubber that had hardened for half a century with a fresh one, we tried to seal a car chamber with them.
You can see the result in the photo: the old car "artifact" did not fail, worked exactly according to the instructions and vulcanized the patch on the chamber.
Well, "made in the USSR" sounds proud even half a century later.
