During the operation of a car, it happens that a tubeless tire can no longer be used in normal mode, but in general its condition still allows for further use, but with the use of a pneumatic tube.
There is nothing special about this, just a tube is placed inside the tire, then everything is mounted on the rim and you can continue to use the wheel. But the main advantage of a tubeless tire is that there will be no more air trapped inside after a puncture. Any damage to the tube will cause air to escape from the tube, seep around the rim and exit through the valve hole in the rim, which tube tires is not sealed.
But there is a way to restore the main advantage of a tubeless tire, even if it is already used together with a pneumatic tube. To do this, it is necessary to slightly rework the camera itself.
To do this, cut off the valve from the chamber so that a rubber bead 2-3 mm high remains.
Valve cut diagram: 1 – pneumatic chamber; 2 — cut off part of the valve;Then we carefully clean the resulting cut with a file or sandpaper, so that the flow completely disappears and a flat surface with a hole is formed - a tide.
We stretch the hole a little with our hands and install a valve from a tubeless tire into it, which was previously used on the same wheel. Next, you will need a textolite or fluoroplastic washer, the thickness of which should be 0.8-1.0 mm. It is important that the edges of the washer are rounded.
Then, holding the installed valve from turning, we tighten its head with a nut, the thickness of which should be no more than 3.0 mm. Next, we put a stepped rubber bushing on the valve, after which we insert the valve together with it into the hole in the rim, and tighten everything with a nut, having previously put on the rubber and steel washers.
Before installing the tube, the tire, as well as the rim, must be completely cleaned of dirt and debris, and then evenly applied with talcum powder.

Editor's response
Wheel manufacturers perceive the rubber tube as archaic. But sometimes it becomes indispensable for saving from hernias and cuts.
There are situations when it is not possible to repair a wheel. Let's imagine that at high speed a car crashed into a large hole and damaged two or three wheels. Hernias appeared on them, and one even burst. There is only one spare tire, driving with a hernia is unsafe. What should I do?
Or another situation. The attackers punctured three tires at once with a knife, and the patch (or flagellum) does not maintain air pressure at the cut site. The craftsmen issue a strict verdict: replacement. But where can you get new tires on the road if you have no money? And if there is one, pick it up quickly suitable wheels difficult. It is possible that the inexpensive old wheel models that are on the car have already been discontinued and are no longer sold. Cunning salespeople in stores offer to take new, 2 or 4 wheels at once in a set to ensure the unity of the tread pattern and the same traction properties. But it's hopelessly expensive.
We have to get out and look for temporary solutions to the problem. The most common of them is to install the camera in tubeless tire.
Why is the camera contraindicated?
The fact is that a tubeless tire should structurally work without any layers inside. She has soft sidewalls, which perform their functions only with uniform pressure inside the rubber. The tire then fits tightly to the disk, grips it with its edges and, with the help of a sealant, sticks to it under the influence of friction forces.
But if you put a foreign layer in there, the tire will work differently. Although the rubber tube stretches, in any case it does not fit tightly around the tire from the inside. The pressure on the edges is different. As a result, the rubber becomes deformed and does not compress well from the sides. On high speeds She works out the bumps as necessary. The car receives microplay, noticeable during active taxiing. As a result, due to bending of the rubber, uneven wear tread. But this is not the worst thing.
It’s worse when the tire has a camera inside due to lack of clamping force when hard braking or when maneuvering, it breaks down and is dismantled. And this threatens a sharp loss of controllability. And then - depending on your luck.
In addition, an air gap in the form of a bubble is guaranteed to form between the tire and the tube when inflated by the pump. At speed, such a blister moves inside the wheel and causes imbalance. The wheel beats and gets hot, the steering wheel vibrates. Driving becomes not only dangerous, but also unpleasant.
You can drive, but not for long
However, the camera can be used to get to your home or workshop if the wheel is damaged.
The tire repair technicians will glue in the patch. The tube will hold air pressure, and the tire, as an outer casing, will take the load. This way you can ride even better than on a dock. The main thing is not to forget to put such wheels on rear axle and don't accelerate too quickly. It is best to drive progressively, without acceleration, no higher than 80 km/h. It is strictly forbidden to brake sharply. If you follow these simple rules, a tubeless wheel with a camera will travel several hundred kilometers. And then the damaged tire can be replaced. There is no point in delaying the purchase of new wheels. The camera inside a tubeless camera is a time bomb. Someday it will explode.
Nowadays, in 90% of cases on the roads, cars travel with tubeless tires, this is due to the best performance characteristics unlike their chamber counterparts. But these tires have one indisputable disadvantage - if the rim cord is damaged, sand or other dirt gets into the contact area, the wheel will flatten! And not much, but due to the peculiarities of the structure, a little every day, 0.2 - 0.5 atmospheres. And how to deal with this? Is it possible in tubeless tire put a tire on? Let's find out...
Of course, the tubeless version of the tire now definitely wins in its performance characteristics:
- The wheel is small, but lighter, which has a beneficial effect on handling and fuel consumption
- Fewer elements in the design - there is simply no camera, it does not need to be straightened before installation
- The inner area of the tire is made of special material, even if you puncture the tire (a nail or other “object” gets in), the tire will not go flat right away. Rubber compound envelops the puncture site and the air comes out very slowly, you can ride for several days until you find a surprise in the tire.
Here are just some of the advantages of tubeless tires, of course there are also disadvantages, at least such that they are 20% more expensive than their tube counterparts, but process can't stop.
It goes down, nothing can be done
However, there are times when a tubeless tire goes flat, and no matter what you do, it won’t stop!
This mainly occurs due to damage to the wheel rim. Let’s say you flew into a hole and dented a (stamped) disc, they straightened it out for you, but some unevenness may remain, the tire will not fit tightly and will leak air, albeit not quickly, but the next day minus 0.3 atmospheres, possibly more.
It could also be a problem with the paint on the disc. The thing is that the varnish and paint can come off over time, swell, and again the tire does not fit tightly to the wheel. The tire goes flat, it seems trivial, but it frequent malfunction on used alloy wheels! They need to be cleaned and...
Of course, the damage to the tire itself should not be written off; with strong impacts it can break (the cord itself breaks), there is no use installing any tubes here, the tire needs to be completely replaced.
There are also trivial reasons, for example, dirt (or sand) at the tire fitting where the tire is attached to the rim. Here you just need to clean the contact area.
Tube for tubeless tires
In general, to be honest, a tube is not installed in a tubeless tire. After all, think logically:
If the tire or wheel has been damaged so badly that even after repair (straightening, sealing) it still goes flat, then something is wrong. Rather, the geometry is broken, and riding on such a wheel is VERY DANGEROUS! Especially if it is installed at the front. Personally, I would replace it.
But there are times when even a normal one, which has never fallen into a hole, descends. There are two solutions - either sand and dirt got into the joint (try cleaning it), or you need to sand and paint the disc (maybe it will help).
BUT a Russian person has one beast inside known as a “toad”, which does not give money for a new wheel (tire + disk), especially if the size is large! Imagine an R18 - R20 with a low-profile tire, the amount is not small, that’s what car enthusiasts are trying to get by with “ little blood", namely, installed in a tubeless tire, regular tire, and it seems like the problem is solved!
Is it worth doing this? And is it even possible to do this? There are a lot of opinions, at professional tire shops and manufacturers of the rubber themselves, they will definitely assure you - WHAT IS NOT IMPOSSIBLE! And here are the reasons:
- The rim for a tubeless wheel, like the tire itself, are not designed for mounting a tire! There is some truth in this, if only because the “nipple” of the camera will dangle in the place where the tubeless disc is mounted, since the dimension is larger. He could easily come off.
- The internal space of a tubeless camera is smaller, and if you put the camera inside, it will not straighten out completely and wrinkles will appear.
- When you install a tube, particles of air space, some “bubbles,” may form between it and the tire itself, because the tire will also try to seal interior space. This has a bad effect on both balance and handling. The bubble can move around inside, causing the tire to wear unevenly and cause bald spots to appear.
All this can lead to dire consequences; the tire may simply burst! It happened in my practice that the nipple was torn off, so the rubber came off very quickly.
My experience
Guys, I also dealt with such tuning of a tubeless wheel, I also installed a camera in a tubeless wheel, it was because I was young, I didn’t have enough money, and the disc was not fresh. In general, the camera was installed at rear wheel, originally it was in the front, but I decided to rearrange it so that if it bursts the car wouldn’t skid. I had a rear wheel drive for about two seasons, but I used the car 95% of the time only in the city, and did not develop high speeds on the highway. Indeed, the wheel was poorly balanced, for some reason the balance was off, but still it achieved intelligible indicators for movement with no high speeds.
After two seasons, it really seemed to me that the tire was not worn evenly, so I bought new wheels, regular stamping, and new tubeless tires.
Actually, my statement of facts is that you can drive, BUT BE VERY CAREFUL! If you often travel at high speeds (highway), then personally I would replace the wheel completely. Ideally, you can throw it on the spare tire, that’s where the wheel belongs. It is generally prohibited to place it on the front axle, because you don’t know what to expect from this wheel. And yes, after a couple of seasons, and maybe even after one (if the mileage is high), the tire will wear out, and not evenly, you won’t be able to get away from it.
Hernia on the wheel, will a camera help?
What I definitely wouldn’t do is repair a hernia, or what’s also called a “bump,” with a camera!
We talked about why it comes out, in short, the lower metal and fabric cord of the wheel, which holds the rubber, breaks and the pressure simply bursts the tire in this situation. THIS MEANS SHE CAN BREAK OUT AT ANY MOMENT! And believe me, you can’t do anything with a camera - 100%! If the lump bursts, the chamber will burst immediately, it will not be able to withstand the pressure inside, because it does not have reinforcing elements - IT WILL BURST LIKE A BALL.
Now in 90% of cases on the roads, cars travel with tubeless tires, this is due to better performance characteristics in contrast to their tube counterparts. But these tires have one indisputable disadvantage - if the rim cord is damaged, sand or other dirt gets into the contact area, the wheel will flatten!

WITH cast and forged wheels It’s even more difficult if you fly into a hole, they can simply burst, or microcracks will appear through which the tire will go flat. Of course, it is possible to straighten and solder them, but it is difficult and not always worth doing, because the structure of the disk is damaged (if the damage is serious).
It could also be a problem with the paint on the disc. The thing is that the varnish and paint can come off over time, swell, and again the tire does not fit tightly to the wheel. A flat tire seems trivial, but this is a common problem on used alloy wheels! They need to be cleaned and paint correctly.
Of course, the damage to the tire itself should not be written off; with strong impacts it can break (the cord itself breaks), there is no use installing any tubes here, the tire needs to be completely replaced.

Restore your rims, maybe you just need to paint them or just clean the mounting area. If it doesn’t help and there was a blow, BETTER THINK ABOUT REPLACEMENT, WHEELS ARE NOT THE SAVINGS!
