It’s pretty rare to get a flat tire when you have a tubeless setup. The sealant inside your tires will quickly seal small holes and cuts to keep you rolling on the road or trail. However, flats are always possible – even with tubeless. Whether you’ve discovered your tire is flat after storing it in the garage, or you lose pressure after a sudden impact with a rock, we have you covered with the tips you need. Check out our guide to fixing your tubeless flat and getting back out on your ride.

PRO TIP: Opt for plastic tire levers over metal ones. They won’t scratch the surface of your rim and they are lighter and easier to carry!
If you find a large hole or gash in the tire that cannot be fixed with sealant alone, you’ll need to patch the tire and you might even need to install a tube until you arrive home.PRO TIP: If the last bit is super tight, start back at the top and use your hands to wiggle the tire into the center of the rim. Just like you did at the beginning to loosen the bead from the rim, this creates extra slack in the tire and will make it easier to get onto the rim. While you wiggle the tire push down. When you get to the bottom, you might be able to pop that tire on with your bare hands!
Then, just give it a spin and squeeze your brake to make sure everything works like it should. Nice job!How to Choose the Right Saddle

While a tubeless setup is certainly less likely to puncture than a tubed tire, there is still a possibility for air loss.
Therefore, you should be prepared with the correct knowledge and tools to fix a tubeless puncture on the trail and at home. Here are the most common tubeless issues you might encounter and how to fix them!
Never heard of tubeless? In our ultimate guide to MTB tubeless, we explain everything you need to know about tubeless setup, tires and much more!
There are a host of different scenarios that lead to a puncture or air loss on the trail but in the end, you always have one goal: seal the system so it can hold air again. With a tubeless setup, this job is often quickly taken care of by the sealant, meaning small thorns etc aren’t that problem. IMPORTANT: renew your sealant every 6 months (or every time you change a tire) to make sure it is able to work as effectively as possible.
Luckily, tubeless punctures are relatively rare. However, if you do find yourself with a deflated tire this guide will help you get back on the trail ASAP!
We also recommend carrying a spare tube, just in case!Depending on the severity of the problem, fixing a tubeless puncture can take less than a minute with the right tools. You will need a mini-pump (or Co2 cartridge and inflator), a tubeless tire plug set (click here to read our tire plug group test), a tire patch and a tube for the worst case. Luckily, it is possible to store all of these tools without needing to wear a backpack. They will easily fit into a hip pack (we tested 24 in a big hip pack group test), or even on your bike.
Fixable on the trail? Yes
Time needed for repair: 1-5 minutes
This kind of puncture is caused by small thorns, sharp rocks or nails etc on the trail. It is probably the most common tubeless puncture, and luckily also one of the easiest to fix. In fact, you might have already punctured on the trail without realising, as the tubeless sealant in your tires often seals these small punctures immediately.
If, however, the hole is too big for the sealant to fix on its own – often caused by a pinch flat – you will need a tubeless plug kit. The first step is to find the hole (or holes) and wipe away any surrounding dirt. If you are riding in a group, ask a buddy to keep their finger over it to minimise air-loss. Then, quickly thread the tire plug through the plug installer.
Depending on the size of the hole and the plugs, there are two techniques to plug the tire. For smaller punctures, push the plug into the hole until it fully disappears inside the tire. Then carefully pull the installer out, until 5-10 mm of the plug is visible. Use your fingers to hold the plug in place and remove the installer. If you are sealing bigger punctures with larger plugs, push the plug into the tire just over halfway, so that a “V” shape is left, and remove the installer.
Once the plug is installed, spin the wheel to let the sealant coat the tire and re-inflate if needed. In our experience, if installed correctly, tubeless plugs can last the lifetime of the tire and do not need to be removed. However, it is worth trimming the exposed plug to prevent it from ripping out under heavy braking.
Fixable on the trail? Yes
Time needed for repair: 1-5 mins
You’re flying down the trail, pushing around a tight berm and suddenly hear a loud “braaaap”! Your rear tire is not leaking, but it has definitely lost air… What happened?! You have rolled the tire so hard across the rim that the tire bead has pulled away from the rim, briefly letting a lot of air escape, before popping back in place and closing the gap between the rim and tire.
In short, you have burped a tire. There are two possible causes: either you were running very low tire pressure, compromising your tire’s stability or you just hit the turn really really hard. Either way, the fix is simple. All you have to do is re-inflate the tire and keep riding. We recommend checking out our Tire Pressure Guide to find your perfect pressure and prevent burping in the future. You should also top up your sealant before your next ride, as you most likely lost some during the burp. If you burp on a regular basis, even with high tire pressures, you are very likely running a tire that is too wide for your rim width.
Fixable on the trail? No, install a tube and fix at home
A cut sidewall is usually caused by long, sharp rocks which cut a long slit into the tire. These punctures are too big for tire plugs and sealant to seal. Your only option is to install a tube and ride home. If the cut is really big, try protecting the tube by sticking some tape or plastic etc in between the tire and the tube.
Depending on the severity of the damage, you can try fixing the tire at home by thoroughly cleaning the tire inside and out, roughening up the inside of the tire with sandpaper and applying a tire patch with vulcanising glue. Otherwise, the tire is a write-off.
Fixable on the trail? No, install a tube and fix at home
Time needed for repair: 20+ mins
If a spoke punctures through the tubeless rim tape, you will quickly start losing air through the spoke holes. Unfortunately, there is no easy fix and you will have to install a tube to get you home (make sure the spoke is not protruding into the rim bed!). In order to fix the issue at home, remove the tire and the rim tape and clean the rim thoroughly. If spoked snapped, replace it… Make sure you know why the spoke punched through the tape: check for even spoke tension and make sure your rim is an intact running true.
Re-tape the rim (with new tape) and set up tubeless. Check out our Ultimate Guide to Tubeless for everything you need to know!
Fixable on the trail? No
If your rim is damaged and leaking air, it’s time to (carefully) head home.If you have dented your rim and it is losing air, the only option is to install a tube and carefully ride home. Make sure to thoroughly inspect the rim first – if the damage is too bad you will have to walk back.
Fixable on the trail? Likely
Time needed for repair: 5-10 mins
If your valve is leaking, try tightening the lock-nut that holds it in place. Sometimes they rattle loose, causing the leak. Admittedly, we all have bent or somehow messed with our valve core trailside. When releasing air for example… If your valve core is broken, no need to panic.
You often carry one around inside your spare tube without even knowing! Remove the core from the spare tube, carefully remove the one from the tubeless valve (this will let all the air out of the tire) and install the spare valve core. Pump the tire back up and ride on.
Are you doing everything right, yet still ending most rides in deflated disappointment? You are probably running the wrong tires! Luckily, we have put together a massive tubeless MTB tire group test, so you can find the perfect tire for your bike!
With the correct setup and tire choice, tubeless punctures are very rare. However, if you are caught off-guard and puncture, we hope the tips above will get you back onto the trail ASAP. Tubeless punctures are not scary, and definitely not a reason to stick with a tubed setup. Remember, you can always install a tube and ride home!

Car repair,
Each of the drivers may have such a situation when a tubeless tire deflated on the way, but the spare tire was not in the car, or for a long road this is already the second wheel. In this case, there are only two ways out - one way or another, wait for help from others (take the wheel to a tire fitting, call to bring a spare tire, call a tow truck, etc.), or you can repair a punctured tire yourself. nine0003
Before moving on to the topic itself, it is worthwhile to carefully study all aspects of the operation of tubeless tires, but their widespread use has clearly proved that they have a clear advantage over tube wheels.
The main advantage for the driver is the ease of repair, because if a wheel with a chamber is punctured, it will have to be removed and disassembled in order to remove the chamber, and only then carry out the repair itself, and then you will have to do laborious work (if it is done without special equipment) in reverse order. Tubeless tires, in most cases, can be repaired without dismantling the wheel, and without even removing it from the car. nine0003
In addition, when punctured, a tubeless tire deflates for a long time, and sometimes drivers ride with several nails or self-tapping screws in the wheel without noticing the problem for up to several months. Therefore, if necessary, you can pump up a wheel with a puncture and have time to get to the nearest tire service.
However, there are several nuances that complicate operation. For example, with a strong impact on the edge of a pit or a curb, the tire can depressurize and instantly deflate, or if the wheel is not completely deflated, it can disassemble during a turn, which will lead to an instant descent.
nine0003
Also, such a wheel is very difficult to inflate with a conventional pump or a mobile compressor, if it is disassembled (flew off the disk), in this case a professional compressor with high pressure is needed.
Usually, this procedure is not too difficult, and the puncture site is easily detected by visual inspection due to the culprit of the damage, which remains in the tread.
Alternatively, a soapy solution of any soapy liquid or plain water may help. By pouring on the tire with our “puncture indicator”, you can quickly find the required place by the emerging air bubbles. nine0003
But in the case when there is no soap or water, you have to carefully inspect the tire, while listening to hissing and trying to find the puncture site with your hand. This method helped me repeatedly in deaf and deserted places.
Using a tubeless sealant is the easiest and fastest way to repair a wheel and get to a professional tire shop.
If you do not have such a can, then we advise you to buy it, sooner or later - it will save your nerves, time and mood. nine0003
And so, if there is a nail or screw left in the tire, then it should not be removed immediately, first we connect the bottle with sealant to the nipple and if the bottle is new, then we completely inflate the wheel, if there is already insufficient pressure left in it, then before repair will need to pump up the wheel to at least 1 atmosphere.
After the sealant is pumped into the wheel, it is necessary to remove the foreign object, and the sealant under air pressure will seal the puncture site from the inside, but remember that this method of repair is temporary, and it will last for about 100 km, which is enough for a visit tire fitting. nine0003
It should also be remembered that the use of sealant disturbs the balance, and you cannot drive fast on such a wheel, the safest speed will be about 60 km / h.
This method is the most correct for emergency road repairs.
Similar kits are sold in any automotive store, and even in any large supermarket. The kit usually includes a special awl to expand the puncture, a hook for the lace, the laces themselves with bituminous impregnation and, in some cases, glue. nine0003
Before carrying out repairs, in order not to spoil the integrity of the cord (the inner hard part of the wheel made of steel wire and nylon thread), it is worth reducing the pressure to 1 atmosphere. Then you should use an awl to clean and widen the hole, without which you will not be able to insert the lace. But you should not immediately remove the awl from the hole, otherwise the tire will release all the pressure and insert the lace will not work.
Then you should put the cord into the eye of the hook, distributing it equally on each side, after which the awl is taken out and the hook with the cord is put into the hole formed, here you should treat the action carefully and not overdo it. The lace should go into the tire about half or a little more (the sealing harness should be folded in half).
nine0003
After that, it is necessary to pull out the hook with one sharp movement, while the tourniquet will remain in the tire. Repair can be considered completed after cutting off excess pieces of lace and pumping the wheel to the required pressure.
It is worth noting that when using high-quality sets, this repair is considered to be complete and the puncture will be securely closed until the end of the wheel's service life. The only thing that may be required is balancing.
However, if the damage to the wheel is serious, then you will have to take care of buying a new tire. Recall that it is forbidden to repair cuts on the wheel, such a wheel is no longer allowed for operation even as a spare. Therefore, it is better to choose a cheaper tire than to pay for the repair of a cut, especially since today you can choose a new wheel even through your phone or from your home computer by visiting a specialized website.
For example, one of these sites is the online store of tires and disks Internet-shina.ru at http://www.internet-shina.ru. nine

Modern passenger cars are equipped with tubeless tires. Tires with rubber chambers inside are extremely rare today, only on super-budget vehicle options. Car owners have long appreciated all the convenience and benefits that tubeless tires have. Unlike chambered rubber, they keep air in the wheels by being sealed to the rim.
The tightness of tubeless tires is ensured by a two-millimeter layer of rubber applied to the tire from the inside. It is he who prevents the passage of air. The coating of soft rubber layer provides tightness at the junction of the tire with the rim of the rim. The tire bead sits on the so-called rim shelf, which is equipped with a special rounded ledge. Thanks to him, the tire is securely connected to the wheel rim, and complete tightness of the joint is achieved. A tubeless tire is filled with air through a valve installed on the rim, on its rim. nine0003
Why did tubeless tires become so popular that they gradually replaced tubed tires? First, tubeless tires are much lighter. This is a very important and great advantage, because heavy weight enhances the inertial movement of the wheel when driving on, to put it mildly, imperfect road surfaces, which we still have much more than smooth autobahns. As a result, this affects the condition of the chassis, accelerates its wear.
In addition, tubeless tires do not heat up during driving in the same way that chamber rubber heated up, in which the inner cylinder rubbed against the tire while driving. Such friction led to its rapid wear, and also increased the likelihood of tire rupture during movement. When a tube is punctured, the tube tire loses air very quickly, since it escapes not only from the puncture site, but also through leaky tire beads that do not fit snugly against the rim shelf. In addition, if such a tire is punctured, you will not be able to stop the car immediately, it will travel more than a dozen meters by inertia until it comes to a complete stop. During this time, the tube and the tire can be damaged more thoroughly, the rubber of the inner cylinder will “chew”. With tubeless tires, this option is excluded. Even if a puncture occurs, thanks to the tightness of the chamber and its periodic pumping, you can get to the tire service. nine0003
Tubeless and tube tires also differ in how they are mounted / dismantled.
If chambered rubber can be freely disassembled or, conversely, installed at home, then such a number will not work with a tubeless one - the risk of damaging the side flanges is too high, damage to which will lead to depressurization of the tire. Due to the peculiarities of installation and dismantling, many motorists find it impossible to repair a tubeless tire with their own hands, especially on the road, not in a comfortable garage, but on the side of the road. And in vain. Of course, it will not be possible to completely eliminate the problem at a professional level without special equipment. But to make sure that the damaged tire still travels, and sometimes not only reaches the tire fitting center, but goes more than one hundred kilometers after an impromptu repair, is quite realistic. nine0003
To do this, use special tire repair kits, which can be purchased everywhere today by going to any car shop. Better yet, buy everything you need to repair a tubeless wheel yourself separately and always have it ready.
By doing this, you will save some money, which is always nice. The fact is that manufacturers of ready-made repair kits, in an effort to make their kits more expensive and solid in appearance, include in them both really useful tools and materials, as well as those that you can easily do without. Using repair kits or separately purchased harnesses and tools, you can repair tubeless tires not only for cars, but also for trucks. This can also be regarded as one of the advantages of tubeless tires over tube tires. It is much more difficult to repair it with a puncture. It is necessary to disassemble the wheel, remove the chamber, find the puncture site, and then degrease the working area, cut out the patch, and seal the rubber balloon. After drying, the camera is installed in place, and the wheel is beaded. With a tubeless tire, everything is much easier. nine0003
RUNWAY Tubeless Tire Repair Kit, 7-Piece
If you find that your car's tubeless tire wheel is damaged, first assess the severity of the situation.
If, in your opinion, you can do without repair, having reached a reliable tire service on periodic pumping of the wheel, then it’s better to do so. Tubeless tires were designed to hold air even with foreign objects sticking out of the cord. But do not forget that riding with a nail or other object in the tire causes the puncture to gradually expand and the tire around the damaged area begins to gradually collapse. nine0003
But, if it so happens that the damage to the wheel received on the road is too extensive, the chamber does not hold air and it will not be possible to complete the journey while inflating the tire, you need to choose the best method of temporary repair and start it immediately. A tubeless tire is repaired in the following ways:
When choosing a repair using a tourniquet, you need to decide what type of material will be used. The harness can be cord or rubber. Let's consider both of these options. nine0003
Wheel repair kit, 6 pieces
Cord harness has found wide distribution as a repair material for tubeless tires.
With this harness, you can carry out repairs in any conditions: on a city street or on the side of a country road. It is a strip of high-strength nylon, which is richly impregnated with high-quality rubber-based adhesive. Such harnesses are supplied to the domestic market by many manufacturers, they have certain differences in technical characteristics and cost. But all cord harnesses are installed according to the same type of scheme: nine0003
First of all, they find the place of damage and mark it with wax crayon or another marker.
Remove the item that damaged the tire if it is stuck in the cord.
Then you should check the tire pressure, it should not fall below 0.5 atmospheres.
Take a spiral awl and use it to determine at what angle the tire is damaged. nine0003
Apply vulcanizing glue to the awl.
Using the awl inserted into the puncture, coat the puncture site with glue in the most thorough way, for which you need to rotate the tool lubricated with it clockwise.
Perform this action three times - lubricate the awl and insert it into the puncture, then leave the tool in the cord for the time being.
Insert the tourniquet into a special needle, focusing on the center.
On both sides, cover the surface of the tourniquet with vulcanizing glue.
Remove the helical awl from the tire where you left it at the puncture site.
nine0114Install a pen with a needle and a tourniquet placed inside into the puncture.
By pressing the handle, install the needle with the tourniquet into the puncture, advancing to the stop at a given angle.
Remove the pen with the needle from the puncture site without rotating it.
Carefully cut off the parts of the tourniquet sticking out on the surface.
nine0003
Then you need to determine how tight the tire is repaired. This can be done with the help of a special liquid, which is used to determine the puncture site. If, after applying such a liquid, no air bubbles appear, then the tire is temporarily repaired and can be used further. If air bubbles appear, try installing an additional tourniquet in the place of damage to the tire.
This method of temporary repair is inexpensive, but it has proven its effectiveness more than once. A tire repaired in this way without repair will serve you for a long time - up to 6 months. nine0003
A rubber harness costs more than cord, but it is also more reliable. They install it in much the same way as the cord one, but there are still some differences. For example, when installing a rubber band, do not use an awl in the form of a rasp, since it can damage the rubber band during installation. In addition, the rubber band must be mounted on the adhesive specified by the manufacturer in the instructions for the repair kit.

In this case, an anchor is a special type of bundle, one end of which ends with a small patch. The anchor is installed in the same way as other types of harnesses, but in addition, it glues the puncture site with an internal patch. To do this, the tourniquet is pushed inward, and then pulled a little in the opposite direction. Anchor can only be installed using a special cutter with a diameter of 6 mm. It is purchased separately from the set. But your efforts will surely be crowned with success, because the anchor is considered the most reliable option for repairing a tubeless tire with a harness. But with the help of harnesses, you can not repair side punctures. And in any case, even if the repair is successful, it is necessary in the coming days to choose the time to visit the tire service. Remember that prolonged use of the harness will cause irreversible damage to the tubeless tire.
And until the problem is fixed, constantly monitor tire pressure. nine0003
The second option for repairing tubeless tires involves the use of sealant. This option cannot be called optimal, but it has become widespread, since tire repair in this way is carried out very quickly, literally in a matter of minutes. And the result of its implementation is guaranteed to allow you to get to the intended purpose of the trip, without first stopping by the tire service you met along the way.
The sealant is very easy to apply. In this case, it is not necessary to remove a nail or other object from the cord, due to which the tire was damaged. Simply attach a bottle filled with sealant to the valve on the rim of the wheel and see that the contents of the bottle are pumped into the wheel. Keep in mind that repairing a tire with sealant will significantly disrupt the balance, so choose a moderate speed. But on the other hand, repairs with the help of a sealant are easy, simple and very fast.
