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!

Everyone loves to ride a bike. Well, almost everything. And the head of the metropolitan traffic police, Dmitry Korzyuk, rides it, and the founder of the Internet portal TUT.BY, Yuri Zisser. But will cyclists be able to fix a two-wheeled vehicle if a wheel suddenly breaks on the road? Blogger Alexander Deshchenko decided to fill this gap.
A bicycle is a rather complex technique. And any technique tends to fail over time. I will try to enlighten those interested in common breakdowns, as well as throw in some repair ideas. nine0003
There are plenty of parts on the bike. Of course, it does not reach the tractor, but still it will take a couple of days for someone who decides to take care of studying the names and purposes of at least most of them.
Therefore, we will not deal with this, we will limit ourselves to the minimum that is necessary for successful and safe movement.
If your bike rides, the pedals turn without extraneous sounds, and the gears (if equipped) change easily and naturally, you can be envied. Seriously - as with people, there are no completely serviceable bicycles, there are underexamined ones. nine0003
The most common "disease" among new bikers is flat tires. Rubber is not completely sealed, and over time, tire pressure decreases. In addition, the cleanest city in the world does not let you relax, from time to time providing an excuse to practice bicycle repair.
If such a misfortune has overtaken you, do not panic - of all bicycle diseases, blown-out wheels are the easiest to "treat". If at home you found a flat tire during the second whole, try pumping up, maybe you just didn’t pump up the previous time. nine0003
By the way, pumps are cheap, portable and good, you can choose any two characteristics.
Personally, I always have an inexpensive portable (more precisely, portable, because it hangs on a frame) pump at hand, and at home there is a good stationary one. In principle, pumping wheels is also better in the mind. At the end of any, even the cheapest and Chinese tires, the working pressures for which this tire is designed are indicated. If you don’t pump enough, you run the risk of breaking through on any bend in the terrain. If you pump it over - you can simply burst, like Piglet's balloon in the famous cartoon. Although, of course, there is a pattern "pumped up less - it's softer to ride, pumped up more - it rolls better." nine0003
But back to the flat tire. If you pumped it up, and it went down again, then it’s bad business with him, not with you. But here, too, you should not be especially upset. It is quite possible that when the wheel is inflated with the naked ear, a whistle of air is heard, or even some foreign object sticks out, indicating the place of the puncture.
If the rupture is visible, you can pull out a piece of the chamber with a hole, glue it, put it back and do not even remove the wheel from the fork. In bike shops you can find a wonderful mobile kit for patching wheels, a small box is sold for little money, the lid of which is two plastic spatulas for disassembling the tire, and inside there is a number of patches, a tube of glue and a piece of sandpaper. nine0023
If you have an interest in cycling, I highly recommend it, the thing is simply irreplaceable. Of course, the set is more likely to be marching and will not help in difficult situations, however, most of the common punctures heal.
By the way, the patches from the kit are quite large in size, they can be additionally cut into several smaller pieces. It is very simple to seal the hole found on the camera - you clean the surface around it a little, smear it with glue and press the patch tightly. Usually they are made of "raw" rubber, so the main thing is to fix it correctly on the camera, carefully fill it back into the wheel and pump it up, and then under pressure it will flatten to almost zero thickness and implant like a native.
And finally, you can inspect the tire itself for cuts. nine0003

How to fix a bike puncture in 7 easy steps
Although you might think that repairing a puncture can be expensive, it is actually one of the cheapest auto repair services. The price usually ranges from 6 to 20 euros, although they are usually around 10 euros.
The regulations also state that the area that can be repaired must be within the drawing, more specifically the center area of the tread. In addition, any puncture larger than 6 mm in diameter cannot be repaired.
nine0003
A punctured tire can be repaired if:
The tire has a tread cut. The sharp object did not leave a large crack.
To apply bicycle patches, first use vulcanizing adhesive to seal the gap. Make sure you apply enough and wait a few minutes for the glue to dry. Position the patch so that it is fully attached to the tube. nine0003
The critical decision after applying the solution is to let the area dry for at least one or two hours, especially if it is hot and humid, because if we let it dry for just a few minutes and apply a patch, it will most likely dry. take longer or finish peeling early.
It usually takes 15 to 20 minutes to repair a puncture.
But the time will also depend on the complexion and the type of tire puncture. nine0003
You can pay attention to the sound to listen for the exit of air, and use your sense of touch until you notice a change. There are those who dip the wheel into a bucket of water to quickly find the puncture site by looking at which area the bubbles are coming out of. When you find the perforated part, mark it with an X.
The cost of the plaster is 50 pesos; vulcanized varies from 100 to 150 pesos. nine0003
Driving with a flat tire. Drive slower. Avoid driving faster than 24 to 32 mph (15 to 20 km/h) with a flat tire. You can cause irreparable damage to the metal wheel under the tire and even lose control of your vehicle.
What are vulcanized patches? If there is a small puncture or superficial cut that does not compromise the safety of the wheel and therefore the vehicle, a vulcanized patch can be used, a method that is more durable and cheaper than a complete wheel replacement. nine0003
When the nail is deeply embedded, it works like a plug and prevents uncontrolled air leakage. If you don't have a spare tire and need to drive to the nearest store, this annoying nail can save you the trouble. Just leave it where it is and drive slowly towards the vulcanizer.
Patch: This is the most common method recommended by professionals because it is a quality solution. After examining the tire, the specialist puts a mushroom-shaped patch on the inside of it, which hermetically closes the cut.
nine0003
Make. After you have been exposed to a needle stick or cut, wash the affected area with soap and water. If splashed into nose, mouth or skin, rinse with water. If such exposure occurs in the eyes, flush them with clean water, saline, or a sterile irrigator.
The presence of a lump or egg in the tire is a clear sign that the inner layers have suffered irreparable damage, it is the inner part of the tire, the radial structure that has undergone a rupture. The tire is supported by air or nitrogen pressure (better than the latter). nine0003
For bonding EPDM and natural rubber, a simple solution is to choose a special adhesive for bonding difficult rubber or rubbers, such as Permabond 105.
patch | Definition | Spanish Dictionary | RAE - ASALE.
1. tr. patch (‖ install patches).
Plugs are a quick fix to keep air from leaking out of a tire, but it's best to seal them to ensure a tight seal and safe repair. nine0003
It consists of a kit that you can find in auto accessory stores, it consists of a piece of rope with industrial adhesive that is added to a tire puncture with two simple tools, without using a jack or removing the tire.
Although some brands offer tires that promise to last around 10,000 km, in practice it is very likely that we will have to replace them when we get close to 3,500 km or about 3,200 km. nine0003
Insufficient tire pressure.
Too high pressure reduces tire grip; too low pressure allows the tube to pinch on impact (on a pothole, on a step), and rubbing the rubber against itself often causes holes in the tube.
The answer is simple. It's just a matter of physics. Bicycle tire pressure is reduced due to the composition of the air containing nitrogen and oxygen. Be aware that a flat tire is not always synonymous with a puncture. nine0003
Usually the best solution when it comes to repairing small tubes and tires. Meanwhile, tire vulcanization is carried out on those tires that require processing at high temperatures and constant pressure in order to connect the molecules of the repairman and the tire.
What is a vulcanizer? Basically, it consists of two heavy metal strips, which are placed one on each side of the pre-prepared joint and firmly held together. Each strip heats up and this combined application of heat and pressure completes the bond over time. nine0003
Alignment is the process of adjusting the steering, suspension and tires of a vehicle, while balancing is the adjustment of the vehicle's balance of power to prevent vibration and bouncing when making any turns.
Vulcanized hard rubber, sometimes sold under the brand names ebonite or vulcanite, is used to make hard objects such as bowling balls and saxophone mouthpieces. Uncured natural rubber is sticky, deforms easily when hot, and becomes brittle when cold. nine0003
A new tire tread can last up to 100,500 miles, but if the carcass is in good condition, you can potentially go up to 500 miles by vulcanizing it before you can't do it anymore.
Tire curing consists of heating the rubber and sulfur on the surface of the tire and applying pressure to either install a new tread band or repair tire damage. nine0003
- Insert file
This will require some force as you will have to push it through the steel straps. Insert it into the tire with a twisting motion. Once you've gone through the reamer, insert it into and out of the tire a few times to make a good hole for the plug.
According to tire manufacturers such as Michelin, the average is around one puncture every 50.000 km, however everyone knows a driver who has never had a puncture and a driver who loses air from his tires every two to three . nine0003
It usually takes about a year for a tire to lose its minimum safe pressure, but if our car has been exposed to extreme temperatures and the situation suddenly changes, the porosity can increase and lose more air than usual.
This is a patch with a lot of flexibility. The upper part has a layer of butyl rubber, hence the name of the extra-hermetic lining; They have excellent heat resistance and adhesion to cushion rubber, allowing us to hot vulcanize them. nine0003
The needle itself can cause tissue damage as some are large and can become blunt and break off after repeated use (fig.
1). Injections with commonly used needles create a much higher risk of injury and infection.
Although we think otherwise, a rear wheel puncture is more dangerous than a front one. It is easier to lose control of the car if the rear wheel blows than the front. An older tire is more prone to punctures and tears. nine0003
No, the typical egg on the side of a tire cannot be repaired. Moreover, this is one of the most dangerous damage that occurs in tires, as many users do not pay attention to it and continue to use the tire as it is, relying only on the condition of the tread.
When we hit our tire on the sides, be it pavement or any other element, the inner fibrous structure of the tire breaks down and allows the pressure to push that area outward and these chips form. nine0003
Place the patch sticky side down and apply a hot iron to the fabric, pressing down for about 30 seconds to bond the adhesive to the fabric.
