Home Features How to Plug and Repair a Tubeless Motorcycle Tire
Sacre bleu! The discovery we all dread, usually right before a ride. Don’t attempt to repair a severe gash or cut, or a puncture in the sidewall of the tire. Once you get the hole plugged, it’s off to your dealer for a new tire.Considering how bulletproof the rest of our motorcycles have become, it’s ironic that it only takes a little 1 ½-inch box nail in a tire to bring the whole show to a halt. We’re fortunate today that tubeless tire technology prevents intrusions by nails, screws and other foreign objects from becoming catastrophic blowouts. The object usually stays in the hole, the only place from which the tire can lose air, so it deflates more slowly than a puncture in a tire with a tube on an unsealed spoked wheel (which can lose air through all of the spoke nipples and even the tire bead).
But even if that pointy thing does stay put and flush with the tread surface, as it flexes back and forth in the carcass the tire will eventually deflate enough to become a problem. Hopefully you will have noticed its presence or even received a low tire-pressure warning before that happens.
Of course, if it doesn’t stay put or is large enough to stick out of the tire (like a 6-inch gutter nail — don’t ask), the tire will probably deflate rapidly enough to strand you by the roadside. Unless you’re lucky enough to be next to a motorcycle shop at the time, you’re going to need either a good roadside assistance plan or a tubeless tire repair kit. (We’ll cover tube-type tire roadside repairs in another installment).
Once you’re sure your glue isn’t dried out and you have a way to re-inflate the tire, pull the offending object out. You may need pliers if it’s really in there.Use the reamer in the kit to enlarge and clean the hole—this is where large T-handles make the job a lot easier.
Take some extra time if the tire has steel belts.Install a worm on the insertion tool — note that its tapered tip is split to allow the tool to pull free of the string once it’s well inside the hole.Put some rubber cement on the worm and a blob on the hole, too, and slowly insert the string in the hole about two-thirds of the way. If it falls inside the tire, just start over with a new string. Gently pull the insertion tool free, leaving the worm in the tire. Again, T-handles make this much easier.Use the knife in the plug kit or any sharp blade to cut the plug flush with the tread surface. Give it a few minutes to set up, inflate the tire and then spray some water or a soapy solution on the plug to make sure it’s holding air.
Here at Rider we’ve fixed enough tubeless punctures to appreciate that the most dependable tire repair kit you can carry uses rubber strings or “worms” for the plug that gets inserted into the tire, preferably the large red ones like those in the T-Handle Tubeless Tire Repair Kit from Stop & Go.
There are more convenient plug types, but the strings rarely let us down. If you’ve had good luck with liquid sealers, installed either pre- or post-puncture, more power to you — we often carry Slime for tube-type tires on bikes that have tubes in the hope of avoiding a roadside tire dismount. But we change bikes too often to make using the pre-installed sealers practical, and prefer to avoid irritating the mechanic who has to change a tubeless tire on a wheel full of messy sealer.

Repair kits that use string plugs often come with rubber cement, which — depending on the string type — may not be necessary to complete the repair, but at a minimum it acts as a lubricant to ease inserting the plug, and seems to help vulcanize the plug to the tire. It’s important to keep your glue supply fresh (preferably unopened), or you may find that it has dried out when you need it.
Stop & Go’s T-Handle Kit has everything you need to affect a solid repair. Just add pliers and something with which to inflate the tire (CO2 cartridges or a compressor).
Stop & Go also offers a plugging kit that uses special mushroom-shaped plugs that don’t require glue, and the pocket version doesn’t take up any more space than the T-Handle Kit, so we often carry both. A portable mini compressor beats the heck out of CO2 cartridges if you have the space. Stop & Go’s is small, inexpensive and has a built-in gauge.No matter what sort you use, any plug inserted from the outside should be considered a very temporary repair used to get you and your bike to the nearest replacement tire. Limit your speed per the plug kit instructions, and replace the tire as soon as possible. Special patch plugs inserted from the inside of a tubeless tire are certainly safer, but even if you can find someone who will install one for you, every tire manufacturer (and even those who sell patch plugs) recommend replacing the tire instead since it has to come off anyway.
The photos in this article cover the basic plugging process with rubber strings. Depending on the size of the hole, you may need more than one — I once used three in an ATV tire and it got me back to camp.
Getting a flat tire in the middle of a ride is a nightmare for every motorcycle rider. It gets even worse if you’re far from home and can’t spot a bike repair shop nearby. A flat tire doesn’t always need a new tire change.
Using a motorcycle tire repair kit, you can quickly fix your flat tire by the roadside and carry on with your journey. This guide will expand more on how to fix your flat motorcycle tire.

Now, if you get a flat tire on any of your motorcycle wheels, you should immediately and pull over to somewhere safe to fix the tire and get it back up in shape and running.
Don’t attempt to ride with a flat tire unless you want to experience handling problems or damage your motorcycle rim.
Assuming you already know that motorcycle tires are either tubeless or tube-type, you’ll need to check what type of tire you have.
This is because the procedure for fixing a flat tire is slightly different for the two types of tires.
If your bike comes with a tubeless type tire, then you’re lucky as the process of fixing it is much easier and quicker.
Let’s get into the details of how to fix your tubeless tire:
Find the punctureYou first need to identify the spot where the air if coming out from. Try listening for some hissing sound as the air comes out. Also, do a visual inspection to see if you can see the object that punched your bike.
You might also consider rolling your bike around to view your entire tire if the fenders are blocking you.
If everything else fails, try using soap and water on the tire surface. The leaking air will blow air bubbles, and there you have the hole!
Grab the reaming tool from your motorcycle tire repair kit and work it in the hole.
First, remove the object on your tire you identified in the previous step. Then, work the reaming in and out, side by side of the puncture hole. This helps clear the hole and reveal the size of hole you’ll be patching.
Once you have cleared the hole, don’t be in a rush to remove the reaming tool. Let it stay in place to prevent air from escaping from your tire.
You don’t want to be left with a completely flat tire that takes forever to pump up to the right pressure.
Go back to your tire repair kit and grab the insertion/plugging tool (the tool with an eyelet) and the plugging material.
Get the plugging material through the eyelet of the plugging tool, just like you’d thread a needle. Pull out the reaming tool from the tire puncture hole and immediately insert the plug. Be sure to push it in up to ¾ of the way. And then, in one smooth motion, yank it out.
Using a utility knife, trim the excess plugging material such that it appears flush with the tire tread.
Leave the patch for rough 10 minutes to enable the plugging material to set in and seal the hole better.
After the 10 minutes are over, you’ll need to inflate your tire to the recommended pressure to get it back up and running. Some kits also feature small CO2 cartridges that might contain enough air to inflate your tire.
If you have a hand pump with you, it’s even a better option for inflating your tire as there’s no fear of running out of air supply.
If the problematic tire has a tube, this is your part. Working on this type of tires is usually trickier and more time consuming as you’ll need to take the wheel off the bike and then take off the tire from the wheel to access the tube and fix it. You’ll also need a longer list of tools for this job.
With the still on your bike, you’d want to start by removing the object that caused the puncture hole and then completely deflate the tire (tube).
Afterward, you can remove the wheel from your bike set it somewhere you’ll work on it comfortably. Assuming you’re on the road, avoid working on it on hard surfaces as they can be too hard on the rim.
If you have a spare jacket or shirt with you, you can spread it on glass and lay the wheel on it. An area with grass will also be suitable for the wheel.
If you have a portable bead breaker with you, you’ll have an easy time breaking the bid of your tire in this step.
Pressing down the bead with your motorcycle boot heel can also help break it.
Immediately the bead pops, use tire iron to pry the tire over the lip of the rim. And as you do so, remember to employ the rim protectors to protect the rim.
Push down on the bead on the opposite side of your wheel with your heel to make it move the center of the tire as you deploy the tire iron. This enables you to pry your tire over the rim by moving hand in hand around the entire wheel until the bead on the opposite side pops.
NOTE: Be careful not to dig your tire irons too deep to the point of further punching the tube.
With the rim off, accessing the tube will now be easy. Pull off the tube and patch it using the motorcycle tire repair kit you have at hand.
After fixing the tube, re-inset the valve system into its place in the rim and consider slightly filling up the tube with the hand pump or CO2 cartridges provided in the repair kit.
Now start slipping the slightly inflated tube back into the rime with the help of iron while using another iron to hold down the tire. When the tire is finally on, put the wheel back onto your motorcycle and inflate it to the recommended pressure.
IMPORTANT: Unlike in the case of a tubeless tire, a tube-type should be replaced after the first puncture. This patching we have explained above is not to permanently fix it but to help you reach home or a repair shop where you can replace it with a new tube.
Final Verdict
Never get stuck in the middle of a trip again because of a flat tire.
Bookmark this post so that next time you get a flat tire while on the road, you can quickly refer to it to fix your flat wheel and get it back up and running.
Remember to always carry with you an emergency motorcycle tire repair kit, a hand pump, and other helpful tools we have mentioned in this guide. These will go a long way in helping you quickly fix flat tires and get going.
There is not always a way to call a tow truck, and driving on a flat tire, “chewing” the rubber and killing the rim is at least uncomfortable.
The very first replacement of rubber on a motorcycle or scooter gives reason to think - what is better in terms of quick repairs: tubeless ones that do not require wheel disassembly to eliminate a puncture, but leave the rider helpless if, along with damage, it “led” and flattened the edge of the disc? Or chambers - allowing sealing almost ring breaks (if only there were enough patches), but requiring the removal of rubber from the rim for this? The unequivocal answer is no.
Few classics, straights or tourers today remain "loyal" to tube rubber models: tubeless tires are lighter, softer, warm up and cool down faster thanks to simplified heat transfer. In sports, more precisely - enduro and motocross, chamber - on the contrary, prevail: only spoked wheels can "play", withstanding strong alternating loads during landings and impacts.
The nuance is that a tire with a chamber can be put on any spoked or cast disc, and a tubeless one can only be placed on a cast one, because only it can ensure tightness. Tube – can be installed in a tubeless tire as an emergency measure. In case of major damage to the sidewall, cracks or curvature of the edges of the rim, this will make it possible, after pumping up the wheel, to reach the nearest tire service (and there already - straightening, balancing and other maintenance according to the rules). True, for such a focus, it is advisable to take a camera with a face value one less than the diameter of the disk, otherwise it will create folds inside that will rub for a couple of hundred kilometers.
The resource of such a “treatment” is large - until the next puncture, like a new one.
It depends on the magnitude of the damage whether it will be possible to eliminate it on your own, or whether you will have to “surrender” to the motorized tow truck. In tubeless - holes up to 5–6 mm are patched, in chambers - as much as there is enough glue and patches, the main thing is the condition of the tire. To determine the extent of the disaster - find a place where you can safely stop without violating traffic rules (where it is prohibited - you will have to sacrifice tires and drive on).
If the wheel deflates slowly, and the object that pierced it is still inside, you can try to carefully drive to the tire shop. A completely deflated "pancake" will have to be resuscitated on the spot, or - remove the wheel and take it to the service.
To find a hole in a tubeless tire, if it is very thin and not immediately visible, the wheel must be pumped up, slowly pouring water - bubbles will go.
In place, tubeless tubes can be “harnessed”, or filled with sealant inside, without removing from the motorcycle.
With the second type of tires - more difficult. A torn balloon must be removed from the tire to detect a defect and seal. In a good way, the wheel must be removed from the motorcycle and disassembled on a clean, flat, hard base. Suppose such a “patch” can be provided even off-road, but how to remove the wheel on a motorcycle if it does not have a central stand? And shooting is not required. The motor must be carefully laid on its side, after making sure that the faucet is closed, gasoline does not flow out through the tank cap (antifreeze does not flow from the tank if the motor is “dropsy”), and removing the plastic or wardrobe trunk with fragile contents (if any).
You will have to unscrew the wheel from the motorcycle only if you need to replace the tire, or it is decided to patch the tubeless tube with a “fungus”. In the absence of a central stand, this will also have to be done on a lying bike, or - make this stand from improvised materials (bricks, stump, car jack), placing them under the crankcase protection from below, the central tube of the frame, the duplex jumper (but not under the plastic, itself engine crankcase or attachments!), under both footrests - if they are not folding, or - under the pendulum.
Before removing the rear wheel on a motorcycle, the front fork must be loaded with something, or an even higher lining is made.
In a motorcycle tire fitting shop, tubeless tubes are repaired by cold vulcanization. They are removed, disassembled, the puncture site is cleaned from the inside, degreased, lubricated with glue and a calibrated “fungus” patch is inserted into the hole from the inside. The fungus itself is a thin plate of rubber with a “leg” tube in the center. The leg - by the guide wire is dragged through the hole of the damage, and the "hat" seals it.
After half an hour - you can put the tire back. The reliability of such a repair is high, the patch does not cause a significant imbalance, the service life of a sealed tire does not decrease.
This method is also applicable on the road, the main thing is to have the necessary equipment and materials with you:
The fungus repair procedure does not require much experience. The main thing is to keep it clean, fully clean the place where the patch fits, let the glue dry slightly to a dull finish and press (roll) the surface of the fungus with high quality, expelling all the air between the layers. If necessary, you can degrease the place before gluing with gasoline, but without the rest of the above, it will not be possible to fully carry out repairs.
The compressor is sometimes replaced by a small cylinder of compressed air or carbon dioxide. Unlike a mechanical pump, it will immediately create a “throw” of pressure, pressing the tire beads against the rim flanges (in emergency cases, even a fire extinguisher was used to pump flat tubeless wheels). When connecting the compressor, start the bike's engine before you start inflating the tire - let it idle.
Otherwise, the motor can "land" the battery, and you will not start.
Manometer - needed for control. It is undesirable to pump over the repaired tire. It is recommended to "inflate" 0.2 atmospheres less than the nominal value. Inflating too little is also bad: a flat tire has a larger contact patch with the road, so the place of a fresh patch will deform more.
“Burning” a tubeless tube and sealing its internal cavity through a nipple are quick, simple methods that do not require special skills. To repair the damage, you only need the materials themselves, and how to pump up the wheel.
Now in Moscow, and not only, 6-5 varieties of cans with a sealant are sold - a quickly hardening "liquid rubber", with a volume of 800 to 250 ml.
Applying "Anti-Puncture" is simple: put a tube with a fitting on the nipple of the camera, turn the can over, and hold the button according to the instructions.
Then - pump up the wheel, cleaning the nipple from the foam, roll it, making a full turn to distribute it.
The sealant is blown out with air into the puncture hole and clogs it, solidifying. After 20 minutes - you can go. Reliability of repair is high. Resource - until the next puncture.
If you have a compressor, start immediately pumping up the wheel, so it will be easier to work with a puncture, insert a patch, and it will swell faster.
Procedure:
You can go in 5 minutes, you just need to make sure that it doesn’t descend anywhere else.
Outwardly identical, repair kits for harnessing wheels can differ in price by almost half. This variation is explained by different configurations - one will have only three items, the other - six or seven.
A complete tubeless tire repair kit contains:
Regardless of the cost, you need to choose a kit in which the harnesses will be reinforced, and the awl - with a deep spiral winding (notch), and not a “needle file”.
Inserting a flagellum is sometimes easier with a regular thin screwdriver. If there is no glue in the kit, or it has dried up, the flagellum is moistened with gasoline.
At motorcycle service stations and car services, holes in the chambers are closed by hot vulcanization: a layer of raw rubber is applied to the cleaned, fat-free puncture site and, after squeezing it well, it is heated with a special “iron”. Iron - burns, layers - are fused into a single whole. Reliability of repair is high. The resource will be almost like a new one.
Cold vulcanization (patching) - used if the workshop is not equipped with a vulcanizer. In this case, the quality of the service and the reliability of the repair will depend on the accuracy of the master. For the convenience of gluing, the camera is completely removed in the service, but, I repeat, this is not necessary. It can be repaired on the spot in the same way (there are no other options except for replacing the camera), but without removing it from the motorcycle.
This can only be done if you have two metal mounting blades. At least one, the second can be replaced with another flat tool. You can still disassemble the wheel with a wide screwdriver and a “family” key wrapped with electrical tape. But this is only as a last resort, otherwise you can damage the cord.
Sequence of work:
Let the glue dry for a minute. The fencing must be carried out twice as carefully and more slowly than dismantling, lubricate the side with water or soap, “help” more with your hands, otherwise there is a risk of picking up the edge of the chamber with a spatula and tearing it.
Important! If the wheels of the motorcycle are equipped with tow bars - before pressing the tire bead from the rim, you need to loosen this tow bar! But do not unscrew the nut completely, do not disassemble to the end.
A standard “first aid kit” (a set for repairing classic motor rubber) contains only patches and glue, so it is advisable to supplement it yourself with a piece of “skin” or a needle file. You can degrease with gasoline, or apply a little glue first and wipe off immediately, rolling up the dust with it.
Now there is no shortage of specialized motorcycle workshops not only in Moscow - in all major cities there are motorcycle helpers who help motorcyclists directly on the track, or tow to where you can quickly change the camera, or patch the tubeless correctly, so that there is no trace left. Where there is a guarantee.
Self-replacement of a tire on a motorcycle requires a certain physical condition, and for the first time - a “kilometer of nerves”.
At the service station, instead of you, automation will “sweat”, which will not lock up the board and will not scratch the disc coating with a spatula. The main thing is to do it quickly (if you need to go urgently, the price sometimes does not matter).
Repair at the service - may be the only possible one if, due to driving on a flat tire, the tire nipple is turned and torn off. Especially if he flew off and got lost, but there is no spare. In mototiremontazhke - there is always a set of consumables for any wheel diameter. In the same place, in extreme cases, you can buy a new tire, or a used dokatka.
In addition to the patch, for normal operation of the wheel, balancing must be ensured. This is generally a useful procedure during any change of rubber, otherwise if there is a strong imbalance, the wheel bearing will inevitably break due to vibrations, and the hands will quickly get tired and “buzz” after long rides.
The first couple of tens of kilometers - do not drive, go at the speed of the flow.
Stop, check for a flat tire. If the patch is not of high quality, it will manifest itself almost immediately. Parking will tell about the long-term perspective: if the cylinder has not lost volume in the first day or two, then everything is in order, you can drive as before.
Knowing what to do if a flat tire is on the road is important not only “for yourself”. To help a newbie or a fragile girl is to earn an important “plus in karma”, which will later return at the right moment. But, I hope, this knowledge will be useful to you only in theory. Good luck on the roads, no nail, no wand!
The motorcycle gives a feeling of freedom, allowing you to discover new routes. However, in reality, this freedom can turn into a trap in an instant if you are unlucky enough to puncture a tire somewhere in the middle of the road. The feeling of annoyance will be ten times stronger if there is no way to fix a punctured wheel. At this point, it remains only to hope for cellular communication and help from other drivers on the road.
Therefore, consider the basic recommendations for repairing a motorcycle tire on the road.
Always keep a rubber band or tire repair insert in the trunk. This simple tool will add peace of mind on the road. It will be much better if you learn how to use it in advance. You don't want to be the guy who has the right tool but lacks the skills to fix a problem, even something as simple as fixing a tire, do you?
The repair technology for tube and tubeless tires is different, but both types are subject to restoration (at least to such a state as to get home). Repairing a tubeless tire is easier. Repairing a tubed tire requires removing the wheel, removing the tire, and removing the tube to install the patch.
So you run over a nail, screw, glass, or that damned sharp stone and punctured a motorcycle tire. If the object that caused the damage is still in the rubber, the first step is to remove it. Pliers are great for this.
Therefore, you should always keep this tool in the trunk: with it, you need to grab an object sticking out of the tire. Try to pull it out along the same path that it entered the tire so that the puncture does not increase and become torn.
After removing the object, clean the edges of the pierced hole. To do this, the repair kit must have a special tool - a tool for cleaning holes. All debris and rough edges must be removed to create a surface for patching.
Then you need to install a patch. Different kits offer different types of patches, so you should read the kit's manual to complete this step correctly. However, there are two main types of patches: long cord patches and fungus patches. Some kits may include adhesive to bond the patch to the tire rubber.
Patches or cord inserts are supplied with an awl for installation. It is necessary to bend the cord in half, and thread one half into the tool. This is necessary for a tight fit of the material.
Next, bring the cord into the hole until it protrudes above the tire by about 1 centimeter. Then you can pull it out of the awl and put the tool aside. Take a knife and cut off the excess patch material by about 0.5 centimeter.
Fungus patches (plug and play type) require the use of a special tool for installation. Again, you must follow the instructions for the specific repair kit. Then stretch the patch material with pliers. When the puncture is closed, you can cut the patch over the tire.
After installing the patch, the tire needs to be inflated. For repairs on the road, you will need either a 12V electric compressor that can be connected to the motorcycle's electrical system, or a CO 2 tank. Carrying a compressor with you is not always convenient. A more compact and more portable option is to use the small cans of CO 2 in combination with the tire inflator. This is the fastest way to inflate tires on the road.
If possible, apply some soapy water to the patch to make sure it is airtight.
If there is a leak, you will see tiny air bubbles around the repaired area.
On-road retreading of tube tires is a more labor-intensive process. If your motorcycle is equipped with such tires, then you will need a few more tools to repair them. In most models, you will have to remove and disassemble the wheel in order to get to the camera. The vehicle owner's manual should describe how to do this and what tools to pack in your luggage. In addition, you will need a tire removal tool. It makes the job easier.
Once the inner tube has been removed from the wheel, the remaining air must be completely bled out. The next step is to prepare the camera for patching. The repair kit should include a special scraper to roughen the surface around the punctured hole. This treatment is necessary to ensure adhesion of the patch to the chamber material.
After completing the preparation, you can start installing the patch. Follow the instructions in the repair kit manual.
