There are two main methods for adding sealant to the tire:
This method requires a measuring cup. An air compressor is highly recommended.
This method requires a valve with a removable valve core, a syringe, and an air compressor.

In general, punctures in tubeless tires cannot be repaired. Punctures in UST tubeless tires, and other tubeless tires with a butyl inner lining, can potentially be repaired using a vulcanizing patch kit such as the VP-1.
It is not recommended that you attempt to use other types of patches, or attempt to repair other types of tubeless tires.
See Inner Tube Repair for instructions on using a vulcanizing patch kit.
Jim’s Tech Talk
By Jim Langley
In several recent columns like this one. I’ve offered tool tips and ideas for a common and extremely frustrating issue with some tubeless tire and tubeless-ready rim combinations.
The issue is that, when the tires are installed, the tire beads become locked onto the rim. There are shelves on each side of the rim designed to lock and hold the tire beads in place. The problem is that they hold too well and when it comes time to remove a tubeless tire locked on like this, it can be monumentally difficult to remove.
If you carry a tubeless plug patch kit, such as the ones by Dynaplug (see my recent review) you may never have to remove a tubeless tire to fix a flat on a ride.
But you’ll still run into the issue when it comes time to replace the tire, if you work on your own bike and have tubeless road tires and rims with locking beads.
Even if you have tire levers that work well on other tires, they usually won’t work for removing the locked on tubeless tires you can run into. The problem with standard tire levers is their tips are too thick to fit between the tire bead and the rim. You can try to jam it in-between but the mechanical advantage of the bead lock designed to not let go no matter what, prevents getting anything too thick between the rim and tire. There isn’t enough space, either.
If you’re lucky, instead of using a tire lever, you can push on the sides of the tire with your hands to try to shove the bead at one spot off the rim shelf there. If you try spots every few inches around both sides of the rim, you might find one spot that releases. And if so, that one free spot will create the slack needed to get the tire off all the way around on that one side.
Then you just have to repeat the process on the other side to unlock that bead and remove the tire.
As I wrote in previous Tech Talks about stubborn locked on tubeless tires, I’ve been trying to invent a tool that both fits in-between the tubeless bead and the rim and also has a pinching action to push the bead off the rim. I have not had much success – lots of ideas, but nothing I thought would work with all tires and rim types I would like to use it on (for road and mountain tubeless tires – MTB tires can be much worse than road).
Finally, the other day while fighting to remove a locked on tubeless tire, I had a eureka moment. This tire was even worse than a typical locked on tubeless because I had put a new tube in to fix a flat. The sealant in the tire stuck to the tube gluing it inside the tire and this made it even more difficult to push the tire beads off the rim.
Realizing I couldn’t force this tire off with my hands – or any of the regular bicycle tire tools in my shop – and I have about everything ever made, it dawned on me that I might have a much more basic tool to do the trick.
The tool that worked the magic was a good old fashioned putty knife. Here are some photos so you can see the type. With its oversize handle you have a great grip for forcing the tool in between the tire and rim. You have to work at it a bit with the goal of getting the entire width of the blade resting on the rim.
Once the tool’s blade is fully down in between the tire and rim, you can use the tool as a lever and also twist it to get its stiff wide blade to push the tire bead off the rim shelf. You use the tool carefully so as not to jab any sharp edges into the tire or rim. You’re just trying to get the tire bead to move toward the center of the rim.
It took a few tries to free the tire, but the putty knife worked well. I had to be sure to keep it down against the rim and focus on moving the tire not in any way scratching or poking the rim or tire.
If you try this with a new putty knife, you want one that has a blade stiff enough not to bend.
That way using it as a lever or twisting it to push the tire the blade will be strong enough to have the desired effect. If the new blade has any sharp edges, be sure to dull them with a file or piece of sandpaper, etc.
I hope this tool tip helps you with locked on tubeless tires. If you give it a try, please comment and let everyone know how it worked. And, please comment with your favorite tools for removing locked on tubeless tires.

Situations when you have to change the tire yourself are rare. As a rule, these are:
The disassembly process is the removal of rubber from the disk. Each driver should know how this is done at home in order to quickly solve the problem without resorting to the services of qualified specialists.

If you are interested in how to disassemble the wheel yourself, remember that you will not need special professional equipment, but not every tool at hand will do. For example, using a hammer and pry bar can damage the tire and rim.
A simple wheel disassembly kitTo remove a tubeless tire, you need to prepare:
After removing the tire, it is important to wipe the rim dry so that it does not interfere with the beading process.
nine0006 An important rule that must be taken into account: the removal of the tire from the disk should begin from the place that is located opposite the spool, and then move along the rim. Using this method, you can remove the tire from the disk within half an hour. nine0003
To separate these elements from each other, it is better to use a prepared steel angle. The rounded edge will avoid tire and rim damage. It should be driven in so that there is a space between the tire and the wheel. After mounting blades, disassembly is performed.
This allows for precise operation without damaging the camera. It is removed only after the tire is completely removed on one side.
At the end of the process, the driver will need to place a new tire and repeat all the steps in reverse order. nine0003
Due to the lack of a chamber in the wheel, the tire hermetically sits on the rim and is filled with air. In fact, she turns into a camera. The advantage of such tires is the slow process of pressure loss, which is characteristic of accidental punctures.
There are a lot of these wheels on the market today. This design allows you to fully control the car in this situation, without losing control, and provides an opportunity to get to the nearest tire shop or home. nine0003 Skill is required to disassemble the wheel on the machine and not tear the rubber. All you need is a desire and a minimal set of tools at hand. The most difficult part of the process is pumping the wheel with air. This procedure is required. The tire needs to be in place. This requires a large volume of air, which is unlikely to be able to provide a mechanical pump or a car compressor.

The easiest way is to use ether and 10–20 g of gasoline. It is important to use a moderate amount of fuel for the process to be safe. When igniting ether and gasoline, the tire automatically jumps onto the hump wheel.
Important! The wheel must be inflated in parallel with the indicated process so that the tire does not come off.
With a tire changer, it is much easier to carry out all the necessary actions. In this case, a minimum number of tools is required. nine0003 Installing a tire on a hump wheel
If the beading is incorrect, the machine can tear the rubber or damage the rim. This must be taken into account when taking any action.
Using the tire changer, it is much easier not only to assemble the wheel, but also to inflate the tubeless tyre. A large volume of compressed air supplied at a fast pace will allow you to easily install the tire on the hump. This method is more correct when beading wheels, as it minimizes the risk of tire and rim damage, and also allows balancing after completion of work.
It is from this stage that the comfort of using the car will depend. nine0003
Before dismantling a car wheel correctly, you need to prepare the appropriate tools and materials. The process itself is simple if you follow all the steps step by step:
Since the problem can catch any driver on the road, it is important to carry with you the minimum improvised kit necessary for the described manipulations. On the road, there may simply not be a tire fitting and specialists nearby who could help. nine0003

Ask a question
Buy tires in Sochi - catalog with prices. nine0002 Modern drivers rarely remove and put tires on wheels on their own. Most owners of cars and trucks turn to tire shops for wheel repair. But sometimes there are emergency situations when it is necessary to disassemble a tubeless wheel. For example, you need to replace a damaged tire, but there is no service nearby. Next, we will tell you how to remove and install rubber, and then pump it up without a compressor. The first method is the most common. It is rooted in the last century, but continues to be popular with many truck drivers.
Quite often, tires sit on rims for years. During this time, the tire bead "tightly" sticks to the rim, especially on tubeless wheels. It is impossible to separate the rubber from the disc. Then you have to use a sledgehammer and a wedge (a thick steel corner, 10 cm wide). By tapping the tire around the perimeter, it is guaranteed to separate from the rim. In the process, care must be taken and accuracy, as you can strike a strong blow to the disk. nine0003
The hammerless method is more humane and is suitable if a sledgehammer and a wedge are not available. Sometimes it's enough to use your own weight. Just jump on the sidewall of the tire and it will come off. If not, then the mass of the car is used, acting as a press. The wheel is placed with the edge of the tire under a pre-jacked car. Then the car is lowered onto the tire, through the gasket (a piece of board), and detachment occurs. In other situations, a rack jack will help. It is enough to rest his heel in rubber, and tie the lift with wire to the bolt hole, and then start rotating.

!It is not possible to drive forward and backward on an empty wheel for disassembly. Such an action can ruin the tire carcass, after which the master will not be able to balance it!
Preparatory step
Before dismantling a light tire from a rim at home, it is necessary to put the car on a level ground, remove the wheel and prepare the tool. For repairs you will need: assembly tool (1-2 pcs.), a balloon wrench with a wide spatula, a large hammer, a piece of board, a rag made of dense matter, WD-40 grease or kerosene, acetone, vinegar 9%. If the bead sticks to the rim, it is recommended to fill the compound with one of the listed liquids and leave it for decarbonization for 12-24 hours.
After the sticky rubber has stood with liquid, you can try to separate it from the disk. First, stand on the sidewall with your feet and jump. If nothing happens, then tap the tire around the perimeter with a sledgehammer, through a piece of board.
A gap should appear. Then:
It is highly recommended to inspect the tool before use. It should not have burrs and riveted areas. Sharp bumps can severely scratch the rim enamel. If there are such defects, then they should be turned with a file. For disassembly, it is highly not recommended to use nail pullers and crowbars, they can tear the tire bead. nine0003
Assembling a tubeless tire is easy. It is enough to act in the reverse order, but first coat the rubber sides with soapy water. The real difficulties arise when it comes to the last act - pumping up the wheel.
