Fixing a Puncture in a Tubeless Tire

Any experienced driver knows that a puncture in a tubeless tire isn't always easy to find. If you can't see the head of the nail or screw, locating the leak can take a long time. But once you do find the foreign object, don't rush to pull it out. As long as it's still in place, the tire won't lose air quickly. Of course, if you top up the tire from time to time, you can keep driving on it for a while. The problem is that each time you inflate the tire, the object rubs against the steel wires of the cord and damages them. That's why you shouldn't put off the repair. It's better to pull out the nail right away and seal the puncture. 

To find a puncture in a tubeless tire quickly, wet the tire slightly with soapy water, and bubbles will show you where the air is escaping. The main advantage of a tubeless tire is that you can plug a puncture without removing the tire from the rim, using a sealing cord (tire plug strip). The most reliable option is a rubber plug with an adhesive coating. First, clean the area around the puncture of dirt. Then coat the plug with cement, which will react with the adhesive layer. Note that it's best to use the cement recommended by the plug manufacturer. Also avoid using a rasp-style reaming tool. It's best to use not a straight insertion tool, but a special tool with a side opening. 

Keep in mind that a plug is not meant for repairing sidewalls. So at the first opportunity, take the tire to a shop, or properly repair it yourself from the inside with a patch or a mushroom-style plug-patch.
