Tubeless technology has potential advantages over crude but effective tubes, but it’s not without its problems. The most common complaint is air loss. For many users, tubeless tires Seems to drop pressure much faster than its tubular counterparts.
While any tire, especially lightweight tires with thinner, more breathable sidewalls, will lose air over time, if the leaks are rapid or regular, there may be an issue that needs to be addressed.
Tubeless tires require a number of compatible components to complete the system – tires, rims, rim tape, valves and sealants. Everything needs to be in good working order; when it comes to tire pressure loss, any one, or really a combination of them, could be the culprit.

your tire Tubeless compatibility is required for the system to work properly. If not, you won’t get an airtight seal due to the bead diameter and sidewall construction. Maybe it’s obvious, but if your tire pressure drops quickly after installation, it’s worth checking tire compatibility.
Assume your tire Compatible with tubeless tubes, it may be the position of the tires that is causing the problem. Start by inspecting the rim for damage, looking for any dents or defects. If a new tire is flat, it may be because the bead that was folded before installation was not fully straightened to ensure proper seating. Installing an inner tube and leaving it for a day or two should solve the problem.
If you’re not sure your tubeless tires are mounted correctly, it’s wise to use a dedicated compressor; it’s still the best way to mount tubeless tires and allows you to do so without having to over-inflate the tire, which can damage it Tape and rims.
Rim tape

While some tubeless rim beds don’t have spoke access holes, many tubeless-ready options do and require tubeless rim tape to cover the holes to prevent any air from entering the rim cavity. If your tubeless tire is flat, it may be because the rim tape was installed incorrectly or moved after installation.

Caution is required when installing tubeless tape. It needs to be installed to a clean edge as dirt and dust will prevent the tape from sticking properly. You’ll also need to apply a little pressure in a similar manner to wrapping strip tape to make sure it’s seated well into the rim bead – if your tape has bubbles and wrinkles, then this could be the culprit. As before, installing an inner tube and leaving it overnight can also help smooth out these wrinkles. You’ll also want to match the tape to the inside width of the rim; this may mean a double wrap or a single wrap with wider tape.
Tubeless rim tape can come off during tire installation or replacement, usually when tire levers are used excessively during the process. If you have a flat tire, check the tape for damage.
valve

The next stop is the valve. Tubeless setup requires dedicated tubeless valve And its outer ring needs to be closed to stop any air from escaping. If your valve collar is too tight, you need to check how the valve is installed; the rubber “wedge” that rests against the rim needs to be pushed down, rather than sitting loosely above the rim. At this point, it’s also worth checking the edge tape around the valve holes for damage. The tape may split around the hole, especially if the valve is accidentally inserted; it is best to slowly turn the valve into the hole rather than pushing it into the hole, as this can cause the hole in the tape to enlarge .
sealant
Adding fresh sealant from time to time is necessary to prevent leaks
If all of the above checks fail, air loss may be due to sealant. Or rather the lack thereof.
If you haven’t added sealant in a while, it may be because it has dried, preventing it from sealing any punctures in the tire. By turning the steering wheel, you should be able to determine if this is the case.
If you recently switched to tubeless tires and the sealant is new, you may want to check that you’ve added enough sealant; the tire and sealant manufacturer will specify the amount to use based on your tire selection.
