Tips and Tricks for Tubeless Tires
A tire must be tubeless-compatible to work without a tube. A tubeless tire will be clearly marked as such on the tire sidewall unless you are using a conversion kit.
Seat the tire beads on both sides of the inflation valve to prevent gaps that allow air to escape
Rest the tire beads uniformly in the center channel of the rim. Beads must not fold or deform prior to tire inflation. Any odd deformation will allow air to escape during inflation
Eliminate all gaps between the tire bead and the rim strip that may allow air to leak. If a gap is suspected, pull the tire towards the rim opposite from the gap. This will pull the bead with the gap into a sealed position on the rim strip
Seat the inflation valve against the rim strip or air will escape around it during inflation. Secure the valve retaining nut by hand only to ensure easy removal
When possible, inflate a tubeless tire initially with a larger hand pump, floor pump or CO2 cartridge. The low air flow rate in some small hand pumps will not initially inflate a tubeless tire
If none of the above has solved the problem, the tire may be damaged. Substitute a tire that is known to work and try again. If it inflates, the original tire is probably damaged or defective and must be replaced
The tire inflates initially, but then loses air quickly
*If air comes out the valve hole of the rim, it does not necessarily indicate a problem with the valve
A tire must be tubeless-compatible to work without a tube. A tubeless tire will be clearly marked as such on the tire sidewall unless you are converting it.
New tires that have never been seated on a rim may be easier to setup tubeless after putting a tube in the tire. This helps to remove folds in the tire’s form from packaging. These folds can often cause air leaks. Usually a night with a tube will shape the tire enough that it can be seated tubeless on a wheel.
Clean the rim strip before assembly and inflation. Dirt on the rim strip could cause a leak
Look for cuts, tears, or gouges in the rim strip that could cause a leak. Use care when mounting or removing a tire so as not to damage the rim strip. If a rim strip is damaged, it must be replaced to prevent damage to the wheel tire or yourself!
Seat the inflation valve against the rim strip or air will escape around it. Secure the valve retaining nut by hand only to ensure easy removal
Inflate the tire to between 50 and 60 psi to properly seat the tire beads. (Note: Some tires may not require a full 50-60 psi to seat properly)
An installed tubeless tire fits too tightly to be removed
Push one tire bead at a time into the rim’s center channel. Beginning at the valve, pull one of the beads up and over the side of the rim. Extreme care should be exercised if a tire tool is used in this process. Excessive force on the tool could damage the rim strip or tire bead.
