For tubeless set-up, it is recommended to inflate your tires to 3 bar / 43PSI once during assembly. This way the tire can pop into the rim. As a general guideline, you should inflate your tires to about 2 bar / 29PSI. Of course, the ideal air pressure varies depending on the rider's weight, the type of tire and the intended use. Please always adhere to the maximum air pressure recommended by the tire and rim manufacturer.
