Maximum tire pressure limit for the 3ZERO MOTO is 50 psi (3.4 bar).
As for tire pressure recommendations, if you are accumulating dents on the sidewalls of your current aluminum box section rims, we recommend maintaining the pressure you are currently running with the 3ZERO MOTO. If you aren’t denting your rims, we recommend trying a lower tire pressure than you would ride with aluminum box section wheels (typically 2-3psi less). This way you can get the greatest ride performance and traction benefits provided by the 3ZERO MOTO rim design. Using the integrated Quarq TyreWiz tire pressure monitoring sensor is a great way to accurately dial in the best tire pressure for you.
