Kevin B is off the scale
Default

They are adjustable from 20 psi. to 5 psi. You set them with a allen wrench from the inside. After you set them you just screw them on and it deflates the tire to the set point . very cool things to have . I usually air down anywhere from 25 to 14 psi. depending on terrain.
