Inaccurate. very inconsistent. Flatten tires completely. It's garbage. None of the four works properly. I have a schrader coupler hooked up to my air compressor. I can check all my pressure sensors. I can even use it to adjust the pressure of the dump valves. but the second you put them on the truck. they bleed slowly. and well below the 20psi they were set for. when I decided to undress her. My air gauge read 5psi. I don't use beadlocks. This pressure is a disaster. Did I mention THEY ARE STILL DEFLATED when I took them off to check the pressure?
