ok i put gc xtreme 1/2" valves in my truck a few months ago before i parked it and took it out for a ride today and im running 240 psi. at 170 or so it is fine but somewhere between 170 and 240 it lifts the rear by itself and it is both sides and i dont get it. im running 8 valves so what are the chances both valves leaking are the rear fills?
