ABSTRACT:
A central tire inflation and deflation system which quickly inflates or deflates tires to any one of a plurality of pressures selected by the vehicle operator. Inflation pressure is greater than the pressure to which the tires are to be inflated. The system uses a tire valve which deflates the tires when a pressure less than the instantaneous tire pressure but greater than a minimum value is applied to the valve. Pressure on rotary seals which connect the tires to the system is relieved when the system is not operating.
