1. A tire management system for a truck or trailer comprising an axle having a first tire and a second tire mounted thereto, the system comprising, an air pressure supply connected to the first tire and to the second tire so as to allow sealed communication of pressurized air between the air pressure supply and the first tire; a first pilot-operated check valve in sealed fluid communication with the air pressure supply and with the first tire; a second pilot-operated check valve in sealed fluid communication with the air pressure supply and with the second tire; the first and second pilot-operated check valves each being configured to allow air to flow only from the air pressure supply to the first tire and the second tire, respectively, when not activated, and to allow air to flow between the first tire and second tire and the air pressure supply to maintain substantially equalized pressures in the first tire and second tire when activated, the first and second pilot-operated check valves being further configured to remain substantially continuously activated while an ignition switch of the truck is activated.
