1. A tire pressure management system for use on an axle having a first tire and a second tire mounted thereto, the axle being mounted to an air suspension comprising a first air bag mounted to the axle and a second air bag mounted to the axle, the system comprising:

  • an air pressure supply sealingly connected to the first tire and to the second tire so as to allow sealed and substantially continuous communication of pressurized air between the air pressure supply and the first tire and between the air pressure supply and the second tire;

    an electronic pressure regulator situated between and in sealed fluid communication with the air pressure supply and the first tire and the second tire, the pressure regulator comprising an electronically-adjustable pressure setting to regulate the pressure of air passing therethrough; and

    a first pressure sensor disposed so as to sense the air pressure in the first air bag, the first pressure sensor capable of providing a first signal indicating the air pressure in the first air bag;

    wherein the electronic pressure regulator comprises a processor configured to receive the first signal, determine the load carried by the axle based on the first signal, and send a pressure adjustment signal to the regulator to automatically adjust the regulator air pressure setting based on the pressure adjustment signal in order to provide substantially continuous communication of pressurized air at an adjusted air pressure between the air pressure supply and the first tire and between the air pressure supply and the second tire.
