1. A tire pressure control system for a tire mounted to a wheel, comprising:

  • a servo system mounted to the wheel and including a servo mechanically connected to a vent valve in fluid communication with gas inside the tire, the vent valve adapted for bleeding gas out of the tire and into the ambient atmosphere, a pressure sensor in fluid communication with the gas inside the tire, and a control circuit electrically connected to the servo and pressure sensor, the control circuit further including a signal receiving means and a memory for storing a commanded pressure signal, the control circuit actuating the servo to open the vent valve when the pressure sensor indicates a tire pressure of greater than the commanded pressure; and

    a master control unit adapted to transfer the commanded pressure signal to the control circuit through a transmission means.
