1. A tire inflation system, comprising:

  • an air supply source in selective fluid communication with a tire;

    a pneumatic conduit extending between said air supply source and said tire to provide said fluid communication;

    a first valve in fluid communication with said pneumatic conduit, said first valve including an open position and a closed position, whereby air passes from said air supply source through a first portion of said pneumatic conduit to the first valve, and when said first valve is in the open position, air passes through the first valve to a second portion of said pneumatic conduit;

    a second valve disposed between said second portion of said pneumatic conduit and a third portion of the pneumatic conduit, said second valve being in fluid communication with said pneumatic conduit, the second valve including an open position, a closed position, a first channel, and a second channel, whereby when said first channel aligns with the second and third portions of the pneumatic conduit when the second valve is in said open position, air passes between said second and third portions of said pneumatic conduit via said second valve, and when said second channel aligns with the third portion of the pneumatic conduit when said second valve is in said closed position, air vents from said third portion of said pneumatic conduit to atmosphere via the second valve;

    a rotary union in fluid communication with said third portion of said pneumatic conduit adjacent said tire;

    a first pressure indicator in fluid communication with said first portion of said pneumatic conduit to indicate an air pressure in the first portion of the pneumatic conduit; and

    a second pressure indicator in fluid communication with said third portion of said pneumatic conduit to indicate an air pressure in the third portion of the pneumatic conduit.
