1. A tire inflation system for a vehicle having an outboard tire mounted to an outboard wheel of the vehicle and an inboard tire mounted to an inboard wheel of the vehicle, the inboard wheel being mounted adjacent the outboard wheel at one end of an axle, and an aerodynamic fairing covering the outboard side of substantially all of the outboard wheel, the system comprising:
a fluid pressure source; and
a rotary union including a housing and a tee body removably coupled to the housing, the rotary union mounted to the fairing, the rotary union being in sealed fluid communication with the fluid pressure source;
a first air hose coupled between the tee body and the outboard tire so as to permit sealed fluid communication from the fluid pressure source to the outboard tire; and
a second air hose coupled between the tee body and the inboard tire so as to permit sealed fluid communication from the fluid pressure source to the inboard tire.
