VEHICLE TIRE MANAGEMENT SYSTEM INCLUDING WHEEL WITH SELF- CONTAINED TIRE INFLATION/DEFLATION APPARATUS ABSTRACT OF THE DISCLOSURE A high pressure air reservoir (26), a pump unit (28), (82,84) and an air pressure sensor (38) are provided on each wheel (18) of a motor vehicle. The sensor (38) senses the air pressure in a tire (22) which is mounted on the respective wheel (18). The pump unit (28), (82,84) is controllable to selectively pump air from the tire (22) into the reservoir (26) to deflate the tire (22), or to cause air to flow from the reservoir (26) into the tire (22) to inflate the tire (22). A control unit (12) which displays the sensed air pressure and controls the pump unit (28), (82,84) to inflate or deflate the tire (22) is mounted inside the vehicle for operation by the driver, and is electrically connected to the sensor (38) and pump unit (28), (82,84) by brush contacts (48,50,52,54,56,58) provided between the wheel (18) and axle (16) or inductive coils (100,104), (110,104) provided between the wheel (18) and an adjacent structural member (108) of the vehicle.
