Abstract
A high pressure air reservoir, a pump unit and an air pressure sensor are provided on each wheel of a motor vehicle. The sensor senses the air pressure in a tire which is mounted on the respective wheel. The pump unit is controllable to selectively pump air from the tire into the reservoir to deflate the tire, or to cause air to flow from the reservoir into the tire to inflate the tire. A control unit which displays the sensed air pressure and controls the pump unit to inflate or deflate the tire is mounted inside the vehicle for operation by the driver, and is electrically connected to the sensor and pump unit by brush contacts provided between the wheel and axle or inductive coils provided between the wheel and an adjacent structural member of the vehicle.
