An air maintenance tire system and method in accordance with the present invention includes an air pumping mechanism configured to maintain air pressure within a first tire and a second tire in a dual tire arrangement. The system includes a control valve assembly attached to an elongate valve stem projecting from a rim of a first tandem tire, and a one-way valve carrying connecting tube from a sidewall air pumping passageway within a sidewall of the first tire. The control valve assembly further includes first and second outlet tubes connected to the elongate valve stem to selectively pass pressurized air into the tire cavities of both tandem mounted tires on an as-needed basis.

An inflation manifold connected to dual pneumatic tires by air hoses provides a central location for tire inflation and location of pressure sensors. A hose block connected to dual pneumatic tires by air hoses provides a central location for location of pressure sensors. The pressure sensors may be TPMS sensors or a combination of TPMS sensor and pressure gauge.

A method for locating the wheels of a vehicle equipped with an electronic module, according to which the transmission, by transmitting antennas mounted on the vehicle, of a predetermined number of identification request signals is commanded, and the values representative of the rates of reception of these signals by the electronic modules are analyzed. According to the method, centroid calculations are performed to determine, for each wheel position, the ideal position {right arrow over (LA.sub.j)} for reception of the transmitting antennas covering the wheel position (a reception rate of 100%), and, for each electronic module, the actual position of the latter {right arrow over (WU.sub.i)} relative to the position {right arrow over (TA.sub.i)} of the transmitting antennas fitted to the vehicle, using as the criterion for determining this actual position {right arrow over (WU.sub.i)} the rate of reception, by the electronic module, of the signals transmitted by each transmitting antenna.

Valves and related systems are described for equalization of pressure between vehicle tires. Valves may, for example, comprise a valve body which selectively opens when a vehicle is in motion so as to selectively allow two-way communication between vehicle tires.

An aerodynamic system comprising a torsion tube, a first rotatory coupling coupled to the torsion tube and adapted to mount to a first wheel hub, a second rotary coupling coupled to the torsion tube distal from the first rotary coupling and adapted to mount to a second wheel hub, and a non-rotating fairing panel mounted to the torsion tube.

A tire inflation assembly includes a housing that includes a fluid supply port and at least partially defining a fluid chamber in fluid communication with the fluid supply port. The tire inflation assembly further includes a first valve subassembly operatively connected to the housing and in fluid communication with the fluid chamber, wherein the first valve subassembly is configured to be operatively connected to and in fluid communication with a first tire. The first valve subassembly includes a first fluid valve and a second fluid valve each disposed between and in fluid communication with the fluid chamber and with the first tire. The first fluid valve is configured to open responsive to a pressure differential between the fluid chamber and the first tire, and the second fluid valve is configured to open responsive to pressure in the fluid chamber being greater than a first pressure threshold.

Rotor with breather and anti-rotation arrangement for tire calibration arrangements that provides a suitable breather of the axle hub, and, in turn, an improved oil retention thus preventing the premature wear of internal pieces and possible accidents during its operation.
