ABSTRACT:
An apparatus for mounting a wheel on a vehicle such as a trailer includes a hollow, non-rotatable axle, a wheel hub having a cavity therein and a valve or venting structure positioned between the axle and the wheel hub cavity. The wheel hub has an end connected to the hollow axle and its other end is sealed by an end cap. The cavity within the wheel hub has a volume of air which is substantially less than the volume of air within the axle. The valve is formed by a flexible membrane or diaphragm having a slit therein. The valve opens and closes in response to pressure differentials created between the wheel hub cavity and the axle by the membrane flexing to open or close the slit.
