ABSTRACT:
The problem of a visible, rim-mounted valve stem for inflating a customized wheel-mounted tire is obviated by a wheel configuration that translates the tire inflation location from a valve stem mounted on the wheel rim to a hub location where a readily accessible tire inflation port can be effectively hidden beneath a locking center cap, making the access port tamperproof. A tire inflation passageway is integral with a spoke that connects the wheel hub to the wheel rim. In a preferred embodiment the wheel is a unitary cast structure, with the tire inflation passageway integrally cast as part of one of the spokes. The hub portion of the wheel has an inflation access port in fluid communication with the tire inflation fluid passageway, thereby providing for the application of pressurized air to the fluid passageway, so that inflation air flowing therethrough may be supplied to the interior of a tire mounted on the wheel rim and thereby control the tire pressure of the tire.
