Rim mounted pressure monitoring system for a tire
First Claim
1. A tire and wheel rim assembly comprising:
- a tire supporting rim having an outward facing mounting surface;
at least one tire body mounted to the rim positioning an internal tire cavity over the rim mounting surface;
at least one tire pressure monitoring module assembly affixed to the rim mounting surface within the tire body internal tire cavity, the module assembly comprising;
a housing mounted to the rim mounting surface, the housing having an internal pressure chamber;
a pressure sensing device within the housing pressure chamber; and
a portal communicating with the internal housing pressure chamber and selective alternative regions along the rim mounting surface, wherein the air pressure at the selective alternative regions is communicated through the portal to the internal housing pressure chamber.

Abstract
A tire and wheel rim assembly includes a tire supporting rim having an outward facing mounting surface and at least one tire body mounted to the rim and positioning an internal tire cavity over the rim mounting surface. A tire pressure monitoring module assembly mounts to the rim mounting surface and includes a housing having an internal pressure chamber; a pressure sensing device and/or a temperature measuring sensor within the housing pressure chamber; and an elongate connecting member extending through the housing and the rim mounting surface. A crossover pipe connects the housing pressure chamber with a remote portion of the rim. The inflation pressure in the tire cavity is transferred through the axial passageway of the crossover pipe to the pressure chamber within the module housing.
