Remote tire pressure monitoring system with plastic thin-walled valve cap and method of installing the monitoring system
First Claim
1. A clamp-in tire valve comprising:
- a valve stem having first and second ends, a tire pressure monitor affixed to said first valve stem end;
a thin-walled plastic valve cap having an outer cap diameter, said valve cap removably coupled to said second valve stem end; and
a fastener having an inner fastener diameter, said fastener coupled to said valve stem adjacent said tire pressure monitor, wherein the outer cap diameter is smaller than the inner fastener diameter.

Abstract
A remote tire pressure monitoring system and method for installing the system are disclosed. The remote tire pressure monitoring system includes a pressure monitor, a tire valve assembly including a valve stem, a retention nut, and a plastic thin-walled valve cap which fits on an open end of the valve assembly. The outer diameter of the thin-walled valve cap is smaller than the inner diameter of the retention nut. As a result, the retention nut fits over the thin-walled valve cap. The tire pressure monitoring system is installed on a tire rim by threading the tire valve assembly with the valve cap in place through an opening in the tire rim and then passing the retention nut over the valve cap and tightening the retention nut onto the valve stem.
