Abstract
A tire pressure monitoring apparatus (10) includes a pressure transducer (14) and a valve stem (12). A support bracket (50) connects the valve stem (12) to the pressure transducer (14) and facilitates pivotal movement between the valve stem and the pressure transducer. The support bracket (50) includes a valve stem biasing member (80) that exerts a spring bias on the valve stem (12) to help maintain a selected angular position of the valve stem relative to the pressure transducer (14).
