Abstract: A reliable, low cost mounting assembly for a tire pressure transducer removably mounts the transducer on a multi-piece automobile wheel to enable the transducer to transmit tire pressure information that will enable the detection of an unsafe tire pressure. The mounting assembly includes a mounting bracket, a valve stem that passes through an air hole in the wheel and secures the mounting racket to the wheel while facilitating the adjustment of tire pressure, and a set of seals that seal both the valve stem and the mounting bracket relative to the air hole in the wheel. The mounting bracket has a generally flat base and a tab that extends radially outward from the base on one side at an oblique angle that assures proper positioning of the transducer within the wheel drop.
