Abstract: A method for constructing a floating wheel cap using a modified original wheel cap. The original wheel cap is modified to provide a passage through the face of the original wheel cap and a positioning surface on the back of the original wheel cap. A fixed bearing retainer is fixedly attached to the back of the modified wheel cap using adhesive, and preferably using double sided tape. An offset weight floating cap is inserted through the passage in the modified wheel cap, through a bearing held in the fixed bearing retainer, and held in place by a ring. The offset weight floating cap is free to rotate in the modified wheel cap and includes an offset weight to urge the offset weight floating cap to a position displaying a design on the face of the offset weight floating cap in a desired position.

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.
