A load estimation system for a tire is provided. The tire includes a pair of sidewalls extending to a circumferential tread and supports a vehicle. A sensor is mounted to the tire and measures an inflation pressure of the tire and a footprint length of the tread. A vehicle loading state estimator determines a loading state of the vehicle. An inflation correction factor is determined from the vehicle loading state. A pressure correction module receives the measured footprint length, the measured inflation pressure, and the inflation correction factor, and determines an adjusted footprint length. A de-noising module processor receives the adjusted footprint length to generate a filtered footprint length, and a wear correction module receives the filtered footprint length and corrects for wear of the tire to generate a wear-corrected footprint length. A load determination model receives the wear-corrected footprint length and determines an estimated load on the tire.

A tire sensor container system is provided. A tire includes a carcass toroidally extending from a first bead area to a second bead area, and an innerliner formed on an inner surface of the carcass. The tire sensor container system includes a tire pressure monitoring system sensor, which in turn includes a rigid housing that is formed with an oval shape. A flexible container is mounted to the innerliner. The container includes a base and a wall extending radially outwardly from the base, and the wall terminates in a lip. The container wall is formed with an oval shape that cooperates with the shape of the tire pressure monitoring sensor housing. A cavity is defined by the base, the wall, and the lip, and cavity receives and secures the tire pressure monitoring system sensor. The system reduces sensor rotation and maintains consistent sensor orientation to improve sensor functionality and longevity.
