US Patent 12070971 Device and method for automatically determining wear of tires

A method of determining a wear of a tire, which may include, using a computing device operating a processor: based on signals from one or more sensors of a vehicle, determining a plurality of tire parameters of a tire; based on at least a portion of the tire parameters, determining a normalized rolling radius of the tire, the normalized rolling radius being an effective rolling radius of the tire under a zero rotational speed, a zero load or both; and based on a change in the normalized rolling radius of the tire over a period of time, determining an average wear value of the tire.
