Abstract:
1. A vehicle wheel service system having a rotating spindle shaft for receiving a vehicle wheel assembly consisting of a wheel rim and tire mounted there on; the vehicle wheel service system further having a drive motor for rotationally driving the rotating shaft under control of a processing system and a controlled load roller for applying a generally radial load to an outer circumferential surface of the vehicle wheel assembly during rotation, comprising: wherein the processing system is further configured with a set of software instruction to obtain a measure of tire deformation acoustical energy, said tire deformation acoustical energy generated by the wheel assembly during rotational movement while said tire is continuously deformed under an applied radial load from the controlled load roller; and wherein the processing system is further configured with a set of software instructions to process said obtained measure of tire deformation acoustical energy to identify tire characteristics consisting of a relative tire loudness level, a measure of road noise, a surface non-uniformity, a representation of tire tread wear, and an inflation condition.
