A tire wear state estimation system (10) is disclosed. The system comprises a vehicle (14); a tire (12) supporting the vehicle; and a sensor unit (26) being mounted on the tire, the sensor unit including: a footprint centerline length measurement sensor to measure a centerline length of a footprint of the tire; a pressure sensor to measure a pressure of the tire; a temperature sensor to measure a temperature of the tire; and electronic memory capacity for storing identification information for the tire. The system further comprises a processor (36) in electronic communication with the sensor unit (26), the processor being configured for receiving the measured centerline length, the measured pressure, the measured temperature and the identification information; a tire construction database storing tire construction data, the tire construction database being in electronic communication with the processor (36), wherein the identification information is correlated to the tire construction data; and an analysis module (52) being stored on the processor (36) and configured for receiving the measured centerline length, the measured pressure, the measured temperature, the identification information, and the tire construction data as inputs, the analysis module (52) including a prediction model (76) to generate an estimated wear state for the tire (12) from the inputs. Also, a method for estimating the wear state of a tire supporting a vehicle is disclosed.
