A tire wear state estimation system (10) is disclosed. The system (10) comprises: a vehicle (14); a tire (12) supporting the vehicle (14); a first sensor unit (26) being mounted on the tire (12), the first sensor unit including a footprint centerline length measurement sensor to measure a centerline length of a footprint of the tire; and a second sensor unit (96) being mounted on the tire (12), the second sensor unit including a shoulder length measurement sensor to measure a shoulder length of the footprint of the tire. At least one of the first sensor unit (26) and the second sensor unit (96) includes: a pressure sensor to measure a pressure (38) of the tire; a temperature sensor to measure a temperature (40) 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 first sensor unit (26) and the second sensor unit (96), the processor (36) being configured to receive the measured centerline length, the measured pressure, the measured temperature, the identification information, and the measured shoulder length; a tire construction database (44) storing tire construction data, the tire construction database (44) 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 preferably stored on the processor (36) and being configured to receive the measured centerline length, the measured pressure, the measured temperature, the identification information, the tire construction data, and the measured shoulder length as inputs. The analysis module (36) includes 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 (12) supporting a vehicle (14) is disclosed.
