Claim 19:
20. A method for determining a tire tread wear estimation of a tire, comprising:
receiving, by a controller, a direct tire tread wear measurement;
performing, by the controller, an indirect tire tread wear estimation, wherein the indirect tire tread wear estimation is based on sensor data received from one or more vehicle sensors, and vehicle dynamic data received from one or more vehicle systems;
performing, by the controller, a data fusion of the indirect tire tread wear estimation with the direct tire tread wear measurement;
estimating, by the controller, a percentage tire life remaining and a mileage to end of tire life based on the data fusion performed by the controller; and
estimating, by the controller, a refined tire tread wear calibration coefficient for performing future indirect tire tread wear estimations.
