Abstract: A system for estimating the remaining mileage on a tire that supports vehicle includes a processor in electronic communication with an electronic control system of the vehicle. A calibration module determines a wear rate of the tire, and the wear rate of the tire is communicated to the processor. A severity assessment module is in electronic communication with the processor, receives real-time inputs, and generates a real-time driving severity number. A mileage estimation module is in electronic communication with the processor and determines a current wear state of the tire. The mileage estimation module generates an estimate of remaining mileage on the tire from the wear rate of the tire, the real-time driving severity number, and the current wear state of the tire.
