A system for tracking tread wear of a tire of a vehicle includes a processor configured to obtain a new tire rotational count value representing expected rotations of the tire over a set distance if the tire were new. A position tracking device is coupled to the vehicle and configured to track a distance traveled by the vehicle and report the distance to the processor. A wheel speed sensor is coupled to the vehicle and configured to track rotations of the tire. The processor determines a current tire rotational count value representing the number of rotations of the tire over the set distance. The processor then determines a tire tread wear value based on the new tire rotational count value and the current tire rotational count value. A display device is configured to display indicia based on the tire tread wear value.
