System and method for tracking tire tread wear

A system for tracking tread wear of a tire of a vehicle comprising:

• a processor configured to obtain a new tire rotational count value (Nn) representing expected rotations of the tire over a set distance if the tire were new;
• a position tracking device 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 coupled to the vehicle and configured to track rotations of the tire, wherein the processor is configured to:
• determine a current tire rotational count value (Nc) representing the number of rotations of the tire over the set distance based on data received from the position tracking device and the wheel speed sensor;
• and determine a tire tread wear value based on the new tire rotational count value and the current tire rotational count value;
• and
• a display device configured to display indicia based on the tire tread wear value.
