1. An irregular wear detection system for a tire supporting a vehicle, the system comprising:
a sensor unit being mounted on the tire, the sensor unit including a footprint centerline length measurement sensor to measure a centerline length of a footprint of the tire;
a processor in electronic communication with the sensor unit, the processor receiving a plurality of measured centerline lengths of the footprint of the tire over time;
an analysis module being stored on the processor, the analysis module receiving the measured centerline lengths as inputs and comparing the measured centerline lengths over time, wherein the analysis module detects irregular wear of the tire based upon the measured centerline lengths remaining the same or increasing; and
an irregular wear determination being generated by the analysis module when the measured centerline lengths remain the same or increase.
