1. An auto-location system, the system locating a position of a tire supporting a vehicle, the system comprising:
a first tire sensor unit being mounted on a first tire, the first tire sensor unit including a first footprint length measurement sensor to measure a length of a footprint of the first tire, and electronic memory capacity to store an identification of the first tire sensor unit;
a second tire sensor unit being mounted on a second tire, the second tire sensor unit including a second footprint length measurement sensor to measure a length of a footprint of the second tire, and electronic memory capacity to store an identification of the second tire sensor unit;
a processor in electronic communication with the first and second tire sensor units;
a vehicle status determination module in electric communication with the processor, the vehicle status determination module receiving the measured footprint length of the first tire and the measured footprint length of the second tire, and determining when the vehicle is in at least one of a static state and a cruising state;
a mean calculation module in electric communication with the processor, the mean calculation module receiving the measured footprint length of the first tire and the measured footprint length of the second tire from the vehicle status determination module when the vehicle is in at least one of a static state and a cruising state, and determining a first mean footprint length corresponding to the first tire sensor unit and a second mean footprint length corresponding to the second tire sensor unit;
a comparison module in electric communication with the processor, the comparison module receiving the first mean footprint length and the second mean footprint length, and determining a longest and a shortest of the first mean footprint length and the second mean footprint length; and
a position determination module in electric communication with the processor, the position determination module generating a position determination of the first tire sensor unit and the second tire sensor unit based on the longest and the shortest of the first mean footprint length and the second mean footprint length.
