1. A method for automatically determining mounting locations of tires mounted on a vehicle, comprising:
- providing each tire with a rotation sensor;
associating each tire with a unique identification;
associating a lateral acceleration sensor with the vehicle;
accumulating data from the rotation sensor during a measurement time frame defined by sensed lateral acceleration exceeding or falling below at least one lateral acceleration threshold;
associating the accumulated data with a tire'"'"'s unique identification; and
analyzing the accumulated data to determine the tire'"'"'s mounting location on the vehicle.

Abstract
Disclosed is an apparatus and methodology for identifying tire locations associated with a vehicle (10). Sensed variations in tire related parameters are measured as a vehicle traverses a known or ascertainable travel path (FIG. 3). Data accumulated over one or more measurement windows may be analyzed to determine the location of each individual tire (20) associated with a vehicle (10). Measurements and accumulation of data may be initiated upon detection of a stationary vehicle state exceeding a predetermined time, a predetermined lateral acceleration, and/or a predetermined vehicle speed.
