Abstract
A vehicle tire monitoring system provides enhanced information about the contact patch interface area between the tire and the underlying road surface. The system has first, second, and third sensors (20A, 20B, and 20C) located on a tire (12) and sensing first, second, and third tread contact lengths (LA, LB, and LC) during which the tire (12) contacts the ground surface (18). The system also includes a controller (42) for processing the first, second, and third tread contact lengths (LA; LB, and LC) to determine a characteristic of the monitored tire (12).
