Abstract

A tire pressure monitoring system comprising a sensor located inside a tire of a vehicle may be operable to measure one or both of a temperature inside the tire, and flexion of the tire. The tire pressure monitoring system may be operable to calculate an air pressure inside the tire based on one or both of the measured temperature and the measured flexion. Communications between the sensor and other components of the tire pressure monitoring system may be wireless, such as, for example, via an ISO 18000-7 link. The sensor may be embedded in the tire (e.g., in the sidewall, in the tread, or in the liner). The sensor may measures flexion of the tire at a point (e.g., the point where the tire meets the ground) where the tire is being compressed and at a point (e.g., the point opposite where the tire meets the ground) where the tire is not being compressed.
