Patent number: 7119896Abstract: The tread wear on a tire is measured while the tire is mounted on a wheel. Electromagnetic energy is transmitted to an internal space of the tire via a transmission element disposed in a tire tread element. That transmitted energy is detected inside the tire, and an energy variable from the detected electromagnetic radiation is determined which is used to determine a wear variable representative of wear on the tire tread element. A signal transmitter disposed within the internal space sends signals representative of the wear.Type: GrantFiled: July 20, 2004Date of Patent: October 10, 2006Assignee: Michelin Recherche et Technique S.A.Inventors: Gilles Godeau, Michel Robert, Georges Peyron, Gilbert Menard
