<p>The invention relates to a method of measuring wear in relation to at least one wheel-mounted (10) tyre casing (20) comprising tread design elements (27, 28). Moreover, the invention relates to a tyre casing (20), a wheel (10) and a mounted assembly (1) for carrying out said method as well as a motor vehicle comprising at least one such mounted assembly (1). The inventive wear measurement method consists in assigning a wear variable that is representative of the wear of the element(s) (27, 28) to an energy variable that is representative of the energy from electromagnetic radiation transmitted from outside each casing (20) to the internal space thereof by means of at least one of the aforementioned elements (27, 28). According to the invention, the bulk of the casing (20) comprises at least one electromagnetic radiation transmission means (50, 60) which is provided in order to transmit an incident ray from outside the casing (20) to the internal space thereof by means of at least one of the elements (27, 28), from the moment when the transmission means (50, 60) comes to the surface of the crown area (27a, 28a) of the element (27, 28).</p> |
