Abstract: The tyre includes a tyre tread configured so that, beyond a predetermined radial wear threshold, the tyre tread has a set of at least one wear indicator, including a so-called “sound” cavity arranged in a circumferential groove of the tyre tread. During the monitoring method, an acoustic signal that is able to include an acoustic footprint noise produced by the set during the running of the tyre on a ground beyond the predetermined threshold is detected by an acoustic sensor mounted on the vehicle, and information relating to the acoustic signal is emitted to a remote server not mounted on the motor vehicle.
