The invention discloses a device (1) for measuring tyre wear comprising an ultrasound emitter (2) and an ultrasound receiver (3) such that, by means of the emission by the emitter (2) of an ultrasound wave through a material of the tyre (10) and the reception by the receiver (3) of said wave after bouncing against the rolling surface (SR), a distance between the inner face (10i) and the rolling surface (SR) of the outer face (10e) is obtained. The frequency of the ultrasound wave is between 100 kHz and 500 kHz. The invention further discloses a tyre comprising said device (1), as well as a method for measuring tyre wear using said device (1). L'invention concerne un dispositif (1) de mesure d'usure de pneu comprenant un émetteur d'ultrasons (2) et un récepteur d'ultrasons (3) de telle sorte que, grâce à l'émission, par l'émetteur (2), d'une onde ultrasonore à travers un matériau du pneu (10) et à la réception, par le récepteur (3), de ladite onde après rebond contre la surface de roulement (SR), une distance entre la face interne (10i) et la surface de roulement (SR) de la face externe (10e) est obtenue. La fréquence de l'onde ultrasonore est comprise entre 100 kHz et 500 kHz. L'invention concerne en outre un pneu comprenant ledit dispositif (1), ainsi qu'un procédé de mesure d'usure de pneu à l'aide dudit dispositif (1).
