1. A wear evaluation method for evaluating the wear of tire tread on a vehicle wheel tire, the method comprising the following measurement steps:
causing a transducer positioned on the vehicle in a proximity of the vehicle wheel tire to emit a first ultrasonic signal;
acquiring an electrical measurement signal produced by said transducer when it receives a second ultrasonic signal resulting from the first ultrasonic signal being reflected by a metal target incorporated in a thickness of a crown area of the vehicle wheel tire;
measuring at least one parameter of the electrical measurement signal; and
evaluating the wear of the tire tread on the vehicle wheel tire from said parameter.
