A speed evaluation system is provided for assessing a speed of a vehicle. The speed evaluation system includes a wear measurement system, which assesses a state of a tire of the vehicle. The wear measurement system includes a casing placed on a ground surface. The speed evaluation system further includes a timing device that determines at least two instants of passage of the vehicle over two distinct or non-distinct points of passage of the casing of the wear measurement system, and a processor that calculates, as a function of the instants of passage and of dimensional data of the casing and/or dimensional data of the vehicle, a speed of passage of the vehicle over the casing. A method of implementing the speed evaluation system also is provided.
