Abstract
A computer-implemented method, an apparatus and a computer-program product for determining a quality of a tire. The apparatus includes a sensor array configured to obtain a footprint of the tire, and a processor. The processor determines an intensity profile of the footprint, locates an edge of a tread rib of the tire from the change in intensity, and determines from the location of the tread rib edge a relative quality of the tire.
