ABSTRACT An apparatus and technique for determining the abrasion potential for tire treads is presented. A tire is rotatably and forcefully brought into contacting engagement with a reflective surface received upon an illuminated glass plate. A charge coupled device monitors the internal reflection light which evidences agrey level corresponding to the force of engagement between the associated portion of the tire and the glass support plate. A marker is placed upon the tire centrally within a region of interest. The video image of the marker and region of interest is analyzed as to slip and force at that area. The product of the slip and force functions is an indication of frictional work at the interface between the tire and support surface and is correspondingly an indication of the propensity of the tire to wear.
