Tread wear appears as a consequence of friction, which mainly depends on surface characteristics, contact pressure, slip velocity, temperature and dissipative material properties of the treadmaterial itself. The subsequent description introduces a wear model as a function of the frictionalenergy rate. A post-processing as well as an adaptive re-meshing algorithm are implemented into afinite element code in order to predict wear loss in terms of mass. The geometry of block models isgenerated by image processing tools using photographs of the rubber samples in the laboratory. Inaddition, the worn block shape after the wear test is compared to simulation results.
