The Study of the Influence of Temperature on the Tread Wear of All-Metal Cord Heavy-Loaded Radial Tire

In the present study, the wear resistance of the new tread rubber of the all-metal cord radial truck tire has been investigated at different temperatures: -25, +20 and +80 ° C at a constant normal pressure of 0.7 MPa and a sliding speed of 20 mm / s. The low sliding speed negates the increase in temperature, which appears at higher speeds. In order to assess the effect of temperature on the change in the wear mechanism, the surface of the tested rubber is investigated by the method of non-contact profiling. The paper shows how the wear rate and surface microrelief vary with the volume temperature of the tested rubber.
