The transient temperature profile of a slipping tire is calculated by taking into account the frictional heating due to slip, temperature build-up due to hysteresis, convection and radiation loss into the air, and conduction cooling into the ground. Specific attention is directed to the calculation of tire surface temperature. Calculated surface temperature shows a value which may exceed the melting point of tread rubber. The phase change of the trad rubber at the surface leads to a particular wear mechanism. Wear of the tire is calculated for the transient process which occurs at the contact area between tire and ground.
