Abstract: A newly developed tire rubber friction test machine is introduced. Friction test method of tire rubber is provided. Test data of tire rubber friction on concrete and icy road surface is obtained and analyzed. Effect of different road surface, ambient temperature, contact pressure and slip velocity on friction coefficient is apprehended. The dynamic friction is introduced to tire semi-empirical modeling and the accuracy of the model is improved. A way of forecast tire property on high rolling speed from low rolling speed tire test is illustrated.
