Abstract: The steady-state temperature distribution in the rolling tire was measured under different working conditions. In order to determine the real situation of the tire in drum test, which is essential in the following numerical simulation, a method that combines angular velocity measurement and numerical simulation is presented. The steady-state temperature distribution in the rolling tire is predicted with finite element method according to the uncoupling idea. The calculated temperatures at several internal points in the tire are compared with the measured ones. The agreement of them indicates the reliability of the method. The influences of load and initial inflation pressure on steady-state temperature distribution were discussed with this method. Numerical results show that the temperature of the whole tire rises with the load increasing, while the temperature of the tire side decreases with the initial inflation pressure increasing. In addition, the temperature distribution at tire tread is only slightly affected by different initial inflation pressures.
