The mechanisms of heat generation and heat dissipation of tire are first discussed, and the heat generation capacity and the heat dissipation capacity per unit time are obtained through analysis of both tire contact pressure distribution and heat dissipation method. In this article, the method of theoretical analysis is used. According to heat balance condition of tire, the theory model of the steady-state surface temperature of tire is established based on tire temperature field tests. Finally, the effects of speed, load, and tire pressure on the steady-state surface temperature of tire are analysed. The results obtained are summarized as follows: (1) Speed, vertical load, and tire pressure have significant effects on tire temperature filed. With the increase of speed, the rate of tire deformation as well as the heat generation capacity increases, and thus results in higher tread temperature; with the increase of vertical load, the steady-state temperature of tread changes drastically; with the increase of tire pressure, the tire wear has been continuously decreasing because tire stiffness becomes greater, which results in that tire deformation, energy loss and heat generation decreases. (2) The established model of the steady-state surface temperature of rolling tire is feasible, and the results can reflect the wear conditions of tire, and therefore provides a theoretic foundation to predict the steady-state surface temperature for different types of tires under different driving conditions.
