A finite element model of temperature field of road wheel's rubber flange was established. The method of calculating heat generation ratio of the model's node and heat transfer coefficient of surface was put forward. The temperature field of a kind of road wheel's rubber flange was calculated with finite element analysis software ANSYS, and the effect of five parameters on the highest temperature of wheel flange was analyzed. Through analysis of the calculated results, it was shown that the model established is feasible in analyzing the temperature field of solid tire. Reducing the loss factor of wheel flange's rubber, increasing the heat transfer coefficient of rubber and reducing the thickness of rubber flange would benefit reducing the heat generation of road wheel.
