The main purpose of this paper was to determine the thermo-physical properties in different parts of tire rubber and analyze the influence of the thermo-physical properties with temperature variation on the curing temperature field of tire. Thermo-physical properties in different parts of tire rubber were measured by NanoflashTM in the curing process, the relation curve of thermo-physical properties on temperature was obtained, and the linear relations of heat conductivity and specific heat of rubber on temperature were obtained by the regression analysis. Using the finite element software to build a two-dimensional model of the tires, and curing temperature field distribution was predicted by simulating the tire vulcanization process .The temperature distribution and variation curve of temperature measuring points were obtained in the cueing process. The analysis result indicates that the thermo-physical properties have a significant impact on the temperature field, and the influence of the heat conductivity on temperature field is more obvious than that of specific heat.
