The influence of initial curing temperature on curing temperature field and cure state in the process of tire curing was studied by FE (Finite Element) analysis method. Preheating was carried out under atmospheric pressure. Preheating temperature should be lower than curing temperature to prevent the air bubbles. The temperature was set at 20°C, 30°C, 40°C, 50°C, 60°C, 70°C. The results show that the preheating treatment cause the temperature rise uniformly in each parts of the tire, which not only shortened the curing time in the curing press, but also improved the uniformity of curing state of the tire.
