In order to further clarify the temperature rise characteristic of engineering vehicle refurbished tire, computer geometry models and the finite element analysis modals of the 26.5 R25 engineering vehicle refurbishment tire were built using Pro/E Wildfire and ANSYS Workbench software, the boundary conditions of finite element analysis of steady state temperature field was determined, then the steady-state temperature field test system for the rolling working condition of engineering vehicle refurbished tire was constructed, and last the temperature field distribution characteristics and heat flux distribution characteristics of the tire layer, buffer layer, belt layer, tread body layer, tire side layer and toe mouth rubber layer along the width direction and radial direction of the tire were obtained. The simulation and test results are shown: the two sides of the tread body layer shoulder had the highest temperature, with the lowest temperature on the belt layer, buffer layer, and both sides along the width direction of tread body layer. The interior temperature of the refurbished tire increased with the speed of the running tire, among them, the temperature of the buffer layer and the tire layer increased greatly, and the tread body layer was the second, and the temperature of the belt layer was the smallest. The maximum heat flux was near the shoulder position of the tread body layer.
