Demand for high-performance automobiles is increasing due to the recent increase in imported cars and increased interest in car tuning. High-performance automobiles are equipped with large-width tires with low flatness and high stiffness of the sidewall to increase the treading force with the ground and to ensure posture stability when turning. Heat generation by friction between the tire and the ground and internal heat generation by repetitive bending of the sidewalls are the main causes of weakening the durability of tires. In particular, this durability weakness is maximized during circuit driving, and most high-performance vehicle and tire manufacturers are ensuring the durability of tires by running tests on the circuit prior to product launch. However, it is not easy to evaluate the durability of a tire in a circuit. Above all, high-speed of 200 km/h or more continues, so that much heat is generated in the vehicle corner module including the brake, and data measurement using a sensor such as a WFT(Wheel Force Transducer) is almost impossible. In this paper, the 6-axis load and the 3-axis angles acting on the tire at the circuit were calculated using the vehicle dynamics model. Based on this data, we developed the circuit simulation method by using drum type tire durability tester. The reliability of the developed endurance test mode was verified through comparison with actual vehicle test results.
