Abstract: Electric vehicles have continued to grow rapidly in recent years, with a stable market share of over 30%. Various tire companies have also launched specialized tires for electric vehicles. Electric vehicles have significant differences compared to traditional fuel vehicles: the increase in vehicle weight, changes in power forms and energy replenishment methods, and these differences bring many challenges to the tire development of electric vehicles. In response to their differences, this article analyzes the complex requirements for the performance of electric vehicle tires: low rolling resistance, low noise, high load capacity, high tire pressure, good wear resistance, good wet and dry grip performance, lightweight, and briefly describes the development and testing process of electric vehicle tires. To improve the accuracy of performance definition, the fuzzy analytic hierarchy process (FAHP) is proposed to determine the priority of various performance parameters of tires, and the tire test results are comprehensively evaluated and selected using FAHP. Finally, the key performance achievement methods of electric vehicle tires are analyzed and discussed.
