As one of the important components of the automobile driving system, the automobile tire will not only bear the weight of the whole vehicle, but also have a crucial impact on the performance of the automobile, such as power performance, economy performance, passing ability, ride comfort, handling stability and braking performance. In the actual application process, the tires of all kinds of cars are worn to varying degrees, and the designed service life of tires is generally not less than 50000 km. However, many domestic self-owned brand cars fail to meet this requirement. The wear of tires will directly affect the service life of tires. It is of great significance to analyze the causes of tire wear correctly and ensure the correct use of tires to extend the service life of tires and improve the service performance of automobiles. This paper analyzes the causes of tire wear through the study of K&C characteristics of suspension, and puts forward improvement measures.
