Because the front wheel is the driving wheel, which is responsible for driving the car forward, and the front wheel is responsible for steering, the wear is larger than that of the rear wheel, but the rear wheel is easy to be pricked. In order to improve the driving stability of the car body, the rear wheel is usually tilted in the shape of a splay, so the daily wear of the rear wheel is not small. Therefore, it is usually recommended that you adjust the four wheels every 2, to 3, kilometers, and then rotate them to the front wheel and then to the rear wheel to make the tire wear more uniform.
