Why are the outer tires behind the car worn?
Within 20000 kilometers, the front wheels are interchanged (about to the opposite) every 5000 kilometers. The rear wheels are the same. 20000 km, front and rear wheel down, and every 5000 kilometers of front wheel swap, the same rear wheel. In this way, each tire runs 20000 kilometers in front and back, during the period of reciprocal pouring. The normal life of tires is about 6~8 kilometers, generally speaking, the driving wheel wear will be more. Under normal circumstances, every twenty thousand kilometers of tire transposition, choose the same side before and after transposition or transposition transposition is more commonly used, in order to achieve the purpose of uniform use of tires.
Changing tires regularly allows for uniform wear, longer tire life, and better operating performance throughout the tire life cycle.
There are many reasons for wear on the side of the tire: the vehicle is running off, the load is on one side, the regular route is fixed, driving habit and so on, which will cause wear on the side of the vehicle. This is also difficult to avoid, so one of the regular maintenance of the vehicle is a tire exchange.
