Automobile tire maintenance Qiu daren

Spare tires should be "scrapped" without expiration.

Now that we know that regular "rotation" can prolong the service life of tires, how and how often should we change the position of tires?

"Tire transposition is not changed casually, which is also a science." Liu, after-sales service director of Shanghai Volkswagen Liaoning Xinda Store, said that tire transposition should follow the tire adjustment suggestions of automobile manufacturers in the vehicle manual. If the manufacturer does not specify a specific tire adjustment cycle, the front-wheel drive car usually needs to be transposed every 8,000 kilometers, and the four-wheel drive car needs to be transposed every 6,000 kilometers. However, if there is no transposition over 20,000 kilometers and tire wear has formed, it is not recommended to transpose the tires to avoid deviation. Director Liu introduced the specific method of "changing posts" to the reporter. Generally speaking, front-wheel drive and rear-wheel drive vehicles are cross-transposed or directly switched. The adjustment method of single guide tire is different from this. The front and rear wheels can only be adjusted in a straight line, and cannot cross left and right.

In addition, Director Liu reminded the owner that if the specifications and structure of the spare tire are the same as the tires normally used by the car, the most scientific and reasonable method is to cross-transpose the spare tire and replace it together. After such a car runs 50 ~ 654.38+10,000 kilometers, the five tires (including the spare tire) are evenly worn and can be directly replaced together, and the spare tire will not be wasted, because the tires also have a shelf life, usually about 5 years after leaving the factory.

Do dynamic balance test after tire transposition.

What problems should be paid attention to when and after tire transposition? Wang Ziwei, after-sales maintenance manager of Kia Motors Liaoning Tonghe 4S shop, reminded the majority of car owners that they must pay attention to "four similarities" when changing tires, that is, tires with the same factory model, size, pattern and specification (number of carcass cords, allowable inflation pressure and load capacity). That is to say, if the vehicle only replaces the tires of individual factory models or patterns due to other factors such as flat tires, and some car owners use spare tires with slightly changed sizes, tire transposition cannot be simply carried out at this time, and tire transposition can only be carried out if the factory models, sizes, patterns and specifications are the same, otherwise it will also cause the phenomenon of deviation.

Manager Wang introduced that when changing tires, we should pay attention to making spare tires or installing them on non-driving wheels as much as possible, so as to ensure that the tires with the best condition are installed on the driving wheels, so as to avoid losing control of the direction due to puncture.

In addition, after the "rotation", it is best to do a dynamic balance and four-wheel positioning. Manager Wang introduced that the dynamic balance test should be carried out at the same time as the tire transposition. If the balance weights on both sides of the hub are uneven, the steering wheel will shake and the body will be unstable when the vehicle is driving. Therefore, tire transposition and dynamic balance are usually carried out at the same time. Moreover, the first tire rotation is very important. After each revolution, please don't forget to adjust the tire pressure according to the vehicle manufacturer's suggestion.
