Tire pressure check

Tire under pressure and over pressure will lead to abnormal wear of tires, shorten tire life, increase fuel consumption, and even increase the probability of tire blowout. It is recommended to check the tire pressure once a month to ensure the normal tire pressure.

The tyre pressure check must be carried out under the condition of the tyre being cooled. The tire pressure gauge or the tire pressure monitoring system (TPMS) can be used to check the tire pressure. The standard tire pressure will be specified in the vehicle specifications under various load conditions. At the same time, this parameter will be listed on the label of the driver's door.

Tire standard tire pressure is about 2.2~2.6bar, too high tire pressure easy to increase the wear of the tire, but also may cause a flat tire, and too low will increase fuel consumption and vehicle bumps. Generally speaking, the tire pressure in summer can be slightly lower, and it can be slightly higher in winter.

Always pay attention to wear marks of tires

The wear mark of the tyre is located in the main drain tank of the tyre, and it is a rubber boss with trapezoidal cross section. When the tread pattern is worn to the wear mark, the tire must be replaced. In rainy season, the tread depth must be kept above 3mm in order to prevent the vehicle from skidding in the seeper road.

Tires also have shelf life

Tires are rubber products, so rubber aging can happen. Tire rubber shelf life is generally 4-5 years. Tire rubber will accelerate aging after shelf life, resulting in lower tire performance.

Such as "9MCR0810" is the tire production date code. Among them, the last 4 "0810" said that the tire is "10" in the "8" week production products.

Attach importance to the four round transposition

If the vehicle appeared deviation, the direction of plate precipitation and tire wear problems in unilateral driving, these phenomena are in need to remind the owners immediately to vehicle four wheel alignment adjustment. The wheel wear speed is faster than that of the rear wheel because of the steering wheel. In order to prolong the service life of the tire, the tire transposition is carried out regularly, so that the tires can be uniformly worn. Auto repair experts suggest that the front wheel drive vehicle every 8000 kilometers to do a four wheel transposition.
