How to maintain tires

In fact, the contact area between the tire and the road is only the size of a person's palm, but your safety, comfort and fuel economy all depend on this very small tread, so how to maintain the tire has become a top priority. In daily life, we can refer to the following points:

① Four wheel alignment

Correct four-wheel alignment helps to ensure the normal operation of your vehicle and improve the performance of tires. Poor wheel alignment will also lead to irregular tread wear and shorten the service life of tires.

② Tire alignment

In order to obtain uniform tire wear and prolong the service life of the tire, tire alignment is necessary. The standard of tire alignment is generally subject to the guidance on tire alignment in the vehicle manufacturer's user manual. For vehicles equipped with new symmetrical pattern or asymmetric pattern tires of the same specification (whether front drive, rear drive or 4WD vehicles), each tire alignment is generally carried out every 8000-10000 km, but if uneven wear is found on the tread (common on the driven wheel), It is necessary to carry out the cross transposition of the front and rear wheels as soon as possible and in time. If the specifications of the front and rear axles of the original tires of the vehicle are different, it is not allowed to adjust the position between the front and rear axles.

③ Tire repair

The tire must be removed from the rim and checked by a professional tire dealer before deciding whether it can be repaired. It is clearly stipulated that the sidewall cannot be repaired, the hole diameter penetrated by the crown cannot be repaired when it exceeds 6mm, and it cannot be repaired when there are abnormal conditions such as damage or deformation of bead, deformation of tread, corrosion of rubber by chemicals or rolling damage of tire due to lack of air.

④ When the tire pressure does not meet the standard, the driving risk is high

When the vehicle is running, the correct air pressure meeting the requirements shall be maintained. This air pressure shall refer to the information provided by the vehicle manufacturer. The owner should check the air pressure of all tires under cooling conditions at least once a month, even including the spare tire. If the air pressure decreases too fast, find out the cause immediately. Be sure to check the air pressure before a long journey.

⑤ When the vehicle shakes, be aware of whether it is a tire problem

When the owner feels that the vehicle vibrates excessively, he should be alert to whether there is a problem with the tire, or the tire positioning is poor, or the tire wear consumption is uneven, such as the tire shoulder wear is faster than the rest of the tread, etc.

When these conditions occur in the tire, continued driving will not only damage the tire life, but also affect the vehicle handling and cause danger.
