Practical ways to maintain cars.

Proper maintenance and use of cars will not only help to prolong the service life of cars, but also help to improve driving safety. Conventional automobile maintenance mainly includes the maintenance scope of engine system (engine), gearbox system, air conditioning system, cooling system, fuel system and power steering system. In addition to the above maintenance items, we should also pay attention to the daily maintenance of tires and conduct regular tire safety inspections.

The daily maintenance and safety inspection items of tires include the following points:

1. Air pressure check: the air pressure of the tire will naturally decrease with the increase of service time, and it will decrease 10-20kpa every month. Before driving, check regularly with the tires cooled, usually once a month. According to different models, the standard air pressure of vehicles will be different. Please adjust the air pressure according to the standard according to the door logo or fuel tank cover logo on the driver's seat side.

2. Wear inspection: improper air pressure or car condition problems may lead to abnormal wear; Common forms are single-sided grinding, middle grinding and double-sided grinding. In order to prevent potential safety hazards caused by abnormal wear during driving, please check the wear state of tires regularly. Observe that when the remaining groove depth is 1.6mm (if there are multiple grooves, take the lowest value), the tire wear mark has been reached. Please replace it with a new one in time. In addition, excessively worn tires (even if they don't reach the wear mark) are easy to slip, and their performance is degraded and dangerous, especially on wet roads. It is not recommended to continue using them.

The main measures to prevent abnormal wear include: ① periodic air pressure spot inspection; ② Carry out vehicle four-wheel alignment detection on a regular basis; ③ Replace the tires regularly.

3. Trauma examination: ① Check the tread. If it is punctured or deformed, it needs to be repaired or replaced in time; ② Check the tire sidewall. If the sidewall bulges or hurts the depth of the cord, please replace it in time. The tire sidewall cannot be repaired.
