do not forget me!Maintenance knowledge of car spare tire

Many car owners often neglect the maintenance of the spare tire and wait until a certaintireWhen an accident occurred, it was discovered when the spare tire was taken out that the spare tire was no longer usable.

1. Regular inspection of spare tires

During daily maintenance or before long-distance travel, few car owners test spare tires, and some unprofessional repair shops often neglect this.The spare tire inspection is mainly to check the tire pressure and whether there is abrasion and cracks. Before the tire pattern is worn to the wear mark line, it is necessary to check the tire as soon as possible.tireReplace it.

Reminder: If there are small cracks on the sidewall, you can't use it to run long distances or high-speed driving, because the tire sidewall is thin, and high-speed driving is prone to puncture.

2. Oil products and spare tires are not put together

The main component of tires is rubber, and rubber is most afraid of the erosion of various oils.The owner often stores it in the trunklubricating oilSuch as oil, once the oil gets on the tire, it will bulge and corrode the tire, which will greatly reduce the service life of the tire.

Reminder: If the tire gets oily, use a neutral detergent to wash off the oil in time.

3. Spare tire life is about 4 years

Many car owners believe that as long as the spare tire is kept in the trunk and not used, it can be "long-lived". This is wrong. It often happens that the car owner wants to replace the spare tire after a puncture, but finds that the spare tire has been severely aged after being left for many years, and it is already a waste tire. In fact, because tires are rubber products, they will age if they are stored for too long. Generally, the aging period of tires is about 4 years. Therefore, the spare tire should be replaced after 4 years.

4. The spare tire should not be used for a long time

Because the spare tire is used less frequently and has less friction with the ground, and the size of some spare tires is smaller than that of the normal tire, its flatness, tire width or tire diameter are different from those of normal tires, so replace it with a spare tire. After that, the friction coefficients of the four tires are different, the ground adhesion is different, and the air pressure is different. Long-term use will affect the vehicleBraking System,steering systemAnd the suspension system have a certain impact on the drivingseat beltThe hidden danger will also cause uneven friction of other tires in the same direction.

Reminder: Some spare tires use brighter colors, the purpose is to remind the owner to replace the spare tire in time. In addition, when using spare tires, especially miniaturized spare tires, pay attention to controlling the vehicle speed. Under normal circumstances, it is appropriate to not exceed 80 km/h.

5. Put the repaired tire on the rear wheel

Some car owners will use repaired tires as spare tires. If these tires are to be used again, they must be placed on non-driving wheels. Generally, the intermediate and lower vehicles we drive are front-wheel drive vehicles.carThe direction of the tire is more difficult to control, so the repaired tire should be placed on the rear wheel.
