Five precautions for the use and maintenance of automobile spare tires

Many car owners often neglect the maintenance of spare tires. When an unexpected situation occurs in a tire, the spare tire is only found out when the spare tire is removed.

1. Regularly test spare tires

In daily maintenance or before long-distance travel, few car owners test spare tires, and some unprofessional repair shops often neglect this. Spare tire testing is mainly to check the tire pressure and whether there is wear and cracks. Before the tire tread wears to the wear mark line, the tire should be replaced as soon as possible.

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

2. Oil products and spare tires are not put together

The main component of the tire is rubber, and the rubber is most afraid of the erosion of various oils. Owners often store oils such as lubricating oil in the trunk. Once these oils get into the tires, they will cause the tires to swell and erosion, which will greatly reduce the service life of the tires.

Reminder: If the tire is stained with oil, it should be washed away with a neutral detergent in time.

3. Spare tire life is about 4 years

Many car owners believe that as long as they keep the spare tire in the trunk and do not use it, they can "live for a long time." This is wrong. It is often the case that the owner wants to replace the spare tire after the tire burst, but finds that the spare tire has been seriously aging after being placed for many years, and is already a waste tire. In fact, because the tires are rubber products, the aging phenomenon will occur when 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

The spare tire has low frequency of use, less friction with the ground, and the size of some spare tires will be smaller than the size of the normal tire. Its flatness, tire width or tire diameter are different from the normal tires, so replace the spare tire After that, the friction coefficients of the four tires are different, the ground adhesion is different, and the air pressure is different. Prolonged use will have a certain impact on the vehicle's braking system, steering system and suspension system, which will bring hidden dangers to driving safety and will also make the same direction. The other tires have uneven friction and other phenomena.

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 speed of the vehicle. In general, it is better not to exceed 80 km/h.

5. Put the rear wheel after repairing the tire

Some car owners will use the 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-level vehicles we drive are front-drive vehicles, and because the front wheel is flat. The direction of the car is more difficult to control, so the repaired tires should be placed on the rear wheels.
