Specification use / regular maintenance spare tire use common sense introduction

Today, most cars are equipped with a spare tire that can be temporarily replaced. Some of them have the same dimensions as the original car (full-size spare tires), and some use special colors to remind owners to check or replace faulty tires in time. Wheel hubs, as well as non-full-size spare tires, folded spare tires, and zero-pressure tires. So, what should we pay attention to when using spare tires? Next, we will give you a detailed introduction.

First of all, let's find out what it means to have spare tires of different names:

1. Full-size spare tire: The size of the full-size spare tire is exactly the same as that of the other four tires in the original vehicle, and it can replace any tire that is temporarily or can not be used.

2. Non-full-size spare tires: The tire diameter and width of this spare tire are slightly smaller than those of the other four tires, so they can only be used as temporary replacements, and they can only be used for non-drive wheels, and the maximum speed cannot exceed 80km/h.

3, zero pressure tires: zero pressure tires are also known as safety tires (run-flat tire), which is what we commonly known as "explosion-proof tires", the industry's direct translation as "run-flat tires." Compared with ordinary tires, zero-pressure tires do not leak or leak very slowly after they have been punctured. They can maintain the running profile and the bead can always be fixed on the rim, thus ensuring that the car can be stable for a long time or temporarily. Go to the repair station. Therefore, a car equipped with such a tire no longer needs to carry a spare tire, so that the spare tire is hidden invisible on the four tires in another way.

Next, let's take a look at those places where we have to pay attention to everyday use of spare tires:

First of all, because of the low frequency of use of the spare tire, the degree of wear of the spare tire is different from that of the other four tires. Therefore, the friction coefficient will also be different. If the spare tire is used for a long time, it will have a brake system, steering system and Suspension system has a certain impact, but at the same time it will bring certain hidden dangers to traffic safety. Therefore, we should promptly remediate the damaged tires and replace them with spare tires. In addition, pay attention to adjust the air pressure when changing the spare tire, because the spare tire air pressure and the tire in use there is a certain number of differences, so before the replacement of the use of barometer to adjust it to normal after normal use.

Many consumers are very concerned about the four tires in use, including certain knowledge about routine inspections, four-wheel transposition, and other related knowledge, but they have neglected the maintenance of spare tires. In fact, spare tires that can help you in the emergency will also require us to double our care. We must not accidentally take out a spare tire and only discover that it is no longer in use.

1, regular inspection of the spare tire: In daily maintenance or long-distance travel, the spare tire should be tested for wear or cracks, if worn to the mark line, then it should be replaced as soon as possible. If there is a small crack on the sidewall, it cannot be used to run long distances or high speeds, because the thin tire sidewalls are prone to puncture when running at high speed.

2, do not put together with corrosive items: Because the main component of the tire is rubber, and rubber is most afraid of all kinds of oil erosion. Some owners often store similar oils such as lubricating oil in the trunk. When these oils touch the tires, the tires will distort to a certain degree, which will greatly reduce the service life of the tires.

3, the spare tire also has a life: Do not think that the spare tire has not been used in the trunk, you can "longevity." Some car owners may have encountered this kind of situation. When the tires are tied or damaged and they want to replace them with spare tires, they find that the spare tire has been severely deteriorated and cannot be used. This is because the tires are rubber products. If they are stored for a long time, they will be aging. The general aging period is about 4 years.

4. The spare tire should not be used for a long time: Because the spare tire is used at a low frequency and the friction coefficient with the other four tires is different, and the flat ratio, tire width or tire diameter of the non-full-sized spare tire is different from that of normal-use tires, therefore Prolonged use will have a certain impact on the vehicle's braking system, steering system and suspension system, causing hidden dangers to vehicle safety, and also causing uneven friction in other tires in the same direction.

5. After the repair, it should be placed in the rear wheel: if the repaired tyre is to be used again, no matter what kind of driving method the vehicle should be placed on the rear wheel, because the risk coefficient after the front tyre burst is relatively higher. , so the repaired tires will be relatively safe in the rear wheels.

Although spare tires are not always used, they can help you in the event of a malfunction or some emergency. The seldom used does not mean that we can always ignore it. If you are too indifferent to it, you will probably get more disappointment when you need it. Therefore, using and maintaining spare tires in a regular manner is an essential task and responsibility for each owner.
