Do you know what a spare tire is? The full name of a spare tire is a spare tire, that is, a tire hung at the rear of the car or put in the trunk of a car, which you may never need. In most cases, it will be there silently, waiting for a one-thousandth chance. If something happens to Brother Lun, it will come in handy.

The spare tire is very important for car use, especially for high-speed travel. In order to avoid affecting the journey, we must pay attention to the replacement of spare tire. Some people may have encountered such a situation. During driving, one tire failed, and they tried to put on a spare tire, only to find that the spare tire they hadn't "cared about" for a long time was completely flat and could not be rescued at all. Usually, the spare tire is neglected for maintenance. Once there is a problem with the positive tire, it will be in big trouble. Therefore, as a car owner, it is necessary to have a general understanding of the spare tire, so as not to be at a loss if a spare tire is needed.

1. Do you know what kind of spare tire your car is?

At present, most cars will have a spare tire with the same size as the original tire. But some cars will use special color wheel spare tires, small spare tires, folding spare tires, zero-pressure continuous tires and so on.

1, full-size spare tire: Full-size spare tire is easy to understand, that is, spare tires with the same specifications as four original tires usually use the same rims as the original wheels; The size of the full-size spare tire is exactly the same as the other four tires of the original car, and it can replace any tire that is temporary or no longer available.

2. Non-full-size spare tire: Non-full-size spare tire is a spare tire with narrow tire width or small rim size, usually with iron rim, and the driving speed is limited (the maximum speed cannot exceed 80km/h), so it can only be used as a temporary substitute and can only be used for non-driving wheels.

3. Zero-pressure tire: Zero-pressure tire is also called run-flattire, which is also commonly known as "explosion-proof tire", which is literally translated as "run-flat tire" in the industry. Compared with ordinary tires, zero-pressure tires will not leak or leak at a very slow speed after being punctured, and can maintain the driving contour, and the beads can be fixed on the rim all the time, thus ensuring that the car can travel to the maintenance station stably for a long time or temporarily. Therefore, the car equipped with this kind of tire no longer needs to carry a spare tire, thus invisibly hiding the spare tire on four tires in another way.

Although the spare tire replacement vehicle instructions are available, I believe that 99% of people are eager to travel all over China after buying a car, and the instructions have long been forgotten. Ok, today I will tell you how to change the spare tire safely and quickly, and remember the main points in case of emergency.

Second, the use of spare tires and taboos:

Many car owners are very concerned about the four tires in use, and have a certain understanding of tire inspection and four-wheel rotation, but they often ignore the maintenance of the spare tire. Remind the majority of riders to pay attention to the daily inspection of spare tires. Don't wait for a tire accident. When the spare tire was taken out, it was found that the spare tire could not be used.

1. Check the spare tire regularly.

During routine maintenance or before long-distance travel, few car owners test the spare tire, which is often overlooked by some unprofessional repair shops. The inspection of the spare tire is mainly to check the tire pressure, wear and crack, and replace the tire as soon as possible before the tire tread is worn to the wear mark line. If there is a small crack in the sidewall, it cannot be used for long-distance or high-speed driving, because the sidewall of the tire is thin and it is easy to puncture at high speed.

2. The spare tire should not participate in tire adjustment.

In the specialty store, there are strict requirements for the replacement and use of the original tire, and the spare tire is not suitable for tire adjustment. Tire adjustment itself is to weigh the wear of different parts. Left and right tire adjustment is no longer advocated, and there are also problems of different wear before and after tire adjustment. Due to the different wear degree of spare tire, participating in tire adjustment will increase safety hazards.

3. Do not use the spare tire for a long time.

The spare tire is actually for emergency use, not long-term use. Whether the spare tire is wide or narrow, manufacturers have special production and use requirements. Because the spare tire is not hung on the car for a long time, it is not worn, so the worn tire is different from the worn tire, and there are certain safety hazards when the spare tire is used in the car.

During use, users can't change the original tire into a spare tire just because the car has run for several kilometers. Because the spare tire and the original tire have different production time, tire aging, hardening degree, service life and deformation degree, it is unsafe to use for a long time. The spare tire after emergency use should be replaced with the original tire in time.

4. The air pressure of the spare tire needs to be adjusted when it is used.

The spare tire pressure is different from the normal tire pressure. Before using the spare tire, adjust the spare tire pressure with a barometer. The tire pressure of ordinary low-pressure tires is between 2-2.2 "air pressure" and that of spare tires is between 2.7-3.2 "air pressure". The high-pressure spare tire cannot be used at high speed for a long time, because it can ensure the shape and reduce the probability of tire puncture when driving at high speed. After replacing the spare tire, the owner should find a professional to adjust the tire pressure in time and adjust it to a safe state (about 2.7 MPa).

5. Don't put the spare tires with corrosive substances together.

The main component of tire is rubber, and what rubber fears most is the erosion of various oil products. Car owners often store lubricating oil and other oil products in the trunk. Once these oils come into contact with tires, tires will swell and corrode, greatly reducing the service life of tires. If the tire is stained with oil, it should be washed off with neutral detergent in time.

6. If the spare tire is not used for a long time, it should be replaced in time.

Many car owners believe that the spare tire can "live long" as long as it is not used in the trunk, which is wrong. It often happens that the owner wants to replace the spare tire after a flat tire, only to find that the spare tire has been seriously aging and has been abandoned for many years. 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.

7. Repaired tires should be used on the rear wheels.

Some car owners will use repaired tires as spare tires. If you want to use these tires again, you must put them on non-driving wheels. Generally, the cars we drive at the intermediate level and below are front-driven, and because the direction of the car is more difficult to control after the front wheel has a flat tire, we should put the repaired tire on the rear wheel. In addition, when using spare tires, especially miniaturized spare tires, attention should be paid to controlling the speed, which generally does not exceed 80 km/h.

Third, how to replace the spare tire?

In the daily driving process, tires contact the ground for a long time, which is prone to natural wear, unnatural damage and man-made damage. How to deal with the tire damage during driving? Here's how to replace the spare tire independently, so as to deal with it in time in an emergency.

First, we need to find the location of the spare tire. According to different models, the spare tire is generally placed under the trunk floor; Hanging under the rear of the car; Fixed outside the trunk door.

1. Open the trunk and take out the spare tire and vehicle tools, including jack and wrench.

2. Loosen the bolt on the tire with a wrench. First, loosen counterclockwise and tighten clockwise. Loosen the tire bolts counterclockwise, because the bolts that fix the wheels are screwed tightly, so we can rely on our whole body strength;

3. Set the jack. After loosening the bolts one by one, you can use the jack to partially lift the vehicle. Attention should be paid when using the jack: there are many slots for placing the jack on both sides of the car bottom, so the jack must be placed in the slots to avoid accidents;

4. Remove the tire. After the jack is propped up, the loose bolts can be easily unscrewed in turn, and then the tire can be removed as a whole, which means that the tire disassembly work is successfully completed;

5. Install the spare tire. Before installing the spare tire, it is best to put the removed tire under the car to avoid the accident that the jack is misplaced and causes the car to land three times. The most difficult thing in the installation of spare tire is how to align the spare tire with the wheel fixing bolts. If the car rises too high, it will take a lot of effort to lift the spare tire. It's better to have someone else's help. If it is operated by one person, it is recommended to hold the spare tire with legs or feet to prevent it from shifting.

6. Tighten the tire bolts. Install the spare tire at the bolt or bolt hole, first screw on a bolt, then tighten it once, and finally tighten it slightly with a wrench; When screwing bolts, do not screw bolts clockwise or counterclockwise in turn, but diagonally. For example, there are five bolts to fix the tire. Let's tighten four bolts diagonally first, and then tighten the fifth bolt. When tightening bolts, it is best to keep the number of turns of each bolt consistent to ensure the uniform stress on the bolts.

7. Loosen the jack and remove it. After the five bolts are screwed on, we can remove the jack (and the tire under the car) and let the car return to the ground.

8. After that, tighten each bolt according to the physical strength when removing the tire, also diagonally. After tightening in turn, the replacement of the spare tire can be declared complete.

9. Put away the tools, put them back in the trunk and put the tires back.
