Can a car spare tire be used as a main tire?

Yes, but it depends on whether the quality of the spare tire and the main tire are the same.

A spare tire is a temporary tire for use in an emergency. In order to ensure the correct and safe tire rotation, only tires of the same structure and specifications can be used. The specifications and structure of small spare tires are different from those of normal tires in the car.

1. The spare tire is not worn, which is different from the commonly used tire, and the spare tire is used as an emergency tire and should not be used for a long time. The spare tire is hung on the car for a long time and is not subject to wear and tear, so it is not the same as the usual tire. In addition, the spare tire is also unsafe if it is not hoisted properly.

There are strict requirements for lifting tires in specialty stores.

2. The air pressure of the spare tire is different from that of the commonly used tire, and in order to ensure the shape and use of the spare tire during the storage process, the air pressure selection is different from that of the commonly used tire. Generally, low-pressure tires are between 2 0 and 2 5, while spare tires are between 2 5 and 3 0. The air pressure of the spare tire is unqualified, because the owner does not have an air pressure gauge, there is no way to adjust the air pressure Therefore, after changing the spare tire, you should find a professional to adjust the air pressure in order to use it normally.

Generally, it is safe to hit the spare tire pressure to 2 7.

3. Spare tires cannot be used as common tires. After the car ran for 100,000 kilometers, some car owners used the spare tire as a common tire, and the original tire as a spare tire, which is also not good. Because the production time is not the same, the degree of tire aging is also different, so it is very unsafe.

It depends on your model, some cars come with a full-size spare tire, and some cars are small-sized for emergencies. My own is a Chrysler imported car, the built-in is not a full-size spare tire, can be emergency, but you need to go to 4s as soon as possible to replace the original wheels, not suitable for a long time (it is said that Chrysler's full range of models are not full-size), that is to say, it is not suitable to use a spare tire for a long time, but some cars are full-size spare tires, as long as it is a full-size spare tire, it can be used as a normal tire. You just look at the size of the tires, it's obvious.

Generally, when buying a car, the spare tire he delivered is the original tire, which is the same as the other four wheels, and can be used for daily driving.

It is easy to change because of the car, if your car is a full-size spare tire, you can use it, if it is a small tire, then there is a problem because of what you said"Lord"It should be the driving wheel, because the driving wheel is driven, so it is not allowed to go up the small tire.

Spare tires should not be used as normal tires. According to the size, spare tires are divided into non-full-size spare tires and full-size spare tires, so let's talk about them separately.

1. The biggest difference between the non-full-size bending and the normal tire is that the tire specification and size are smaller than the normal tire! If the special spare tire is used as a normal tire for a long time, the finger will cause the vehicle to act on one side due to unbalanced pressure, so it is more prone to puncture, and if it is high-speed driving, it is more dangerous!

2. Although the specifications and dimensions of the full-size spare tire are exactly the same as those of normal tires, the spare tire cannot be used as a normal wheel buried spare tire for a long time. Because the four tires of the car are normal with the use time of the car, almost all are the same degree of wear and tear, and will not affect the stability of the vehicle in driving.

In either case, the spare tire can only be used temporarily, not as a normal tire for a long time.

Pacific Automobile Network] spare tires are divided into full-size and non-full-size. A full-size spare tire can be used as a normal tire, just like a normal tire; Non-full-size spare tires can only be used for temporary emergency use, not as normal tires. Tires are a very important part of the car, the tire is the only part of the car that is in contact with the ground, and the tire is related to the driving stability and driving safety of the car.

There are two types of spare tires: full-size and non-full-size. A full-size spare tire can be used as a normal tire, just like a normal tire; Non-full-size spare tires can only be used for temporary emergency use, not as normal tires.

There are two situations of car spare tires: full size: it means that the spare tire is exactly the same as the four wheels of the car and can be used as normal tires.

Non-full-size: usually divided into two situations, one is the shrinkage of specifications, such as 17 for the main car and 16 for the spare tire, but the tire circumference (diameter) is basically the same, the hub of the spare tire is small and narrow and even made of iron, but the impact is not great when used; The other is a completely shrunken spare tire, both the diameter and the hub are much smaller, and can only be used in an emergency, and the speed of the vehicle is limited when used. Spare tires are not full-size more common in European and American car series, because Europe and the United States are countries where cars are popular, and after-sales service industries such as maintenance and rescue are developed, and the popularization of small-size spare tires reduces the cost of factories and reduces the load of vehicles, and it can really be called the concept of "spare tire".

Pacific Automobile Network] spare tires cannot be used as normal tires. Because the spare tire is actually for emergency use, the spare tire is pasted with warning signs, which clearly tell the owner that it can only be used at a speed of 80 kilometers per hour, can only be used in an emergency, and is not a long-term use of the tire.

Because of the low frequency of use, less friction with the ground, and the size of some spare tires will be smaller than the size of the positive tires, its flattening rate, tire width or tire diameter are different from the normal use of tires, the friction coefficient of the four tires is different, the ground adhesion is different, the air pressure is different, and the long-term 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 other tires in the same direction produce uneven friction and other phenomena.

Non-full-size spare tires, also known as emergency tires, will be smaller than normal tires in diameter and width, far lower in compression and wear resistance than normal tires, and the body will also tilt to one side, which is not conducive to car handling. At the same time, the non-full-size spare tire has strict requirements for speed, so the maximum speed cannot be higher than 80km h, which can only be used to help the owner drive the car to the nearest repair shop. And the fuel consumption, braking, and transmission system of the car will be affected somewhat.

The spare tire is generally placed in the trunk of the vehicle, and it is generally not used to put it there, and the rubber will age after a long time, and the spare tire that has not been used can not be used as a normal tire after five years. Whether it's a full-size spare tire or a non-full-size spare tire, it's just an emergency tire. The speed level and load-bearing index of the spare tire are different from the four normal tires of the vehicle, so they cannot be used instead.

The spare tire can only be used as a temporary replacement, and the driving range does not exceed 100 km. (Photo by Chen Miaoling of Pacific Automobile Network).

Non-full-size spare tires cannot be used as normal tires, and full-size spare tires can be used as normal tires. Special spare tire is also called non-full-size spare tire, the biggest difference between the special spare tire and the normal use of the tire is that the tire size and size are smaller than the normal use of the tire, if one of the tires is flat and replaced with a special spare tire, it can only play the vehicle at low and medium speed to the nearest tire shop or repair shop to repair the tire or replace a new full-size tire. If the special spare tire is used as a normal tire for a long time, it will cause the vehicle to be more prone to puncture due to the unbalanced pressure acting on one side, and it is more dangerous if it is driving at high speed.

The size of a full-size spare tire is exactly the same as that of a normal tire, so only the kind of vehicle that uses a full-size spare tire can use the spare tire for a long time.

Hello spare tire can not be used as a normal tire, the speed grade of the spare tire is relatively low, this tire is unable to make the car at a very high speed, the width of the spare tire of many cars is smaller than the formal tire, so the spare tire can only be used in an emergency, the tire is an important part of the car, the tire is the only part of the car in contact with the ground, the tire is related to the driving stability and driving safety of the car, the tire is a rubber product, and the rubber product will be used for a long time There will be agingUnder normal circumstances, tires can be used for four years when installed on a car, so it is recommended that you replace the tires every four years.

Now a lot of spare tires are not full-size, can not be used as normal tires, can only be used in emergencies, the wheels are not the same, the tire size is not the same, should be emergency OK, normal use of the car is not good.

The spare tire can not be used as a normal tire, and the spare tire can only be used when the normal tire is broken, and the car should be driven to the auto repair shop for repair as soon as possible.

The spare tire cannot be used as a normal tire, but can only be used for short distances.

The spare tire is not the same as the normal tire, the air pressure, load index, and speed level of the spare tire are obviously different from the normal tire, just as a substitute for emergency use, and it is necessary to ensure that the transposition of the tire is correct and safe, and only the same structure and specifications of the tire can be used. Spare tire inspection is mainly to check the tire pressure and whether there is wear and tear, and replace the tire as soon as possible before the tread wears to the wear mark line. Tires are a kind of ground rolling annular elastic rubber products assembled on various vehicles or machinery, and tires are usually installed on metal rims, which can support the body, cushion external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle.

Car spare tires cannot be used as normal tires. The maximum speed when using a spare tire is lower than that of a standard tire, and it is advisable to change to a standard tire in time after arriving at the destination, which is usually marked in a prominent multi-Chinese language.

Car spare tires are divided into full-size spare tires and non-full-size spare tires. Non-full-size spare tire tires become narrower, and the corresponding ground grip is also small, light load, poor impact resistance, long braking distance, and more laborious acceleration, which can only be used as an emergency, if it has been used as a main tire, it is not only dangerous but also easy to break.

Extended Materials. Also pay attention to the skills when using the spare tire:

1. When the spare tire is installed, the drive wheel should not be installed as much as possible, so that it is not easy to deviate from the direction when driving. Front-wheel drive vehicles can be replaced with the rear wheels, rear-wheel drive vehicles can be replaced with the front wheels, and four-wheel drive vehicles are best changed to the rear wheels.

2. Remember to pump up the spare tire during maintenance, after the spare tire is stored for a long time, the tire pressure will be high and low, and maintaining normal tire pressure is also conducive to prolonging life.

3. There is no sun and rain, and the life cycle of the spare tire is very long, but it will also age naturally, and it is recommended to replace it after about 4 years. You should also check the spare tire frequently, and replace it immediately if it is cracked or damaged.

The spare tire cannot be used as a normal tire, and can only be treated in an emergency.

High yield and high risk. This is not entirely accurate, and the risks and benefits are never equal. Is it true that with greater risk, greater benefit? In the teacher's view, it is not, there is a decisive variable between risk and return, and that is ability!

When we don't have a certain ability, the risk of stepping into one thing rashly is huge. But if we are rigorously trained, the risk is much less. In reality, how many people can successfully walk a tightrope, only a small number of people, because most people do not have this ability.

How much knowledge and ability you have, how many risks you can resolve and how many benefits you can get! On the one hand, the risks and benefits arise from the objective opportunities that arise in the market, and on the other hand, from the subjective cognition and skill level of the individual. Therefore, the risks and returns of the same investment vehicle are different for different people.

An inch of time is an inch of gold, and it is difficult to buy an inch of time" Time waits for no one, every minute is precious, and time is the most important wealth in our lives. We live in time, but there are many people who ignore it, and before you know it, after a few days, some people get a lot and some people get nothing. Instead of spending your life doing nothing, it is better to seize the opportunity to add more excitement to your life.
