It is said that the spare tire cannot be used as the main tire, so why not replace the spare tire wi

Some vehicles are equipped with full-size spare tires, that is, they are exactly the same as the four tires of the vehicle, and some are smaller, so the spare tires can travel for a long time, but the spare tires of models such as American cars and Buick are all tires with a large gap in width and narrowness, and the tires with the T starting signal are not able to travel long distances. 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.

Because even if you change the spare tire to the same as the main tire, it will wear out if it is left outside for a long time.

Because if you change to the same as the main tire, the burden on the car will be very large.

Because the main tire occupies a place, and it is expensive, it is not convenient, and the specifications are not the same.

If the spare tire is replaced with the same as the main tire, the cost will be higher.

It is exactly the same as the four tires of the vehicle, and some are one size smaller, so the spare tire can travel for a long time.

The spare tire is only used temporarily in the event of an accident, and it is not necessary to be so high-spec.

Because spare tires are generally used in emergencies, it is a bit wasteful to use the main tire.

The cost will be relatively high, and it will wear out if it is left outside for a long time.

The specifications and construction of small size spare tires are different from those of normal tires in the car.

In order to save costs!!

Changing to a main tire is also not commonly used, because the wear is not the same.

My car is Haval H5 Classic Edition 2017 top four-wheel drive + differential lock, spare tire full size, original Magis 235 65 R18 106V M+SThe HP is exactly the same as the other four tires in use. After the tire rotation is used, the wheel is completely matched, and the four-wheel electronic pressure measurement has no abnormality.

Spare tireIt can be used as a normal tire. The spare tire is the same as a normal tire. The spare tire is originally a normal tire, and it is just used as a replacement after the normal tire is broken.

A spare tire is actually an emergency tire, not a tire for long-term use. Regardless of whether the spare tire is wide or narrow, the manufacturer has special requirements for production and use.

Type of spare tire. 1. Full-size spare tire: The size of the full-size spare tire is exactly the same as the other 4 tires of the original car, and it can be replaced with any temporary or unusable tire.

2. Non-full-size spare tire: The diameter and width of this spare tire are slightly smaller than the other 4 tires, so it can only be used as a temporary replacement, and can only be used for non-driving 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 commonly known as "run-flat tires", which is literally translated as "run-flat tires" in the industry. Compared to regular tires, zero-pressure tires do not leak or leak very slowly after being punctured, maintain the driving profile, and the bead can be fixed to the rim at all times.

, so as to ensure that the car can be driven to the pit for a long time or temporarily.

No. Whether it is a full-size spare tire or other types of spare tires can not be used as normal tires, because the spare tire is used in an emergency, although the full-size spare tire is exactly the same as the normal tire size, but it is not the same as the normal tire wear degree, the spare tire is not often used, so the spare tire is almost not worn, and the original tire is perennial driving, its wear degree is greater than the spare tire, which makes the tire heat dissipation, braking, acceleration, drainage and other aspects are different, long-term driving is easy to lead to deviation.

Notes:The cost of a size spare tire is usually relatively high, which will increase the cost of buying a car. The tire width of the non-full-size spare tire is smaller than the original car tire, and the weight is light, the vehicle occupies less space, which can reduce fuel consumption to a certain extent, so as to get more power, in addition, although the non-full-size spare tire is smaller, it can save the cost of the car manufacturer, but it is also reminding the driver to repair or replace the tire in time to avoid the potential driving safety hazards caused by the long-term use of the spare tire.

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.

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.

Non-full-size tires cannot be used as normal tires.

The reason is to reduce the weight, reduce the footprint, make it easy to distinguish between normal tires and spare tires, and most importantly, remind everyone to remember to replace with repaired normal tires. Therefore, non-full-size tires cannot be used as normal tires. It feels like the tire width of a full-size spare tire is the same as that of a normal tire, but it does not mean that all its parameters are exactly the same as that of a normal tire.

Such as: tire texture, speed level, load-bearing index, etc., if the above parameters are different, there is no way to use them together, and it is not very safe to drive at high speed.

Precautions for spare tires

1. Regularly inspect the spare tire.

During daily maintenance or before long-distance travel, few car owners test the spare tire, and some unprofessional repair shops often ignore this. 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. If there is a small crack on the sidewall, you can't use it for long-distance or high-speed driving, because the tire sidewall is thin, and high-speed driving is prone to punctures.

2. The oil and the spare tire are not put together.

The main component of tires is rubber, and the rubber is most afraid of the erosion of various oils. Car owners often store lubricating oil and other oils in the trunk, once these oils get on the tires, the tires will swell and erode, which will greatly reduce the service life of the tires. If the tires are stained with oil, rinse off the oil with a neutral detergent in time.

No, you can only temporarily save the emergency, and most of the spare tire models are not full-size, narrower.

The spare tire of the car is generally replaced once every 3-5 years, so let's go to see why with life.

First of all, a spare tire lasts almost twice as long as a car tire. "Tires can last for years" is a question that almost all car owners ask when changing their tires. This simplicity uses time as a cycle criterion.

Many tire manufacturers and ** recommend replacing within 3-5 years. The main reason is the aging cycle of rubber, the main raw material for automobile tires. Generally speaking, during the life cycle of tires, the aging of rubber caused by the vehicle environment can cause the rubber to harden and crack, and the main culprit is ultraviolet rays.

Where is the strongest UV rays in life? - Nature is under the sun! Under ultraviolet radiation, rubber gradually loses its elasticity and toughness and gradually becomes fragile.

Eventually, it will age and crack.

Secondly, if you want your tires not to age, it's simple: dry, ventilated. Rubber ages very slowly, to the slightest degree!

That's why rubber products stored in specialist vaults are still similar to new after 3 years. The storage of tire manufacturers is carried out in accordance with the requirements of anti-light, anti-drying and anti-ventilation. Even if the tires have been stored for a year or two, they can continue to be used for 5 years, and the service life is still calculated as "after the tires are installed in the vehicle".

The spare tire "sleeps" in the dark spare tire groove all year round, which basically blocks the direct exposure of ultraviolet rays. Although there is no ventilation and constant temperature, it is very good for the preservation of rubber. In the consistent experience of the eldest brother, there are many people who think that it is normal for a spare tire to be 5 years, and see that a spare tire of more than 12 years can be used below.

Finally, the spare tire actually does not need to be changed, because it is not needed in ordinary times, and it is needed at critical moments. For most car owners nowadays, the spare tire can be said to be a tedious configuration. A long time ago, there were very few 4S shops and car repair shops due to poor road conditions.

At that time, the spare tire was equipped, and the five wheels were the same, and they could continue to be used after replacing the original wheels.

To sum up, I believe you already know whether the spare tire of the car needs to be replaced regularly.

1.Spare tires need to be replaced regularly. As a "lifesaver" in an emergency, spare tires must always be in good condition, so they need to be checked and replaced regularly.

2.Spare tires age naturally when not in use. Pay attention to check the service time of the spare tire. The service life of a spare tire is usually 4 years.

3.Check the spare tire tread compound for aging, pattern wear and tire wall cracks.

4.Check your tyre pressure regularly. If you find that the spare tire is deflated when you need it, you can't use it.

5.Be careful not to let the oil come into contact with the tread to prevent the rubber from corroding.

The spare tire of the car does not need to be replaced regularly, because the spare tire is only used when our original tire is damaged, and there is no need for him to replace it.

The spare tire of the car also needs to be replaced regularly, and the spare tire of the car will usually experience wind and sun, and the spare tire will also have great wear and tear.

Is the spare tire the same as the original tire? The spare or shouting tire is not the same as the original tire, only the size of the full-size spare tire is exactly the same as the original tire. The role of tires:

1. The operation of the car is realized by the transmission of driving force, braking force and steering force through the tires; 2. Supporting the vehicle load; 3. Reduce and absorb the vibration and impact force of the car during driving, and avoid the damage to the auto parts due to the violent shock and backlash. The maintenance methods of tires are: 1. Clean the stones in the tire gaps regularly; 2. Reduce tire exposure; 3. Detect the tire pressure in time; 4. Pay attention to the maintenance of suspension; 5. Regularly check the front wheel alignment; 6. Pay attention to the driving mode, choose the road surface to drive while driving, avoid objects that can puncture and scratch the tires, and avoid the corrosion of tires by chemical residues.

No, the spare tire can only be used temporarily.

A spare tire is actually an emergency tire, not a tire for long-term use. Regardless of whether the spare tire is wide or narrow, the manufacturer has special requirements for production and use. Because the spare tire is not hung on the car for a long time, there is no wear, so a tire without wear and a tire that has been worn out is not the same, and the spare tire itself has certain safety hazards when used in the car.

In the process of use, the user cannot replace the original tire with a spare tire because the car has run for several kilometers. Because the production time of the spare tire and the original tire are different, the tire aging, hardening degree, life and deformation are different, so it is not safe to use it for a long time. The spare tire should be replaced with the original tire in time after emergency use.

Hello, this depends on the situation, that is, the spare tire style of the vehicle is equipped, some vehicles are equipped with full-size spare tires, that is, the four tires of the vehicle are exactly the same, and some are one size smaller, such spare tires can run for a long time, but the spare tires of models such as American cars and Buick are wide and narrow tires with a large gap between width and narrowness, and the tires with the T head signal, such spare tires cannot be driven over long distances.

Car spare tires are divided into: full-size spare tires, commonly known as standard spare tires, are the same as four tires, can be used as the main tire, and there is a non-full-size spare tire, which can only be used as an emergency spare tire, prohibiting long-term use, and when using a non-full-size spare tire, the speed of the vehicle is best controlled at about 80 yards.
