Is the explosion-proof tire good or not?

In fact, many people are familiar with explosion-proof tires. The scientific name of the explosion-proof tire is "run-flat tire", and the logo is RSC. Generally, the sidewall of explosion-proof tires will have RSC logo. The function of the explosion-proof tire lies in its thick sidewall. When the RSC tire loses pressure instantly (such as a puncture), it can also support the car to drive with the thick sidewall, so as to save the car from losing control of the steering wheel due to a puncture (within a certain speed). A flat tire is undoubtedly a fatal blow to a high-speed car. If the speed exceeds 120, the survival probability of people in the car is extremely low (the death probability exceeds 160, 100%), so safe driving is the premise of safe driving.

Explosion-proof tires are synonymous with safety and high-end at present. In fact, there is no special difference between the explosion-proof tire and the ordinary tire in structure, except that a thick reinforcing layer is made on the sidewall of the tire, which makes the tire still stand in the state of deflation or air leakage from the nail. Compared with ordinary tires, this kind of tire is stronger and harder, and the key is the strong deformation resistance of the tire wall. Moreover, even if there is air leakage, the solid sidewall can ensure that the tire is almost not deformed, so it can continue to drive for a certain distance (some brands claim to be able to drive 250km at a speed of 80km/h).

However, everything has two sides. The advantages of explosion-proof tires have been mentioned above. What are the disadvantages of this kind of tire? The answer is definitely yes. You can't have your cake and eat it.

Disadvantages of explosion-proof tires: firstly, due to the reinforced design of the tire wall, the tire is hard as a whole, which reduces the absorption of vibration by the tire when the car is driving, and then directly transmits it to the chassis for filtering, resulting in a certain decline in comfort, so the tire will be worse than ordinary tires; At the same time, because the sidewall of the explosion-proof tire is very hard, the shock and impact that should be absorbed by the tire are handed over to the shock absorber and other parts of the suspension to bear, which may shorten the life of the suspension system over time.

Secondly, the tire noise of explosion-proof tire is relatively high, which is directly related to its structure. Tire wall thickness and hardness will inevitably have noise when driving. We can compare the silent tires in ordinary tires, and the driving experience of changing into silent tires is definitely different from that of explosion-proof tires, because the sidewall of silent tires is thin; Because the tire wall is thick and hard, it is difficult to repair once it is punctured. Many car companies give the statement that "only new tires can be replaced". In real cars, the cost of replacing new tires is too high, and the frequency of puncture is not fixed, so many car owners will take measures to repair tires. After the explosion-proof tire was repaired, there was no other problem, but the tire noise increased slightly.

Third, the price of flat tires is generally higher than that of ordinary tires. In addition, even if you don't care about the price, you may not be able to buy the right model, because the tyre size is not very complete; The service life of explosion-proof tires is also a reference to the degree of tire wear, and it will not be longer than ordinary tires because of structural differences, so the majority of cars mainly pay attention to it.

Not everyone can use explosion-proof tires! Wrong installation has such an effect?

Like a flat tire

That's really a very dangerous thing.

Especially on the expressway.

A flat tire usually leads to a serious accident.

This is because the tire of the car body is flat.

Will tilt because they lose their original center of gravity.

Most of my friends have no experience in dealing with flat tires.

So it is easy to produce misoperation.

It is easy to cause serious accidents such as vehicle out of control and rollover.

With the development and progress of science and technology

Automobile tire technology is also developing continuously.

And the birth of explosion-proof tires.

But what is an explosion-proof tire?

We have to see what ordinary tires look like first.

Most of our family cars

This is a radial tire.

Most of these tires are made of natural rubber.

And renewable energy glue.

Generally, the tire wall is thin.

In the case of a flat tire,

It will cause the center of gravity of the corresponding side to sag and lose balance.

Explosion-proof tires are made of different materials.

In addition to the original shape of ordinary tires

The explosion-proof tire is on the sidewall of the tire.

Added a layer of renewable natural rubber with nanotechnology.

Because of its high density.

It is much stronger than the sidewall of ordinary tires.

Even if the tires have no air pressure.

Its side wall can also play a certain role in supporting the car body.

This will not make the center of gravity of the car body lose too much.

A lot of people say that.

Zero tire pressure tire for continuous driving

But for this kind of tire,

There are always some misunderstandings between friends.

The first is this kind of tire that can run with zero tire pressure.

It's not that you don't need to cheer up.

The second is that there is no possibility of a puncture.

Only its side walls are more supportive.

Even if one tire leaks.

It won't fall apart.

Your body won't lean too much.

Thereby reducing the misoperation probability of the driver.

And even if the tire is punctured by a nail, it will leak.

Explosion-proof tires will not produce tires.

Excessive damage caused by rolling.

But don't get too excited yet.

Explosion-proof tires with so many advantages

Not suitable for all car installations.

It also has some shortcomings.

Firstly, it is due to the reinforcement of sidewall materials.

Will lead to harder than ordinary tires.

If your car doesn't have this configuration at the factory.

Blind installation of explosion-proof tires

Will affect the shock absorber and suspension system.

Produce more impact and wear.

Affect the service life of suspension components.

And it will feel very hard on the road.

For comfort, there are some deductions.

Besides, this kind of tire is relatively heavy.

This will also increase fuel consumption while driving.

So if you are interested in this kind of tire,

Then you need to check the configuration of your vehicle carefully before replacing it.

Or consult a professional tire changer in detail.

Avoid unnecessary damage to the vehicle!

What is an explosion-proof tire? The exact name of "explosion-proof tire" is actually called driving stability control, abbreviated as RSC. There is no word "explosion-proof" in this name, so it is actually a misunderstanding for everyone to regard it as an explosion-proof tire.

Because the probability of puncture of run-flat tires is much less than that of ordinary tires, coupled with the misleading propaganda of some merchants, everyone associates run-flat tires with "explosion-proof".

How can I tell a flat tire? If we only look at the appearance style, it is actually difficult for us to tell whether it is a normal tire or a flat tire.

Because a run-flat tire is exactly the same as an ordinary tire, it also has tire essential elements such as tread pattern, dimensional parameters, tire pressure standard and inspection label.

Different brands of run-flat tires have their own English product abbreviations, which are usually marked on the side of tires as a sign to identify run-flat tires from the appearance.

What does a flat tire do? When an ordinary tire encounters a puncture, the tire will collapse instantly, unable to support the vehicle to continue driving, and even tear like a piece of paper under the cutting action of the hub; Run-flat tires can ensure the integrity of the carcass to the greatest extent, avoid the vehicle from losing control, and continue to support the vehicle for a certain distance.

Take the run-flat tires equipped by BMW as an example. In the case of a flat tire or a flat tire, the vehicle can still travel 250 kilometers at a speed of 80km/h, which can support the vehicle to the repair shop.

It sounds quite safe, but I still want to emphasize that although the probability of puncture is small, the risk still exists.

The probability of puncture is small, but the risk still exists.

If the tire is seriously damaged (for example, the wound caused by foreign objects is too large, the tire is violently hit, and the tire is corroded). ), the characteristics of a flat tire will be like a cloud, and the vehicle will get out of control. Everyone had better drive safely.

What are the disadvantages of a flat tire? Although I have said so many advantages, there are actually several inevitable shortcomings in a flat tire.

One is that the use of run-flat tires needs to match the appropriate suspension system, which is due to its high hardness. The direct impact of high tire hardness is to reduce the comfort of the vehicle, which will be more obvious in the actual driving process.

The other is that it is more difficult to change tires. With the current equipment and technical level of domestic tire shops, it is not easy to disassemble and assemble a run-flat tire.

The weight of run-flat tires can not be ignored-the weight of each run-flat tire is about 3kg more than that of ordinary tires with the same size and specifications. Although there is no need for the owner to change the tires, the tires are hard and heavy, which is really hard for the tire maintenance master.

Summary: The safety factor of run-flat tires is much higher than that of ordinary tires, and vehicles equipped with such tires can really make people feel at ease.

However, the shortcomings of run-flat tires are equally prominent, that is, they sacrifice some comfort, require higher suspension, are more expensive, and are difficult to maintain.

Moreover, at present, the technology and product specifications of run-flat tires are not fully mature, and this kind of tires is still an expensive commodity consumed at a niche level. It is not necessary for ordinary car owners to deliberately pursue or blindly follow suit.

It is more useful to develop good car habits and pay attention to tire maintenance than to replace "explosion-proof tires".

Automobile explosion-proof tire, as a new type of automobile tire derived from ordinary tire, was originally applied in military field, and gradually began to be used for civilian use, and gradually became exclusive to high-end luxury cars. However, in recent years, due to the gradual maturity of its manufacturing cost and technology, the price began to decline, and it was gradually applied to some mid-level cars, and many consumers began to understand this kind of explosion-proof tire. But is a flat tire really that good? Many consumers have encountered many problems in the process of using flat tires, and many consumers are still confused about the identification of true and false flat tires. Let's really understand the flat tires that have appeared in our lives in recent years.

What is a flat tire?

Automobile explosion-proof tires are not really explosion-proof, but they can still support driving to the repair and rescue point in the case of air leakage and puncture of automobile tires, and there will be no out-of-control situations such as rollover caused by the sudden drop of automobile tire support at high speed. Explosion-proof tires are also known as run-flat tires in the official scientific name, and most of the configuration tables of many cars are equipped with this name. In fact, many times the tire has a puncture, and the puncture point is at the junction of the tread and the sidewall. At this time, the tires lost support, and the front wheel data supported the whole car out of control. Because it is necessary to provide some support at the moment of tire puncture, the tire wall is thick, and multiple layers of fibers are implanted in the manufacturing process of NTD to improve its support. Also, because the tire wall is relatively hard, it is necessary to add some flexibilizers during manufacturing to make it full of toughness.

Due to the hard sidewall and strong support, the explosion-proof tires have lost their shock-absorbing comfort to a certain extent because of the excessive use of large flat rate design for blasting, while luxury cars generally have strong suspension systems, which are naturally not sensitive to the loss of tire shock-absorbing characteristics, so they are more common in luxury cars.

Explosion-proof tire is different from ordinary vacuum tire, and has electric control components such as outer tire, inner tube, spare tire inner tube, gas generator and pressure sensor, which also makes its cost higher than ordinary tire.

Car puncture, distinguish between true and false

It is precisely because of the high cost of car puncture that consumers need to pay higher costs for matching the puncture. Naturally, many unscrupulous merchants will also sell ordinary tires as flat tires, and even produce fake flat tires. The identification of fake and inferior flat tires requires the use of professional instruments such as hardness tester, so in order to put an end to this phenomenon, consumers had better go to professional tire shops or 4s shops to replace them.

There are usually two ways to distinguish between ordinary tires and flat tires:

Method 1: Identify the specification sequence symbols of automobile tire side. Ordinary tires do not have the specifications of red envelopes, and each manufacturer has different specifications for these symbols, which are used for anti-counterfeiting. If unscrupulous traders print these symbols later, consumers can recognize them by touch. The symbols caused by twins are difficult to touch. Manufacturers generally use explosion-proof signs: Pirelli R-F, Mabel SSR, Bridgestone RFT, Michelin ZP and Deng Lupu ROF.

Method 2: From the hardness of tire wall, the tire position of bare tire is thick and hard, which is difficult to be pressed by thumb, while ordinary tire can achieve the same hardness even if it is hardened by vulcanization, but the surface color and tread color can be obviously different.

Is it necessary to modify the explosion-proof tires of automobiles?

As ordinary consumers, is it necessary for our compact family model to modify explosion-proof tires? As a kind of functional tire, explosion-proof tire has certain advantages in the safety and reliability of high-speed driving, and its wear resistance is better than that of ordinary tire because of its hard tread. However, automobile explosion-proof tires are not dominant in comfort. If your car has no professional training in suspension, it is best not to modify explosion-proof tires.

Luxury models are not equipped with explosion-proof tires in the original factory. In the later stage, you can choose explosion-proof tires through 4s shops, but be careful not to have too large flat rate, because the domestic road conditions are different, and the explosion-proof tires with too large flat rate are easy to be damaged, especially on the road surface passing through some gullies and ridges, which will be damaged by some impacts.

A flat tire is not everything.

Twins have expertise, but not everything. What are his shortcomings?

First of all, it is inconvenient to maintain, because the tire wall of explosion-proof tire is relatively thick, which can not be completely disassembled by ordinary tire machine, and professional instruments are needed to disassemble it. Moreover, after a flat tire is damaged, if ordinary tires are replaced, because the four tires have different lateral supports, the car will have abnormal handling when driving in corners, so many luxury cars equipped with flat tires are not equipped with spare tires. And tire shops in some areas have no flat tires.

Secondly, some sports cars will affect the handling because of the large dead weight of the flat tire and the unsprung weight. And it is easy to be damaged when driving on some bad roads. The most ideal road surface for flat tire is expressway, and its design essence is to prevent accidents such as rollover due to air leakage when driving at high speed.

How much is a flat tire?

The price cost of a flat tire is generally 1.5 times that of ordinary tires. Such a high price also requires maintenance during daily driving. Only by maintaining the tires can we save our lives when necessary.

First of all, clean up the stones and other sundries in the cracks of explosion-proof tires in time. Secondly, when washing the car, try to use less detergent with oxidizing substances to clean the tires. Then, although the damaged explosion-proof tires can provide a mileage of about 100 km, they should be repaired and replaced in time. Finally, the running life of automobile explosion-proof tires is longer than that of ordinary tires, but attention should be paid to replacing them in time.

Technological things can always bring us a safer use environment, and a flat tire will certainly contribute more to our travel safety.

Compared with ordinary tires, explosion-proof tires have their own advantages, but they also have disadvantages, which require comprehensive customer service of other automobile systems.

The so-called puncture is actually a flat tire. Flat tire is a popular folk saying. A puncture can't prevent a puncture. Because it has extra support on the sidewall, it will reduce the risk of losing support when the tire leaks. In addition, a flat tire can travel at a speed lower than 80km/h in the case of a flat tire.

Disadvantages of flat tires:

1, poor comfort.

2, tire repair has special requirements.

3. Replacing a flat tire requires specially designed wheels.

4. Explosion-proof tires need specially designed suspension system.

So if the original car is not an explosion-proof tire, it is not recommended to change it into an explosion-proof tire!

Are explosion-proof tires really explosion-proof?

What are you most afraid of driving on the expressway? An experienced old driver will say: I am most afraid of a flat tire. According to the data, 70% of the accidents in expressway are caused by puncture, and when the speed reaches 160 km/h, the survival rate of people in the car is almost zero. So a flat tire is the first killer at high speed. Do you have a tire that won't burst? The answer is yes, this is the legendary explosion-proof tire. Today we will talk about it.

Look at a few pictures first: high-speed puncture

Isn't it terrible? Of course it's terrible, that's terrible! So why does the tire get out of control after a flat tire?

Because when a tire bursts, one side of the tire suddenly loses air pressure, and there is no air pressure support inside the tire, it will collapse immediately, and the adhesion between the wheel and the ground will weaken or even disappear quickly, and the car body will tilt to one side, resulting in an immediate change in the center of gravity of the vehicle, and the steering of the car will immediately deviate to one side, and serious deviation will occur due to uneven adhesion of the wheel when braking. Especially for front-wheel drive vehicles, the instantaneous shift of the center of gravity after the tire burst is likely to make the vehicle out of control.

All this happened in an instant, and the driver on the high speed couldn't react at all, so the car would quickly get out of control, hit a roadside obstacle or even roll over directly, and the occupants in the car would be greatly injured or even killed. So a flat tire is a very dangerous traffic accident. In order to prevent this kind of accident, the puncture came into being.

What's a real flat tire like?

But the real "explosion-proof tires" are military off-road armored vehicles with 6 6 and 8 6 tires. Their tires are designed with special metal strips, which can keep the tires from deforming even if they are punctured by artillery shrapnel and continue to move forward.

For example, the following one.

And this.

This is the real flat tire. If our people also use this kind of tires in cars, then the safety is there, but can we afford it?

So what do we call a flat tire every day?

In fact, "explosion-proof tire" is just a nickname. The real scientific name of this kind of tire is flat tire.

What is a flat tire?

The scientific name of explosion-proof tire is "run-flat tire", and the English abbreviation is RSC. From the literal meaning of the scientific name, it can be seen that it can continue driving (80km/h 60-80 km) in the case of flat tire and air leakage.

Will the puncture not stop?

The explosion-proof function of explosion-proof tires is exaggerated by automobile manufacturers, and explosion-proof tires are not without puncture. Explosion-proof tire can be simply understood as strengthening the sidewall thickness of the tire, supporting the weight of the car, and running at a considerable speed when deflated.

Structural differences between explosion-proof tires and ordinary tires

The main feature of explosion-proof tire is that a thick layer of natural rubber is added to the tire sidewall, which greatly enhances its firmness;

A flat tire will give the car a very tough and supportive sidewall and restore control, so a flat tire will also burst, but the car is easier to control when it bursts.

There is also an explosion-proof tire structure in which a special support ring is made inside the rim. When the tire loses pressure, the inner support ring plays a supporting role to ensure the normal running of the vehicle.

Advantages of explosion-proof tire

1. Tire burst can realize a safer "tire burst" mode when a tire burst occurs at high speed, but it cannot be avoided;

2. Anti-puncture tires can prolong the deflation time after tire puncture. After an accident, a flat tire will not run out immediately, because the tire structure of your own tire is different, even under the condition of zero tire pressure, it can help you continue driving for a certain distance under the condition of air leakage;

A flat tire is more durable than ordinary tires. Due to the reinforced inner wall structure inside the explosion-proof tire, its service life is longer than that of ordinary tires.

Disadvantages of explosion-proof tires

1

Due to the reinforced design on the tire wall, the comfort of the tire will be worse than that of ordinary tires;

2

Because the sidewall of the explosion-proof tire is very hard, the shock and impact that should be absorbed by the tire are handed over to the shock absorber and other parts of the suspension to bear, which may shorten the life of the suspension system over time;

three

Because the tire wall is thick and hard, once it is punctured, it is difficult to repair it, let alone by hand, and even it is a bit troublesome for the machine to pull the tire off the hub. If the operation is not good, it will cause irreparable damage to the tire wall;

four

The price of flat tires is generally higher than that of ordinary tires. In addition, even if you don't care about the price, you may not be able to buy a suitable model, because the leak-proof warranty in tyre size is not complete.

Which cars are using flat tires?

1, all BMW models

2. Volvo 60

3. Ford S-MAX

4. Volkswagen R36

Can all cars be fitted with explosion-proof tires?

Theoretically, all cars can be equipped with explosion-proof tires, but due to some special structures of explosion-proof tires, there are certain requirements for vehicles.

0 1

Run-flat tires are harder than ordinary tires and have higher requirements for vehicle suspension, so the suspension of vehicles equipped with run-flat tires is specially adjusted. If ordinary vehicles are equipped with run-flat tires, it is easy to damage the shock absorber.

02

Due to the characteristics of run-flat tire, it is harder than ordinary tire, but it will become more rigid in low temperature environment, which directly leads to the decrease of tire grip.

03

In order to prevent the run-flat tires from falling off the wheel hub under the condition of zero tire pressure, these tires should be installed on the rim of EH2 or EH2+, so ordinary rims cannot be equipped with run-flat tires.

Lao Hou commented:

A puncture tire, a deified tire, seems to have it and can drive without worry, but it is not. First, explosion-proof tires are not really explosion-proof, but even if they don't explode, there are certain requirements for speed. If you exceed the prescribed speed, an accident won't save you. Therefore, driving safely, not speeding and obeying traffic rules are the safest ways. Other factors can only help you reduce the chance of accidents.

A flat tire is definitely necessary. Safety first, I feel the tire noise and comfort are not bad. The horse brand I used to use is now Pirelli, which has a good grip.
