Why are car tires black, car tires are all black, why is that?

Because tires contain carbon black. In fact, the world's first tires were milky white, just like the color of natural rubber. At that time, tire manufacturers did not know that mixing carbon black with rubber would have such a great effect, and it could enhance the wear resistance and anti-skid performance of tires.

Now the tires produced are no longer surnamed "black". It all depends on a completely new and incredible production process: a certain amount of sand is mixed into the rubber raw material for the production of car tires, reducing the proportion of carbon black.

Of course, this is a special production process controlled by electronics and computer technology, and sand is actually the basic raw material silicon. Chemists have incorporated silicon into rubber, so they can make "whatever you want" car tires. This kind of car tires are suitable for different needs, low temperature wheels and high temperature hard.

In the presence of water, soft tires can remove water from the road surface of the tire to a minimum, so that the tire can achieve the best meshing with the road surface. Rigid tires are ideal when the road surface is dry, and during driving, the rubber molecules in the rigid tires oscillate rapidly at different frequencies depending on the driving speed, and the vibration frequency is very different at 120 km/h compared to 240 km/h. As the speed of the vehicle changes, so does the frequency of the vibrations of the rubber molecules.

The role of silicon in rubber is to control the vibration frequency of rubber molecules and adjust the tire from soft to hard, or from hard to soft. This "controllable tire" solves many of these difficult and contradictory problems for tires. This is an epoch-making progress in the history of automobile tire manufacturing.

Later. The color of the tires will also be colorful, and they can be matched with the same color as the body according to the owner's wishes.

If you look closely, you'll find that no matter how the vehicle changes, or how cool the body is, the tires on the car are still the same black, why is that?

In order to improve the performance, the tire rubber is added with carbon black, which is wear-resistant and anti-aging.

Combined with the requirements for tire wear resistance and driving visual safety, the current better color option than car tires is black. However, it is not excluded that with the development of science and technology and the exploration of new materials, the phenomenon of a single black tire will be broken in the future, so that the tire will be colored, customized privately, and more personalized, and the structure of the change is somewhat similar to manual change. Multiple wheels are made up of a combination of gears with different gear ratios.

The engineering department has very high engagement and transmission efficiency, and most transmissions have a high speed range. However, due to the limitations of the volume and production process, the number of transmission gears is not too high, therefore, the engine cannot always be maintained at the ideal speed.

<> pure rubber tires are not wear-resistant, and the rubber molecules will change with the change in vibration frequency. For heavy-duty tires such as automobiles, pure rubber tires have a very low lifespan. In order to solve this problem, after years of research and testing, these companies finally chose black carbon as the most important substance in the formulation, which can stabilize the rubber molecules and improve the service life, slip resistance and wear resistance of tires.

In the first stage, the tire color is white. Later, white tires became popular for a while. However, due to aging and difficult maintenance, it can cause discoloration. As a result, black tires later became mainstream.

The reason why tires are black is mainly due to the addition of carbon, which causes tires to be black. The reason for adding carbon is that it can increase the wear and service life of tires.

In addition, starting with the color, black tires are more versatile, even if the tires are colored, there is no stipulation that the wheels should be black, considering the correspondence between the tire formula and the body color. The reason why tires are black mainly depends on the production process. Currently, most tires contain black carbon.

Black carbon can actually improve the life and wear resistance of tires, so tires will turn black. After diffusion of other stable substances such as silicon in the future, the tire will change another color. At first, the car tires are white or the natural color of rubber, but natural rubber is not wear-resistant, in order to increase the wear resistance of the tire, graphite or carbon black is added when the tire is vulcanized to increase the wear resistance of the tire.

Because carbon black is added to the tires, it is not only wear-resistant, but also resistant to ultraviolet rays and prevents ultraviolet rays from damaging the tires, so it is black.

Because car tires are used for a long time, and the wear is particularly serious, if it is other colors, it may be very undurable, and black car tires are not only durable but also particularly dirt-resistant.

The reason is that black tires are more resistant to dirt, and the problem of black tires bursting again is easy to solve.

<> "Now the car tires we see on the road are all black, so have you ever thought that car tires are black from the beginning?" Why aren't there other colored tires?

1. What color was the car tire at the beginning?

We all know that car tires are made of rubber, and natural rubber is white, so the tires made of rubber at the beginning were white, but I didn't expect it.

But natural rubber is too soft, poor wear resistance, and low hardness, so the service life of tires is far less high than that of today's black tires.

Later, in their research, they found that adding carbon black to rubber can increase the hardness and wear resistance of rubber, and the life of tires can be increased several times.

Since then, the tires have all turned black.

2. What are the benefits of black tires?

1. Just like dressing, black is versatile.

2. Other colors are too bright, which is easy to induce dazzle and cause traffic accidents.

3. The pure group tires are always in contact with the ground, and the black tires are dirt-resistant.

Do you guys know any other benefits of black tires?

<> "Car tires were white at first!

In fact, car tires were not black at first, but white! Because tires are made of rubber, while natural rubber is white. After a long time of pure rubber tires, the rubber will turn yellow and age, which is not only ugly but also durable.

Later, it was found that adding black "carbon black" to the rubber can greatly enhance the anti-aging and wear resistance of the tire, and so far, the black tire has appeared.

Colorization of car tires: a beautiful misunderstanding!

It is human nature to love beauty, just like people wear shoes, wearing only black will inevitably look monotonous and boring. The same goes for car tires, and tire manufacturers have been experimenting with various ways to make colorful tires, and this kind of exploration has not stopped since the advent of car tires.

Just start using the soil method: paint.

In the thirties of the 20th century, cars were a symbol of wealth and social status, and many owners painted white paint on the outside of their tires to make the car look more stylish. However, after the white paint is peeled off for a long time, it is very good-looking, and it needs to be painted frequently.

Eclectic method: add the word before the spike or ring belt.

Evolution: Added anti-aging agent and color reinforcing agent.

In 1997, Michelin France launched the "Rainbow" series of tires, which came in three colors: red, green and yellow, which attracted some fans to buy.

In 2002, there was also a domestic tire manufacturer called "Double Star" to follow up and launch Double Star color tires, and the manufacturer officially announced that the performance of its color tires was better than that of ordinary tires.

Why are car tires mostly black?

It stands to reason that colored tires have also been manufactured, and their performance is good in all aspects, but why are most of the car tires still black?

The reason is simple: "Colored tires are not cost-effective, unsafe, and unnecessary"!

Not cost-effective. Black tires are cheaper! According to the current manufacturing process, black tires are currently the most cost-effective, which can better balance the performance of tires and **.

Insecurity. Black tires are safer! Colored tires are easy to attract attention when rolling, and even give people a dazzling and dazzling feeling, which is not conducive to safe driving.

Not necessarily. Cars have already entered thousands of homes, and they are not an uncommon item, and there is no need for Sib to increase his chances of turning heads with brightly colored tires.

We all know that the main component of tires is rubber, and we also know that tires are black, but the question is, why are tires black? Not white, green, red......Or is it colorful? In fact, the color of tires is mainly determined by the additives used in the production of tires.

Back in the 19th century, the tires were actually black 919 Ford Model T.

As early as the 19th century, the color of rubber tires was not fixed due to different additives. By 1915, the addition of carbon black, also known as soot, to tires gave rubber an ink-like black color and an unprecedented level of wear resistance. After that, rubber tires entered a long period of black dominance.

In the 50s of the 20th century, the outer wall of the tire began to be painted with white paint Dawson Berg from the movie "The Great Gatsby".

But the black tires did not last to this day, and there were some hiccups in between. In the 50s of the 20th century, as the automobile became a symbol of wealth and social status, the outer side walls of many car tires were painted with white paint to show their personality and be different. If you've seen the movie "The Great Gatsby", you'll have some impressions.

However, the biggest disadvantage of this tire beauty method is that after the tire is used for a period of time, the paint will gradually peel off, which is very impressive, and this method is gradually neglected.

In the 60s, white rubber tires were revived, but they were not used but in the 60s, some car manufacturers began to use white rubber tires, but the strength and tear resistance of this tire are poor, the aging resistance is poor, and the cost is more expensive.

In the 80s, white lettering appeared on the outer wall of the tire and the inner ring of Cadillac, the car of Elvis Presley.

In the '80s, developed countries such as Japan, Germany and the United States reproduced tires with white lettering or ring bands, and Goodyear even designed a fully transparent tire that could be illuminated at night.

In the 90s, the tire technology revolutionized, and the tire color was arbitrarily colored.

However, in the 90s, Michelin cooperated with a French chemical group to replace carbon with silica, and achieved good results. Since the inherent color of silica is white, any different dyes can be added, so that the tire can choose any color.

Nowadays, the proportion of black tires is determined by cost and demand, and the main component of most tires today is rubber, of course, it is also divided into natural rubber and synthetic rubber, the quality of natural rubber is better, and synthetic rubber is mainly for cost considerations. The reason why the tires are still black today is because of the carbon black inside, and secondly, it is still due to the consideration of manufacturing cost and demand. Colored tires are not in high demand.

As early as the nineteenth century, the color of automotive rubber tires was not fixed due to different additives. By 1915, the high-temperature condensation of carbon and hydrocarbons had given rubber an inky black color and an unprecedented level of wear resistance. After that, rubber tires entered a long period of black dominance.

In the twentieth century.

In the thirties and forties, in order to show their wealth and social status, many foreign car owners painted the outer side walls of tires with white paint to distinguish them from others and reflect their individuality. However, the biggest disadvantage of this tire beauty method is that after the tire is used for a period of time, the paint will gradually peel off, the sidewall will be mottled, and it will be very beautiful, and this method will gradually be neglected.

In the 60s of the 20th century, the use of white rubber white rubber tires have seen a recovery, but the strength and resistance to tearing performance of this tire is poor, the aging resistance is poor, the cost is more expensive, the use of a little longer, the rubber will slowly turn yellow and brown, lose the original decorative effect.

In the 80s, developed countries such as Japan, Germany and the United States reproduced tires with white lettering or rings on the sidewall, and Goodyear in the United States even designed a fully transparent tire that could be illuminated at night. In the 90s, Michelin partnered with a French chemical group to replace carbon with silica with good results. Since the inherent color of silica is white, you can add any different dyeing agent to the tires, and you can choose any color from now on.

In recent years, with the emergence of new rubber anti-aging agents and white and light-colored rubber reinforcing agents, the development of decorative tires has been further promoted. However, in any case, colored tires can only be used as decorative tires, and their cost and performance are still not comparable to black tires that have been used for decades.
