It was later realized that the first tire in the world was white. Because the tires are made of rubber.

White is the natural color of rubber

In 1894, the Buick tire was white and without any pattern.

But this white tire is not ideal for both tire strength and tearing resistance, and it is easy to age. And the price is also high. After a long time, the rubber will become yellow and brown, and the decorative effect is lost.

Later, when a company made a tire, it added a black material, carbon black, in addition to rubber. So the tire naturally turns black.

When carbon black is combined with rubber, it makes the rubber very strong. Although it has been technically capable of producing other colored tires, the manufacturing process is complex and costly.

After more than 200 years of back and forth experiments, people gradually accepted black, until now that black is still the rule of the tire industry.

What's the advantage of using black tires?

Functional advantage

Natural rubber has good elasticity, and rubber tyres can reduce the bumps in driving.

But the natural rubber has a natural disadvantage of abrasion, hot melt and grip, and it can be easily worn out without friction.

Black tires are safer

The high safety of the black tires is also an important reason for everyone to recognize it. Accidents caused by tire failure account for a large proportion of automobile accidents. Therefore, regulators pay more and more attention to tire wear resistance and anti-aging rate, and only black tyres can achieve good wear resistance and anti-aging.

In addition, the study found that the color tires are easy to make the opposite driver feel dazzling and dazzling, which can bring potential danger to pedestrians or drivers.

Black tires are high cost performance

According to the current manufacturing process, producing other colors of tyres is not difficult, but for cars, the manufacturers pay more attention to the overall performance and cost performance of tires. Manufacturers found that black tyres with carbon black material can really balance the performance and price of tires, while the other color tyres are difficult to achieve real balance in the manufacturing process and cost.

About 30% of the current tires are carbon black. Of course, with the development of the tire industry, there will be other materials to replace the original raw materials, and may also appear other colors.

Michelin has developed the world's first color tyre. Now a lot of manufacturers will not be vulnerable to wear, such as tyres on the tyres, some of the color to decorate.

Although the tires are black in the world at present. But when the color tires are widely used one day, the road will certainly be a colorful scene.
