The material from which the tires are made is actually milky white. It is made of synthetic rubber mixed with rubber tree sap. But the tires do not turn black as they look better.

Rubber tires were created in 1895. But the problem was that they were white. They became sticky and soft when heated and hardened again when cooled.

As a result, the tires darkened due to soot. Now this pigment is simply added to the manufacturing process. As a result, tires remain flexible and durable under load. In addition, carbon black protects tires from ultraviolet radiation, which makes the rubber brittle and destroys it.

Without the soot, the tires would wear out very quickly. Therefore, tires in various modes of transport are installed in black.
