Why are car tires always black.

The owner can choose any color for their car, but the tires will remain black. Given technological advancements, today's tires are black primarily because of carbon black, which is derived from oil.

The role of carbon black

According to research by a chemical engineer, the use of carbon black in rubber significantly extends the lifespan of tires. Carbon black strengthens the rubber, making it more durable and long-lasting. It also contributes to the smooth movement of tires, dissipates heat generated during vehicle motion, and protects the rubber from ultraviolet light and ozone.

Not always black

Previously, tires had a light color, but to strengthen the rubber, manufacturers added zinc oxide. However, further experimentation with various additives led to the use of carbon black to improve tire quality. After World War II, black became the standard color for tires.

New materials

Some manufacturers have started using silica as a substitute for carbon black in tire production. This material is more environmentally friendly and can bring new changes to vehicle tire manufacturing, providing better stability angle and reducing rolling resistance.

Overall, technological advancements in tire manufacturing help enhance the quality and durability of the products, ensuring safety on the road and comfort for drivers.
