Reason why car tyres are black and cannot be any other colour

The black colour of car tyres is not just for appearance. It is mainly due to scientific and practical reasons linked to performance, durability, and safety. Tyres are made to meet strict standards, and their black colour plays an important role in meeting those requirements.

The role of carbon black

Tyres are black because manufacturers add a substance called carbon black during production. Carbon black is a fine black powder produced from partially burned hydrocarbons and is mixed with rubber to improve its quality.

This material increases the strength and durability of tyres, making them more resistant to wear and tear. Tyres are constantly exposed to friction, heat, and pressure, and without carbon black, they would wear out much faster. Carbon black also helps tyres release heat generated during driving, preventing overheating and improving overall performance and lifespan.

Protection from sunlight and oxidation

Carbon black also protects tyres from ultraviolet radiation and oxidation. Sunlight can damage rubber over time, making it hard and prone to cracking. Oxygen exposure can also weaken rubber compounds. Carbon black reduces these effects, helping tyres stay flexible and reliable in different conditions.

Why tyres are not other colours

Although tyres could be made in other colours, this would require pigments that do not offer the same strength and protection as carbon black. Coloured tyres would be less durable, more costly to produce, and more easily damaged by environmental factors. Black tyres also hide dirt and scuff marks better, making them more practical for daily use.

In summary, tyres are black because carbon black improves their strength, durability, heat resistance, and protection from environmental damage. The black colour reflects the industry’s focus on safety, practicality, and cost efficiency…CONTINUE MORE READING>>>
