The prime reason behind keeping the tyre black is to improve the durability and robustness of the tyres
Everyone knows that the colour of a tyre is black but have you ever thought the reason behind it. Some of you might think that a tyre goes through mud all sorts of dirt-filled roads, so it is sensible to keep the tyres black. However, a tyre is not born black because when it was invented in 1895, it used to comes in white colour. The prime reason behind keeping the tyre black is to improve the durability and robustness of the tyres, as the compound used while adding carbon black to tyres works as a stabilizing compound.

The carbon black completely revamped the industry by making the tyres very durable, and that’s the reason why you see every tyre in black colour. Whenever we drive a car for a long period of time, the tread areas and belt tends to heat up, which can be very dangerous as it can cause tyre-burst. That’s where carbon black comes into play as it helps in maintaining the temperature of the tyres. In addition to that, carbon black also protects the tyre from the UV rays as the UV rays can harden the compound of the rubber, which in return will deteriorate the performance of the tyre.
Soot is also a reason behind the black colour, and it is created by burning an organic compound in an unfinished way. Soot is mainly used in a tyre to enhance durability. Nowadays, carbon black has replaced soot because it makes more sense. Even if black tyre appears to be boring for some people, it is very beneficial. It not only makes cleaning the tyres easier but also improves efficiency and durability. If compared to the white tyres, the black tyres make much more sense if we think about the practicality and safety aspects.
