Want To Know Why Tyres Are Always Black In Colour?…
Tyre manufacturing companies keep spending billions of dollars on research to improve on its efficiency. Michelin recently developed a tyre that keeps working without going flats. The tyre, which will be offered in all Chevrolet Bolt in 2024, is currently being tested.
We also have a new tyre breakthrough from Continental AG – the world’s fourth-largest tyre manufacturer. The tyres are designed to regulate its pressure on its own while in motion.
But have you ever wondered why the colour of tyres are always black, despite its main constituents, rubber, being white?
Or you probably thought the black colour was chosen over white mainly because, black can withstand more dirty than any other colour?
The first rubber car tyres, which were invented over a century ago, were in fact white in color. So why do we have black tyres and not white around today?

Reason Why Tyres Are Always Black In Colour:
Early white coloured tyres were very prone to wear and tear, which quickly leads to deformation and short lifespan. To address this issue, carbon black, an excellent heat conductor, was added to improve the properties of the vulcanised rubber.
The aim of adding the carbon black pigment is not to change the colour, but to improve the rubbers resistance to wear and also to increase its durability and lifespan.
Today, all tyre manufacturers use almost the same materials to make their tyres. These materials includes either synthetic or natural rubber, fabric and wire, along with carbon black and other chemical compounds.
Modern tyres, be it a run flat, off-road or all season type of tyre, consists of a tread and a body, which are gotten from the materials listed above. The tread provides traction, while the body provides containment for a quantity of compressed air.
