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.
