TYRES: What are your tyres made of?
Modern pneumatic tyres are made from synthetic rubber, natural rubber, fabric and wire, along with carbon black and other chemical compounds.
They consist of a tread and a body. The tread provides traction on the road while the body provides containment for the quantity of compressed air needed to inflate the tyre correctly.
