The car tires are black because soot is added to the tires during production to make them more durable. The tires themselves are largely made of rubber. However, despite the extensive chemical and thermal treatment, this soft ingredient does not have the right consistency for the tough everyday use on the road. The added soot ultimately ensures that the tire retains its shape for years, in addition to its desired elasticity due to the rubber, so that the driving characteristics are guaranteed over a correspondingly long period of time.
Since when are tires black?
Incidentally, historically car tires were not always black, but white or gray, especially in the early days of automobiles. At that time they consisted of a flexible rubber compound, but no soot had been added to it. As this happened more and more, the tires switched to the black warehouse, where they are in good hands to this day.
