Everyone knows that tyres are typically black. Have you ever wondered why?
Although the natural colour of rubber is a milky white, the
black colour we see was originally caused by soot. The soot was thought to
increase the durability of the tyre along with cotton threads, which were inserted
in order to reduce heat and increase stability.
However, the main reason for black tyres on cars today, is the chemical
compound ‘carbon black’. It is used as a stabilising chemical, which is
combined with other polymers to create the tread compound of a tyre. Once added
to the rubber, carbon black increases the strength and durability of the tyres,
which is understandably seen as a desirable trait for tyre manufacturers and
car drivers.
