Answer Posted / a.feroz khan
Most tire compounds are brownish color. In unprotected
forms, rubber compounds degrade as a result of ozone( part
of the air that we breathe). When ozone combines with
ultraviolet light from the sun, it attacks the tire polymer.
To prevent tires from rapidly deteriorating, a sacrificial
absorber is used, "carbon black" - which, fittingly, makes
tires black (carbon black is also used in inks, paints,
crayons, and polishes).
