Automobile Engineering Interview Question:

WHY THE COLOR OF VEHICLE TYRES ARE ALWAYS BLACK IN COLOUR.
IS THERE ANY THING RELATED WITH HEAT CONDUCTION?

Submitted by: Administrator

During the process of vulcanisation of rubber to make it
sheer resistant to make tyres out of it, a certain
proportion of carbon is mixed into it. Without this
procedure the tyres will not be able to withstand the
friction n stress of the road. This carbon is responsible
for giving tyres the characteristic black colour.. 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
