vehicle tyres are black because carbon black is mixed in
them during manufacture which increases the strength of
tyres as well as make them resistant towards ultra violet
rays by converting uv radiations into heat.

Answer / hemant babu

according to black body concept,black body is a good conductor as well as radiator of heat.friction is there between tyre and road,so huge heat is generated which is to be radiated out, thats why it is made up of black colour.
heat may damage the a lot,so it is made black.

Answer / nishu reeves

Bcoz of the carbon mixed in the tyres...so it appears
black...why C is added?...to increase the puncture strength
nd the tread wear resistance of the tyre.

Answer / naseeb ahmeds

According to physics the black body is a well absober of
waves coming by the sun,in this UV also present which is a
reason to destroy the mechanical or electrical properties of
tyre material.so whatever the charges it is absorbing it can
transfer to earth......means the pressure of heat is not
going to effect the tyre.....

Answer / aditya tiwari

The automobile tyres are black in color due to following reasons :

1.)During the Vulcanization along with sulphur
is mixed into the rubber, this strengthens the molecular bond of the rubber and makes it more sturdy and durable, the reason of adding carbon black is because carbon black is available cheaper then any other material.

2.)Black color is good conductor of heat and can absorb the sunrays better, when a vehicle is out in open under the sun, the wear and tear will be very minimal as compared to any other color.

3.) During the run of the vehicle, the tyres tends to get hot and the specialty of the black color is that it does absorb heat fast and can return it back to the roads as well, so the temperature though hot but still remains balanced.

Answer / s.murugan

The black color of tires comes from carbon black, a readily-available material that provides greatly improved wear characteristics and heat-dissipation capabilities when added to rubber compounds.

Answer / ananth

we know already about black body radiation which absorps all
incident radiation.so we can use black color tyres

Answer / lavanya l

since, the black carbon is mixed with the materials added to manufacture tire. it looks black.In addition to that, black surface absorbs more radiations which may increase the strenth of the tires.

Answer / kulkarni ravindra

tyres are black in color because addition of carbon black in order decrease the puncture % and it gives good wear resistance and it helps to minimize the heat generated due to friction between tyre and road.

Answer / shiva goud

black colour absorb more heat rather then other but when we
are take any other colour so????
