Black Tires
Why Most Tyres Black Not Any Other Colour?
Benefits Of Black Tyres
While the very first tyres were created from bands of the iron placed on wooden wheels of carts and wagons, the first rubber car tyres which were invented in 1895, were in fact, white.
So why
are these white tyres not around today?
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.
Natural
rubber is off-white in color, and in fact the first rubber tires were
white.
Pure
vulcanized rubber is soft and wears out very quickly, however, and tends to
heat up and deform under load.
So you
want to mix something in with the rubber that adds temperature stability and
hardness — originally this was typically zinc oxide which made the tires bright
white in color.
However,
the main reason for black tyres on cars today is the chemical compound ‘carbon
black.’
It is
used as a stabilizing 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.
One way
carbon black expands the lifespan of tyres is by conducting heat away
from parts of the tyre that tend to get particularly hot when driving, such as
the tread and belt areas.
Carbon maintains
the quality of tyres by protecting them from UV light and ozone, which are
known to deteriorate tyres.
The above
are specialty tires from Double Star Tyre, a Chinese manufacturer, and are
mostly intended for show use (these likely use standard plastic pigments along
with silica filler — similar compounds are used for sneaker soles — this
provides good traction but much poorer wear characteristics than carbon black).
A
somewhat more mainstream variant is the Scorcher tuner-car tire from BF
Goodrich, which has embedded colored bands:
So it’s
possible to make useful tires with pigmentation other than carbon black.
However,
no other readily-available filler has been found with the combination of
beneficial properties seen in carbon black.
Other
Benefits Of Black Tyres
Not only
do the black tyres increase strength and durability, they also largely affect
the safety of your driving.
Having
stronger, long-lasting tyres means you will have a more reliable drive.
Tyres
could be considered the most important part of your vehicle as they affect
almost every performance factor from handling and acceleration to braking
and ride comfort.
It,
therefore, comes as no surprise that black tyres are the most popular
manufactured today.
When it
comes to looks, although black may be considered boring, they are definitely
easier to clean.
They are
therefore more practical than the white wall tires or fully white tires which
are sometimes seen to be more luxurious, particularly on classic cars.
While
some novelty cars with colorful tyres might exist, they aren’t considered
suitable for daily driving.
The plain
black tyres, though they may seem dull, are chosen for a very important reason;
tyre durability and road safety.
The black
colour is a good absorber of heat and can absorb the sun rays better when a
vehicle is out in open under the sun, the wear and tear will be very minimal as
compared to any other colour.
During
the run of the vehicle, the tyres tend to get hot and the speciality of the
black colour 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.
There are
also practical considerations; colored tires would be harder to keep clean and
might tend to clash with the color and style of the car itself — even if
multiple colors were made and stocked (itself a logistical challenge that would
increase prices) there would be many color shade combinations that clashed,
while “black goes with everything.”
