Why Tyres are round in shape and Black in colour

 Reasons Why Your Car Tyres Have To Be Round......And Black In Colour.

At some point or the other in our lives we have surely heard this rhyme-"The wheels of the bus go round and round".In fact you may even have sung it at the top of your voice.But did you ever pause to think "why".I mean why should the wheels(and by extension tyres)be round?Why can't they be square rectangular or hexagonal in shape.

History has shown us that the simple why has been instrumental in revealing to us universal truths.For instance when an apple landed on his head sir issac newton did not give voice to the dark thoughts which must have obviously  crowded his mind.Neither did he simply make a nutritious afternoon snack of it. Instead he asked the pertinent question WHY.Why did apple fall down? And then he all of us found gravity.

This is but one example and i am pretty sure there are several when it comes to your car tyres,what are obvious whys that present themselves to you?Ican think of two- why are car tyres round and why are they black? so ask yourself these questions if you have not done so before.  And read on to find out the truths that will be revealed by the answers.

Truth #1: For Speed 

The tyres are the only  point in contact between yourr car and the road.The actually that tyres that get from point A to B. The round shape of tyres ensures that you are able to do this faster. Tyres moves by rolling. And the circular shape is the most appropriate one for this purpose as it maintains a uniform and smooth contact with the surface.

Any shape other than the round think square,rectangualr,hexagonal etchas edges or points that dig into the road.This makes movement slower.And with these shapes,rolling is definitely not an option.

Truth 2:To save you money OR For increasing Fuel Efficiency.

As your car tyres roll on the surface and take you to your destination they have to overcome frictional force offfered by the surface.This parameter called rolling resistance is directly related  to fuel efficiency.When the rolling resistance pushing up fuel consumption and the fuel efficiency plummets.Of all geometrical shapes the circles offers the least rolling resistance as it rolls realtively smoothly. 

Other shapes as we saw have points or edges that will dig into the surface and you obviously will need extra energy to undig so overcoming the resistance here will require more energy  meaning more fuel which pushes up the fuel consumption even more. In fact even with circular tyres manufactures are devising ways and means and innovative technologies to lower rolling resistance even further and produce highly fuel efficient green tyres that are environment friendly.

# TRUTH 3: For Greater Ride Comfort

Sure,you love the smooth ride your car gives.But do you know that this happens Because your tyres are round.The centre of a circle is equidistant from all points,so the mass of the car experience uniform movement giving you a smooth ride.With non circular tyres the mass of the car moves up and down as not all points equally situated from the centre and the tyre would have to compensate for that so hello back ache....... and uncomfortable rides.

Why are Your Car Tyres Black?

Carbon black is an essential strenghtening agent in your tyres which confers black colour absorbs more heat enhancing the tyre adhesion to the road and keeping you safe and sound on the ground.

But the Future Looks Colourful..................

Bridgestone tyres is developing a new colour tyre printing technology.Formula one tyres are also now colourful with pirelli p zero tyres.so sometime in the future,you could be looking at colourful tyres with custom printing. So now you are customising your cars....you may soon have customized tyres.

The era of black tyres may well be a thing of the past.....but era of round tyres is the future tooooo.
