Most people think of tyres as black rubber but it’s not the rubber that makes them black – carbon black powder is the critical ingredient that not just gives the colour but also provides the structural strength that tyres need – both on the road and the race track. A tyre typically contains around 30% of carbon black which is one of the most critical ingredients in tyre construction. Simply, it is manufactured by burning crude oil and manufacturers around the world offer ever-improving qualities At the time of manufacturing of tyre large amount of sulphur is also added to provide good strength and rigidity to tyres so they can be used for long time even in greater friction place.black colour also absorbs more heat which can help the car to run better
hope this helps!

Its due to the carbon black powder that they put in during production of the rubber this helps stabilise the compound and reduce the damage caused by environment in which the tyre is used therefore extending its life.

Tyre is tire, and colour is color.
because if they paint the rubber, the prices of tires would go up. Ans then they might be out of the color you want. Can you imagene, Pink tires??
