Do you know why the tires are black once white

At first, the tires were lighter or even white because the natural tire is a pale color, milk.

When automobiles first began production at the beginning of the 20th century, manufacturers used natural tires to make tires, resulting in a white or open - color view. To strengthen them, they added Zink oxid, which made tires even brighter.

With the growth of car speed and change of road conditions, however, the need for more stable tires became evident.

During 1910, manufacturers discovered that the growth of black carbon in rubber greatly improved its resistance and performance to consumption by strengthening the structure of the tire and protecting it from UV radiation and heat. The carbon black also makes the tire more resistant to cracks and prolongs its life span.

By the 1920 ' s, black carbon use became standard in the production of tires, turning tires into black and giving them their unique appearance today.

Not only did this change improve the practical aspects of tires but it also had the increased benefit of making them easier to clean and maintain compared with white or light tires.
