Why don’t colored tires exist?
Interestingly, the color of tires became a hallmark of quality and durability. As people realized that black tires lasted longer and performed better, any other color became almost unthinkable for road use. The stabilizing chemical, carbon black makes the tires black. It prevents damage from UV light, draws heat away from parts of the car that tend to get hot when driving, and makes the tires durable.However, the white rubber did not offer sufficient endurance, so carbon black was added to the rubber to greatly increase tread life. Later, entirely black tires became available, the still extant white sidewalls being covered with a somewhat thin, black colored layer of rubber.
