I only know of some bike tires that are blue. But why isn’t it more common to find tires in different colors other than black?
In: Chemistry
The vast majority of tire rubber compounds use a soot-like material called “carbon black” as filler to add strength, rigidity, and durability while reducing cost.
This material is, as you might imagine, jet black.
The rubber itself is brown or white, depending on the source. Natural rubber is brown, synthetics are yellowish or bright white.
