What contribution did the Crayola make to your car's tires?

Binney & Smith, the maker of Crayola products, started out in the late 1800s making the color pigment for the paint used on the common red barns in rural America. Binney & Smith's carbon black was used by the Goodrich tire company to make automobile tires black and more durable. Originally, tires were white, the natural color of rubber.
