Hi guys, well tires, and rubber? It is true that natural rubber is white. The problem is that white natural rubber is very easily damaged by sunlight. "Dry-Rotting" tires were everywhere!
It was somehow determined that the latex rubber would be more protected if colored, and red was used early on, and used in inner tubes for a long time after. The decision finally was to use black, and the earliest that I have heard of was by adding simple Lamp-Black to the raw rubber.
The mystery ingredient turns out to be simple, pure carbon.
