The tires of a school bus are made from a mixture of natural or synthetic rubber, carbon black, sulfur, and other chemicals, which determine the characteristics of the tires. Natural rubber is obtained from latex, a liquid produced when the bark of a rubber tree is cut. Synthetic rubber is produced from chemicals obtained from petroleum. Carbon black is made by burning petroleum or natural gas in a limited supply of air, resulting in a large amount of fine soot.

Well, I'm not sure they have to have black wheels. It is most likely a standard that everyone has followed. Blue Bird makes the majority of the school busses sold in the US and don't list any other color options. The school I went to had red white and blue busses and the wheels were all different colors. But it was a small private school so....who knows.

They want to make a fashion statement. Actually, the wheels are made by other companies like Budd, Kelsey-Hayes etc. On working trucks, busses, etc, black or white is the standard color. If the outfit building the vehicle wants it a certain color, it's up to them to paint them.

Because they are cheaper. You want school busses with chrome spinner wheels?

Least costly to maintain, rust does not show well, can be left dirty all of the time, etc..
