What are wheels made out of?

OK ... If I understand this right, each wheel color is a different type of polystyrene and some types of polystyrene is faster than others. That explains why racers are using black and yellow wheels. The polystyrene in the red, orange and blue wheels must not prep as well as the black and yellow wheels making them slower.

Now to figure out what to do with the orange and red wheels I have.

This colored wheel thing is some buffoonery and hoodwinking. As a general rule, any wheel is as fast as any other wheel given the same attention to prep, regardless of color. There are certain molds that are preferred by some racers, but color is only aesthetics.

I ran some fast blue wheels. Orange is slow though!
