The hp loss is related to the increase in centrifugal force of the 20" wheels. The greater diameter of the wheel the further the weight of that wheel is away from it's center, requiring more force to spin or stop that object. In essence, a heavy 18" wheel would be easier to spin than a lighter 21" wheel. You dig?
