Cd isn't a constant either, we just tend to treat is as such.

Nope, CRR goes up as speed goes up. I looked up a study on bias ply vs radial tires trying to see what kind off CRR differences there were. They concluded that the difference between a bias ply and radial tire is about the difference between a normal tire and a LRR tire. My baby V4 is stuck with bias ply tires thanks to current tire manufacturers' lack of tire choices, and its weird tire sizes. The study also says the larger tires have less rolling resistance, but there was no mention AT ALL about the actual width of the tire, just the rim size.(I think)
