I suggest you add a note that the RR part is only true below 50 mph and explain what happens to RR at higher speeds.
I am aware of substantial deviations from the F=AVē+C model, and that F=AVē+BV+C gives a better curve fit. Is that all in the tires?

Can you give me an alternative to CRR model?

btw, here's Google Image Search for "pacejka rolling resistance":

If the first data point had been plotted at 0.0001 mph instead of 0, it would probably match the rest of the curve.
