Well, I happened to recently acquire a Continental GP4000S tire for a very reasonable price, and in light of the recent Flo aero testing, I decided it would be a good time to throw it on the rollers and see how it does. I also had a couple of well used "training/all condition" tires a friend loaned me so I tested those as well. Wow...some of those training tires REALLY sap the power!
Anyway, here's the predicted on-road Crr for the 3 tires I tested today:
Continental GP4000S 23C = .0034
Specialized All Condition Pro II 23C = .0062
Specialized All Condition Armadillo Reflect 25C = .0077
The overall Crr chart now looks like this:
And here is the predicted power for 2 tires at 40kph (85kg total load):
