Don't forget pressures. Yep, the GP4000 SII has 12.2 watts of rolling resistance according to bicyclerollingresistance.com.

At 8.3 bar...

35c Voyagers at 4.0 bar: 17.7 Watts

25c GP4000 SII at 4.1 bar: 15.5 Watts

And this is in a "lab" situation. Real world roads with real potholes, that's another story.
