I find it very surprising that increasing width would decrease rolling resistance. I sure see the opposite effect on the only experiment I can conduct: road bike vs mountain bike. I run a fairly smooth road-type tread on the MB, and inflate them to their max pressure, yet it takes perceptibly more effort to maintain a given speed than with the skinny-tired road bike.
