I just wanted to make sure that this is what makes riding a mountainbike with wide tires more exhausting. And obviously it is.
This also depends on tire pressure, and the thickness of the tread. If you could get wide tires to handle 120 or so psi pressure, and if the tread depth was very thin, similar to a road bike tire, then the main issue would be weight and not rolling resistance, since the amount of deformation of the tire would be less.
