High pressure skinny tires are fastest on a smooth velodrome. Low pressure mtn bike tires are fastest on the roughest pave of Paris-Roubaix. And it's a continuum in between. The testing mentioned doesn't isolate the tire as the wheel is loaded with a fixed load and rolled over a non-smooth surface.
