Isn’t higher pressure faster?

Yes and no. In a laboratory environment, yes, higher pressure does create lower rolling resistance. However, we do not ride on perfect surfaces, and even the nicest, new pavement is imperfect. These imperfections in the surface exert an opposing force on the tire; a lower pressure tire is able to conform to these imperfections and keep momentum moving forward, and therefore roll faster.
