This is not correct. Optimum speed comes are optimum pressure, which is usually quite a bit lower than most cyclists imagine. Going too high results in worse rolling resistance, AND worse handling AND worse comfort.
As a ballpack figure for a road bike, a 25c tire will usually have optimum rolling resistance at around 90-100psi for typical male rider mass and road surfaces.
And the faster, better handling tires also have less rolling resistance, but less durability.
