Rolling Resistance
From WikiPedalia
The friction caused by the flexing of the tire and tube as it deforms under load, and of the wheel bearings. For a given tire, rolling resistance will vary considerably with the inflation pressure: the higher the pressure, the lower the rolling resistance. The rolling resistance of the tire and tube is typically far higher than that of the bearings.
