Abstract
Apparatus for measuring the rolling resistance of tires. An endless belt is supported on rotating drums. The upper run of the belt passes over a hydrostatic bearing which supports the belt against the force of the tire pressing against it. The hydrostatic bearing is formed by a plurality of nozzles directing water at high pressure against the underside of the belt. A pressure differential is created between the upper and lower surfaces of the belt to press the belt closely adjacent the nozzles so that when a tire is pressed against the belt, it does not create a depression in the belt.
