Abstract
Apparatus for measuring the rolling resistance of tires. A load cell is mounted on a base and a support is slidably mounted on the base adjacent the road wheel. A tire is mounted on a spindle which is in turn rotatably mounted on bearings to the support. A mechanism is provided for urging the tire against the road wheel. The bearings consist of an inner bearing housing supported by a hydrostatic bearing in an outer housing. A load cell is connected between an inner bearing housing and the support to block rotation of the inner bearing housing and to measure the extraneous losses due to bearing resistance and the like.
