The recesses 16 form a plurality of equally spaced, substantially planar, congruent surfaces 18 parallel to the longitudinal axis of the roller 12 and circumferentially positioned around the perimeter of the roller 12. The surfaces 18 engage the drive wheel of a vehicle and limit slippage and/or creepage between the drive wheel and the roller resulting in increased power transfer between the drive wheel and roller and increased dynamometer accuracy and repeatability. | |
