A wind-utilization attachment for pneumatic-tired vehicle for automobiles, aircraft wheels, or the like. The attachment consists of an annular disc with spaced cups to catch head winds and convert their forces into rotational torque. The disc is secured to a wheel by opposing arcuate clamping segments having flanges engaged between the tire side wall and the wheel rim, the adjacent ends of the clamping segments being bolted together. A removable cover cap is engaged in the central aperture of the disc, which when removed, provides access to the securing fasteners of the associated wheels.
