A wheel clamping assembly provides a frame having three arms, two fixed stops and a turnable cam. The arms are equally spaced and have holes to admit the stops and the cam. The stops have an extension eccentrically located upon the top of the cylinder. Then the cam has an involute, having an expanding radius, upon the top of the cam. In use, the stops are placed upon two arms and the cam is placed upon the remaining arm, all at the same radius. A wheel rim is positioned upon the stops and the cam. The cam is then turned to grasp the wheel. The stops and the cam are made of a non-marring material.
