Abstract: A balancing device for a wheel and tire assembly has an elongate cylinder with an upper end, a lower end, an exterior surface and male threads formed on the exterior surface. A longitudinal cylinder bore extends axially through the cylinder and receives therethrough a suspension cord. The cord has a stop element at a support end extending beyond the lower end of the cylinder for supporting the cylinder. A support member has a wheel support flange and at least a first wheel hub centering section extending from the support flange. The centering section has a fixed diameter adapted to accommodate a particular diameter wheel hub opening of the wheel and tire assembly. An axial bore is formed through the support member and has female threads formed internally in the bore which correspond to the male threads of the cylinder.
