ABSTRACT:
A dual rim assembly structure adapted to reduce cracking of gutter bands. An annular support wedge is disposed against an inclined surface to provide support under the lock-ring groove and reduce bending forces in the gutter band of each rim. A cylindrical spacer having annular tapered edges defines the support wedges. The spacer is disposed between the dual rim assemblies so that when the outer rim assembly is fixed to the hub, a lateral force is applied which forces the wedges of the spacer into engagement with the respective inclined surfaces of the gutter bands, thereby supporting both the inner and outer rim assemblies.
