An in-line skate wheel has a tire attached to a rim that mates to form a relatively rigid interlocking assembly with a wheel hub having concentric inner and outer hub rings interconnected nearly adjacent their outer edges by radially extending vanes. To enable rotation about an axis of rotation, a pair of bearings are co-axially retained by the wheel hub and mounted on a bearing sleeve located internal to the wheel hub.
