Abstract
A skate wheel (10) having a configuration of hubs (24), tire (14), spacers (26) and bearing assembly (22) which firmly locks the tire in place and yet allows the tire, bearing assembly and spacer to be replaced independently from the rest of the wheel when appropriate. In the preferred embodiment, each hub is formed with an annular recess to hold the spacer and bearing assembly. The tire is firmly locked into the present wheel by virtue of an annular tire flange (18) of rectangular transverse cross-section which is received into each hub and by acutely V-shaped projections (23) from each hub which are received into the tire. Small gaps are provided between hubs and spacers to prevent torsional overload of the bearing assembly. Peaks and valleys can be formed in mating hub and tire surfaces to prevent rotation of the tire relative to the hub.
