Abstract
A skate wheel having a replaceable tread mechanically attachable to and mechanically detachable from a wheel hub. The wheel hub includes a central hub and a tread receiving ring around the hub outer radial periphery. A thread projecting from the tread receiving ring spirals around the outer radial periphery of the tread receiving ring. The replaceable tread includes a tread attaching ring and a ground engaging tread disposed around the circumference of the tread attaching ring. A mating thread projecting from the inner radial periphery of the tread attaching ring spirals around the inner radial periphery of the tread attaching ring. The replaceable tread and wheel hub are connected by the threaded engagement of the threads of the tread receiving ring and tread attaching ring. The present invention also includes a process for forming a high strength, low weight composite hub for the skate wheel.
