A wheel for an in-line roller skate of the type having aligned wheels, wherein a hub has an axial hole within which there are receptacles for ball bearings and a supporting pivot. One or two rings concentric with the hole form a support for a moldable tire which is molded onto the hub. The outer concentric ring has a plurality of thin annular sections and transverse openings to define an annular space between each of the annular sections and the ring connected by the transversal openings. The annular spaces and the transverse openings are filled with the material forming the tire to secure the same to the hub.
