A wheel for an in-line skate includes a hub composed of two halves. Each half has a centrally defined axle hole, a hollow cylinder formed on a periphery defining the axle hole, multiple rods formed on the inner side face, multiple indents defined in the inner side face and alternate relative to the rods, multiple segmented protrusions formed on a face of the skirt, multiple cutouts defined in the face of the skirt and alternate relative to the segmented protrusions and slits defined in the face of the skirt and a tire securely mounted on an outer periphery of the hub. Thus the rods from one half are inserted into the indents of the other half and the segmented protrusions from one half are inserted into the cutouts of the other half and the assembly of the wheel is accomplished.
