The present invention is an apparatus for a wear indicator system of an in-line skate wheel. The wheel includes a center hard plastic core hub, a first concentric portion (Resin B) of a color B, and finally a second concentric portion (Resin A) of color A. Resin A makes up the outermost portion of the wheel, thus undergoes wear first. As the portion A wears out portion B of color B, is exposed. When the outermost edge of the wheel displays only color B then the wheel has fully matured and should be replaced. The diameter of portion A and B should be determined based upon the resin hardness, the intended use and the shape of the wheel.
