A wheel cover simulating a machined cast wheel is constructed by stamping a blank from sheet metal. Windows spaced angularly about the cover defined by radially inwardly angled borders simulating depth are formed on the blank. A marginal circular periphery is formed into a peripheral flange. The front face of the wheel cover is machined on a numerically controlled lathe, such that the cutting tool closely follows the contour, to form fine spiral grooves simulating machine markings generally concentric about the center of the wheel, thereby exhibiting a machined finish. A retainer ring is mounted interiorly within the flange and the flange rolled thereover to complete the assembly. This configuration provides a relatively inexpensive decorative wheel cover simulating a machined wheel.
