A hubcap, wheel cover or wheel trim is a decorative disk on an automobile wheel that covers at least a central portion of the wheel, called the hub. An automobile hubcap is used to cover the wheel hub and the wheel fasteners to reduce the ac***ulation of dirt and moisture. It also has the practical function of decorating the car.[1] A "hubcap" is technically the small cover over the center of the wheel, while a "wheel cover" is a usually a decorative metal or plastic disk that snaps or bolts onto and covers the entire face of the wheel.[2] Cars with stamped steel wheels often use a full wheel cover that conceals the entire wheel. Cars with alloy wheels or styled steel wheels generally use smaller hubcaps, sometimes called center caps. Alternatively, wheel cover refers to an accessory covering an external rear-mounted spare tire (also known as a spare tire cover) found on some off-road vehicles.
