Wheels

Wheels come in many different designs and usually fall into two categories: stamped sheet metal and machine castings. Some wheels are a combination of the two. Usually cast alloy wheels are higher priced, but have greater strength than stamped sheet metal wheels. Stamped sheet metal wheels are the most common, because they are less expensive to produce and are adequate for most uses. Some cars have wire wheels which consist of three basic components; inner rings, outer rings, and a series of spokes which connect the two. Cast aluminum wheels are very popular, magnesium wheels are also popular. Both are popular because they are light-weight and strong.
