Wheel types refer to the various designs and materials used in the construction of wheels for vehicles and machinery. Common types include steel wheels, known for their durability, and alloy wheels, which are lighter and often used for performance vehicles. Additionally, rubber tires are essential for providing traction and cushioning on the road. Different wheel types also serve specific purposes. For instance, spoked wheels are often found on bicycles, offering a balance of strength and weight. In contrast, solid wheels are used in industrial applications for heavy loads, providing stability and support without the risk of punctures.
