A "rim" refers to the outer edge or border of an object, often circular in shape. It is commonly associated with items like wheels, glasses, and dishes. In the context of a wheel, the rim is the part that holds the tire in place and provides structural support. Rims can be made from various materials, including metal, plastic, or rubber, depending on their intended use. In sports, such as basketball, the rim is the circular metal hoop that players aim to score points by shooting a ball through. The design and size of a rim can vary significantly based on its application.
