Tire (US English) or tire (British English) is a kind of ring-shaped vehicle component, which covers the wheel rim to protect the wheel and make it have better vehicle performance. Most tyres, such as those used for cars and bicycles, provide not only traction between vehicles and roads, but also flexible cushion that can absorb impact.

Modern pneumatic tires are made of synthetic rubber, natural rubber, fabric and wire, as well as carbon black and other chemical compounds. They consist of tread and body. The tread provides traction and the body can hold a certain amount of compressed air. Prior to the development of rubber, the first version of the tire only had metal bands around the wooden wheels to prevent wear. Early rubber tires were solid (not pneumatic). Today, most tires are pneumatically inflatable, including rubber covered cords and steel wire doughnut bodies, usually filled with compressed air to form inflatable air cushions. Pneumatic tires are used in many types of vehicles, including cars, bicycles, motorcycles, buses, trucks, heavy equipment and aircraft. Metal tyres are still used in locomotives and railway vehicles, while solid rubber (or other polymer) tyres are still used in a variety of non automotive applications, such as some casters, trolleys, lawn mowers and trolleys.
