A tire lever, also known as a tire iron or tire spoon, is a tool used for removing and installing tires on rims. It is commonly used in automotive maintenance, particularly for bicycles, motorcycles, and cars. The primary purpose of a tire lever is to pry the tire away from the rim, making it easier to remove or install. This is especially useful when dealing with tight or stubborn tires. Tire levers typically have a flat, spoon-like end that can be inserted between the tire and the rim, providing leverage to lift the tire over the edge of the rim.
