A tire lever is a simple tool used to remove and install tires on bicycles and other vehicles. It typically has a flat, elongated shape that allows it to easily pry the tire away from the rim. Tire levers are usually made of plastic or metal and are designed to withstand the force needed to break the tire bead from the rim. Using tire levers is essential for anyone who performs their own bike maintenance or repairs. They help prevent damage to the tire and rim during the process. Proper use of tire levers can make changing a flat tire much easier and quicker, ensuring a smooth ride on your bicycle.
