Tire levers are simple tools used to help remove and install tires on bicycles. They are typically made of plastic or metal and have a flat, curved end that can easily slide under the tire bead. This allows users to lift the tire away from the rim, making it easier to change a flat tire or replace a worn-out tire. Using tire levers is straightforward. First, the user inserts the lever under the tire bead and pries it away from the rim. Multiple levers can be used in succession to fully detach the tire. Proper use of tire levers can prevent damage to the rim and make tire changes quicker and more efficient.
