Reminder of the function of the tire clamp: When disassembling and assembling a relatively hard tire, because the outer tire is relatively hard and has a relatively large rebound force, it will spring back to its original position after being pressed into the groove of the rim. The function of the tire clamp is to clamp a tire on the edge of the rim after pressing the tire to prevent the tire from rebounding. The tire clamp is only an auxiliary tool and cannot be used alone. attention please.
