Dismount A Bike Tyre

Introduction

A bike tyre unmounts by getting the tyre bead off its seat and down into the 'well' of the rim, the part of the rim nearest the centre of the wheel.

Step 3

<h3>Step 3</h3><p>Tyre levers have two hooks. Across one end is a hook to go under the bike tyre bead. Near the other end is a notch to hook onto a spoke. Metal levers last for ever but may damage fancy rims if used carelessly. Plastic levers tend to break, keep your hands over them when levering so that if they do break nothing will fly off and hit you in the eye.
