How To: Once the tube is completely inside the tire, you can begin working the tire's other bead on to the rim. Start pushing the bead of the tire into the rim at the valve stem and then work your way around. Sometimes this is easy. But if your tire starts to get tight, you may need to resort to your tire levers again. Hopefully you won't need them and you'll be able to work the bead onto the rim. But if tire levers are a necessity, pay extra close attention that you are not trapping the tube under the rim when you use the lever to pry. It's easy to puncture a tube in this way.
