How to Change a Flat Tire

Put the New Tube in Your Tire

Place the new tube in the tire.

Take the new tube and with it still flat, work it into the tire, laying it where it goes when it is inflated on the rim. Take care that the tube is not crimped or twisted at any point, and that the valve stem points to the center. Some people find that the tube is easier to work with if you put just a little bit of air in it, enough to hold it in the tire.
