13 Changing Tires

We recommend that you always carry an air pump and tire repair kit for emergency situations. As an alternative,
consider keeping a spray can of hardening foam (available at bicycle shops) to fill your tire in case of punctures.
• If a tire becomes flat, use the appropriate tools to carefully remove the tire from the rim.
• Be sure not to damage the rim and/or the inner tube.
• Repair the inner tube according to the directions in the repair kit, or replace the old inner tube with a new one.
• Before re-mounting the tire, inspect the inner rim surface and the inside of the tire for any object that may have
caused the flat.
• Ensure the rim bands are not damaged, as they protect the inner tube from being damaged by the ends of the
spokes.
Mounting (Fig. 54)
• Place the protective rim band over the valve and then push the valve through the rim. Screw on the valve nut if
there is one. The rim band can now be easily applied.
• Be sure all spoke ends are covered.
Tires (Fig. 55)
• Start pressing the underside of the tire over the edge of the rim behind the valve. Pump the tube with a small
amount of air until it is round; then insert it in the tire.
• Check the inner tube for folds. If folds are present, release some air. You can now mount the rest of the tire
starting with the section of tire opposite the valve by gently pressing the tire toward the valve.
Inflating
• Check around the tire on both sides to see whether the tube is clamped between the edge of the tire and the
rim. Push the valve back slightly and pull it out again so the tire is well-seated in the valve area.
• Fill the tire with enough air so that it can be pressed in easily with your thumb. Be sure the tire is centered on
the rim before continuing. If not, let some air out and realign the tire. Inflate the tire to the pressure indicated on
the side wall, and tighten the dust cap.
