Tires (fig. 63)
Start pressing the underside of the tire over the edge of the rim behind the valve.
Pump up the tube with a small amount of air until it is round; then insert it in the tire.
Check the tube for folds. If folds are present, release some air. You can now mount the rest of the tire starting
with the part 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 that 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 dust cap.
