Remove tire bead from the rim.
Pull tire back onto the rim.
6. Match the position of the leak in the tube with the tire to locate the possible
cause and mark the location on the tire.
7. Remove the tire completely and inspect for a nail, glass, etc. and remove if
located. Also inspect the inside of the rim to ensure there are no protruding
spokes, rust or other potential causes. Replace the rim tape which covers the
spoke ends, if damaged.
8. Remount one side of the tire onto the rim.
9. Using a hand pump, inflate the tube just enough to give it some shape.
10. Place the valve stem through the hole in the rim and work the tube into the
tire. Note: Do not let it twist.
11. Using your hands only, remount the other side of the tire by pushing the edge
toward the center of the rim. Start on either side of the valve and work around
the rim.
12. Before the tire is completely mounted, push the valve up into the rim to make
sure the tire can sit squarely in position.
13. Fit the rest of the tire, rolling the last, most difficult part on using your thumbs.
Note: Avoid using tire levers as these can easily puncture the tube or damage
the tire.
14. Check that the tube is not caught between the rim and the tire bead at any point.
15. Using a hand pump, inflate the tube until the tire begins to take shape, and check
that the tire bead is evenly seated all the way around the rim. When properly
seated, fully inflate the tire to the pressure marked on the sidewall. Use a tire air
pressure gauge to check.
16. Replace the wheel into the frame checking that all gears, brakes and quick
release levers are properly adjusted.
