HOW TO FIX A FLAT TIRE
PUSH THE EDGE OF THE TIRE TOWARD
THE CENTRE OF THE RIM
REMOVE THE EDGE OF THE TIRE OF THE RIM
PUSH THE TIRE INTO THE RIM
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, axle nuts or quick release levers
are properly tightened.

If you need to repair a tire, follow these steps:
1. Remove the wheel from the bicycle.
2. Deflate the tire completely via the valve. Loosen the tire bead by
pushing it inward all the way around.
3. Press one side of the tire bead up over the edge of the rim.
Use tire levers, not a screwdriver, otherwise you may damage the rim.
4. Remove the tube, leaving one tire bead on the rim.
5. Locate the leaks and patch using a tube repair kit, carefully following
the repair kit instructions, or replace the tube.
Ensure that the replacement tube size matches the size stated on the
tire sidewall and that the valve is the correct type for your bicycle.
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 re-
move 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.
