How To Repair A Flat Tyre
There comes a time when most cyclists will need to repair a flat
tyre. Use the following steps to guide you through the process:
1. Take the wheel off the bicycle.
2. Using the valve, entirely deflate the tyre.
3. Push the tyre bead inwards around the whole rim to loosen.
4. Using tyre levers only (to avoid damaging the rim), prise one
side of the tyre bead up over the edge of the rim.
5. Leave the tyre on the rim and remove the tube.
6. Replace or repair the tube. Note: The replacement tube size
needs to correspond with the size detailed on the sidewall
of the tyre and the valve type needs to be suitable for your
bicycle. Refer to the instructions in your tyre repair kit to
successfully patch a tube.
7. To determine the possible cause of the leak, match the
position of the puncture in the tube in relation to the tyre
and mark the location on the tyre.
8. Remove the tyre completely from the rim and examine,
removing any foreign objects noted, eg. glass or a nail. Also
inspect the inside of the rim for other potential causes, such
as protruding spokes. Replace the rim tape covering the
spoke ends, if damaged.
9. Remount the side of the tyre onto the rim.
10. Partially inflate the tube with a hand pump until it starts
to take shape.
11. Taking care not to twist the valve stem, place it through
the hole in the rim and work the tube into the tyre.
12. Starting either side of the valve use your hands to remount
the other side of the tyre by pushing the edge toward the
centre of the rim. Work around the rim until the tyre is almost
completely remounted.
13. Push the valve up into the rim and ensure that the tyre
sits properly in position.
14. Remount the remainder of the tyre by using your thumbs
to roll the last, most difficult, part on. Note: Do not use
tyre levers as these can easily puncture the tube
or damage the tyre.
15. Ensure that the tube is completely free of the rim
and the tyre bead at all points.
16. Inflate the tube with a hand pump until the tyre begins
to take shape, ensuring the tyre bead sits evenly around
the entire rim. Fully inflate the tyre to the pressure marked
on the sidewall when properly positioned. Check pressure
with a tyre air pressure gauge.
17. Replace the wheel into the frame and adjust gears, brakes
and quick release levers as necessary.
