How To Fix a Flat Tyre

If you need to repair a tyre follow these steps:
1 . Remove the wheel from the bicycle.
2 . Deflate the tyre completely via the valve.
3 . Loosen the tyre bead by pushing it inwards all the way round the rim.
4 . Prise one side of the tyre bead up over the edge of the rim.
Note: Use tyre levers, not a screwdriver, otherwise you may damage the rim.
5 . Remove the tube, leaving the tyre on the rim.
6 . Locate the leaks and patch using a tube repair kit, carefully following the instructions, or replace the tube.
Note: Ensure the replacement tube size matches the size stated on the tyre sidewall and the valve is
the correct type for your bicycle.
7 . Match the position of the leak in the tube with the tyre to locate the possible cause and mark the
location on the tyre.
8 . Remove the tyre completely and inspect for a nail, glass etc. and remove if located.
Also inspect the inside of the rim to ensure there are no projecting spokes, rust or other potential causes.
Replace the rim tape, which covers the spoke ends, if damaged.
9 . Remount one side of the tyre onto the rim.
10 . Using a hand pump, inflate the tube just enough to give it some shape.
11 . Place the valve stem through the hole in the rim and work the tube into the tyre. Note: Do not let it twist.
12 . Using your hands only, remount the other side of the tyre by pushing the edge toward the centre of
the rim. Start either side of the valve and work around the rim.
13 . Before the tyre is completely mounted push the valve up into the rim to make sure the tyre can sit
squarely in position.
14 . Fit the rest of the tyre, rolling the last, most difficult, part on using your thumbs.
Note: Avoid using tyre levers as these can easily puncture the tube or damage the tyre.
