If the valve is working correctly and the tyre still goes flat,
then it has a puncture. To repair the puncture, you need to
remove the valve and the rim nut first (upend the bike to do
this). Press the edge of the tyre towards the centre of the
rim and push the first tyre lever between the tyre and the
rim. Take care not to pinch the inner tube while doing so to
prevent further punctures. Now insert the second tyre lever
right next to the first one and slide it over around a hand’s
width. Repeat this with the third one. Remove the second
tyre lever next (if it hasn’t fallen out of its own accord) and
insert it next to the third one. Repeat the procedure until
you have freed the tyre from the rim.
Now push the valve stem out and withdraw the inner tube
from the tyre. Refit the valve in the inner tube again and
inflate the tyre. If there is a large hole in the tube you will
hear the air escaping at once. You can locate a small leak
by holding the tube down in a bowl of water. Once you
have found the puncture, mark the spot with a pen and
then let all the air out of the tube and dry it off.
Clean the area around the hole thoroughly with a small
piece of emery cloth. Next apply a coating of solution
sparingly and allow it to dry for a few minutes (follow the
instructions with the solution). Cut out a patch to the right
size and stick it on the puncture. Apply firm pressure to
the patch and hold it down for a bit. Leave to dry for a
few minutes. Now check the tyre casing for sharp objects
(glass, nails and the like) and remove them to prevent any
further punctures. In order to verify whether the puncture
has been sealed you can inflate the tube again and draw it
through the water. If the puncture has been corrected refit
the tube over the rim. Feed the valve stem through the hole
in the rim first. Then fit the rest of the inner tube; ensure
that it is not folded over or twisted at any point. Inflate it
slightly as necessary. Ensure that the rim tape is correctly
centred as well, since it protects the inner tube from the
spokes.
Now fit the tyre working around the rim starting from the
valve by pressing it into the rim (this may require quite a lot
of force in the final section). Keep the valve stem pressed
in as far as possible, this will ensure that the inner tube
