repair the inner tube
fig 41
Inspect the tyre, inside and out, for the cause of the puncture.
It may help to run your fingers around the inside of the tyre
but this should be done slowly and carefully as the object
that caused the puncture may still be sticking through the
tyre.
If there are any objects in the tyre remove them. If none are
found the puncture may have been caused by the tyre being
too soft and the inner tube becoming pinched between the
rim and a hard object.
Partly inflate the inner tube and listen carefully for airleaks.
Immersing the partly inflated tube in a bucket of water will
help locate small holes and valve leaks.
Once the hole has been located roughen an area of
approximately 2cm all around the hole using the grater or
sandpaper from the puncture repair kit.
