same time, pull the tire so that the tire “beads” (there are two) are
removed from the rim. If the bead is too tight for you to unseat with
your hands, which will likely be the case most of the time, use your
plastic tire levers to lift the bead carefully over the rim. It is not likely
you will be able to unseat both beads, so start with one by inserting
the lever under the bead and, while sliding the lever along the rim,
pull the bead out and over the rim. Continue sliding the lever around
the entire rim exposing the tube. Careful when approaching the valve
stem so as not to damage it when sliding the lever past it. Next, push
the valve stem out of the hole of the rim (remove the valve lock if it
has one) and remove from the inside of the tire. At this time, you still
have one tire bead remaining in the cradle of the rim. You can either
remove the tire completely off the rim by repeating the steps above
or simply leave the tire partially seated in the rim.
Now carefully inspect the outside and inside of the tire for the cause
of the puncture and remove the cause if it still there. If the tire is cut,
try using tape, a spare patch, a dollar bill or whatever you have handy
to line the inside of the tire to contain the re-installed tube when
inflated. This technique is a temporary repair so that you can return
home or get to your local dealer for a new tire.
WARNING:
If the tire is cut, you must replace with
a new tire as soon as possible to avoid the risk of injury
while riding your bicycle.
Now decide if you want to use a patch (follow instructions in your
patch kit) or simply replace the tube for a quicker repair. If you choose
the latter option, and depending on the damage to the tube, you may
be able to repair the tube when you return home and use it again.
WARNING:
Patching a tube is an emergency repair.
If you do not apply the patch correctly or apply several patches,
the tube can fail, resulting in possible tube failure, which could
cause you to loose control and fall. Replace a patched tube as
soon as possible.

NOTE:
If you prefer to evaluate the damage to the tube to
determine your course of action, begin with locating the hole in the
tube. You may not be able to easily see the hole so take your pump
and inflate the tube until you hear air escaping the tube. If you have
water available, you can also pour water on the tube after partially
inflating and watch for bubbles or a hissing sound. When the hole is
located, decide if you want to use a patch or replace the tube.
Now it is time to reinstall the tire and tube. If you have removed
the tire completely, start with pushing one tire bead inside the rim
and when completed, grab your tube and insert the valve stem
through the hole of the rim. Gently stuff the tube into the cavity of
the tire being very careful not to twist the tube. Now inflate the tire
just enough to give it some shape. Starting at the valve stem and
working around both sides of the rim to the side opposite the valve
stem, use your thumbs to push and seat the other bead of the tire
inside the rim. Be careful not to pinch the tube between the tire
