Mounting tires
When mounting a tire make sure that no foreign mat-
ter such as dirt or sand gets inside the tire and that
you do not damage the inner tube in the process.
Slip one bead of the tire onto the rim. Using your
thumbs, press one bead over the edge of the rim and
then around the entire circumference. This should
normally be possible without using tools.
Stick the valve of the inner tube through the hole in
the rim
(a)
. Inflate the inner tube slightly so that it
becomes round and push it into the tire all the way
round. Make sure not to leave any folds in the inner
tube.
To finish mounting the tire, start at the opposite side
of the valve. Using your thumbs, press as much of
the second bead of the tire over the edge of the rim
as you can.
Make sure the inner tube does not get pinched and
squashed between the tire and the rim. You can pre-
vent this by pushing the inner tube into the hollow of
the tire with a finger as you work along
(b)
.
Work the tire into the rim by approaching the valve
symmetrically from both sides. Towards the end,
you will have to pull the tire vigorously downwards
(c)
to make the already mounted portion of the tire
slip towards the deepest part of the rim well. This will
ease the job noticeably on the last centimeters.
Before fitting the tire completely on the rim check
again whether the inner tube lies properly inside the
tire and press the last stretch of tire over the edge of
the rim using the balls of your thumbs.
If this does not work, you will have to use the tire
levers
(d)
. Make sure that the bent ends point
towards the inner tube and that the inner tube does
not get damaged.
Push the valve subsequently a little into the tire so
that the inner tube does not get caught between
the rim and the tire beads. Check whether the valve
stands upright. If not, dismount one bead again and
reposition the inner tube.
To make sure the inner tube does not get pinched
between the rim and the tire beads move it sideways
back and forth between the sides of the rim. While
doing so, also check whether the rim tape has shifted.
Inflate the tube to the desired pressure
(e)
. The max-
imum pressure is indicated on the side of the tire.
Check whether the tire is properly seated by inspect-
ing the fine witness line
(f)
on the tire
just above the
rim edge. This line should be even to the rim all around
the tire. If it is not, deflate the tire a little and check
again. Starting from the maximum tire pressure you
can now reduce the pressure through the valve to
suit your needs. Please observe the recommended
tire pressure range.
