Mounting tires
When mounting a tire make sure that no foreign matter
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 possi-
ble 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 sec-
ond 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 prevent
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 sym-
metrically 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 notice-
ably 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 be-
tween 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 maxi-
mum pressure is indicated on the side of the tire.
Check whether the tire is properly seated by inspecting
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.
