Shimano SI-TIREB Operating instructions

Technical Service Instructions SI-TIREB
Installing and removing
tubeless tires
General Safety Information
• The air pressure should be within the range of 200-400kPa {29-58psi}.
• The tires should always be installed and removed by hand. Never use tools such
as tire levers, as they can damage the seal between the tires and the rims and
cause air to leak out from the tires.
• Do not tighten the valve nut too much, otherwise the valve seal may become
warped and air leaks may occur.
CAUTION
• Read these Technical Service Instructions carefully, and keep them in a safe place
for later reference.
Note
• If the tires are difficult to fit, use plan water or soapy water to help them slide
more easily.
• Parts are not guaranteed against natural wear or deterioration resulting from
normal use.
WARNING
Valve nut
1. Installing tubeless tire valves
}Install the valve so that it faces as
shown in the illustration.
When tightening the valve nut, check
that the valve does not turn together
with the valve nut.

2. Installing the tires
}Insert the bead on one side of the tire
as shown in the illustration.
Check that there are no foreign
particles in the tire bead, rim and valve
at this time.
}Insert the bead on the other side of the tire starting from the point opposite the air
valve.
Tire
Rim
Bead
Air valve
It will become more difficult to insert the
bead at the side of the air valve. In such
cases, lift up the bead by hand starting
from the opposite side of the tire, and work
your way around to the location of the air
valve.
Lastly, grip the tire with both
hands as shown in the
illustration and insert the tire
into the rim.
Inflate with air to lock the beads of the
tires into the rim as shown in the
illustration.
After this, deflate the tire and check that
the bead is locked into the rim.
Then re-inflate the tire to the standard air
pressure for use.
If the bead is not locked into the rim, the
bead is separating from the rim when the
tire is deflated.
(Max : 400kPa / 58psi)

3. Removing the tires
}To remove a tire, deflate the
tire and then push the bead
on one side of the tire into
the gorge of the rim as
shown in the illustration.
Note:
Be sure to only push in the bead on one side of the tire. If you push
the beads in on both sides, the tires will be difficult to remove. If you
push in the beads on both sides, inflate the tire once more to lock the
beads, and then remove the tire by starting the procedure from the
beginning again.
}Remove the bead on one side of the tire starting from the
point closest to the air valve, and then remove the bead on
the other side of the tire.
}Loosen the locking ring of the air valve and remove the air
valve.
}Insert the bead on one side of the tire as shown
in the illustration.
}Liberally moisten the outer edges of the rim and
the tire beads, and place the slightly-inflated
inner tube inside the tire so that it can slide
smoothly.
}Check that the air valve of the inner tube is appropriate for
use with the rim.
}Insert the bead on one side of the tire starting from the side
of the rim opposite the air valve. Be careful not to pinch the
tube at this time. If necessary, use soapy water.
}Inflate the inner tube until the tire locks into place.
}Contact your dealer for the specifications of inner tubes that
can be used.
