5.4 Demounting tube-type tires

· To demount the tire operate as described for
tubeless tires in section 5.1.
In this case the valve cannot be replaced because it
is part of the tube.
BE CAREFUL NOT TO DAMAGE THE TUBE
DURING THE BEAD-BREAKING OPERATION.
THE VALVE SHOULD BE OPPOSITE TO THE
BLADE OF THE BEAD BREAKER.
· To demount the fi rst bead, place the valve at 3
o'clock position.
DO NOT CATCH THE TUBE WITH THE BEAD
LIFTING TOOL, WHEN LIFTING THE BEAD ON
THE MOUNTING FINGER.
After demounting the fi rst bead remove the tube before
demounting the second bead, as described in section 5.1.

5.5 Mounting tube-type tires

· Proceed as described in section 5.2. Do NOT
lubricate the tube. Talc can be used to assist with
the tube positioning.
· Mount the valve core and place the tube onto the
tire to confi rm that the tube is of the correct size
(Fig. 5.5-1).
· Infl ate the tube slightly: if held with the index fi nger
it should bend a little (Fig. 5.5-2).
· Mount the fi rst bead as described in section 5.2. Put
the tube inside the tire and secure the valve with
the chuck of the infl ating hose (Fig. 5.5-3). Mount
the top bead following the directions above.
5.6 Infl ating tube-type tires
To infl ate the tire unlock the rim and start infl ating
while pressing the valve towards the inside. This is
necessary to avoid air pockets forming between tube
and tire (Fig. 5.6-1).
Ensure that the tire is correctly centered on the rim.
STOP THE COMPRESSED AIR AS SOON AS THE
BEADS GRIP THE RIM WELL.
· Place the wheel in a type approved cage to fi nish
infl ating and completely settle the beads in their
seats on the rim.
