5.4 Demounting tube-type tires

• To demount the tire operate as described for tubeless
tires in section 5.1.A through 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.
