5.0 Demounting tube-type tires
A.
For breaking the bead operate as described for the
tubeless tires in § 4.1.A to 4.1.F.
In this case, the valve is part of the tube.
WARNING
BE CAREFUL NOT TO DAMAGE THE TUBE DURING
THE BEAD-BREAKING OPERATION. THE VALVE
SHOULD BE OPPOSITE TO THE BLADE OF THE
BEAD BREAKER.
NOTE
: In order to avoid damage to their surface finish,
alloy rims should be clamped from the outside
only.
Special plastic caps are available as optional extras for
the clamping jaws so that alloy rims can be
clamped carefully.
B.
To demount the first bead, place the valve at 3 o’clock
position.
WARNING
DO NOT CATCH THE TUBE WITH THE BEAD LIFTING
TOOL, WHEN LIFTING THE BEAD ON THE
MOUNTING FINGER
After demounting the first bead remove the tube before
demounting the second bead, as described in section 4.1.
5.1 Mounting tube-type tires
A.
Proceed as described in section 4.2.A.
Do NOT lubricate the tube. Talc can be used to assist with
the tube positioning.
B.
Mount the valve core and place the tube onto the tire to
confirm that the tube is of the correct size (
Fig. 5.1-1
).
C.
Inflate the tube slightly: if held with the index finger it
should bend a little (
Fig. 5.1-2
).
D.
Mount the first bead as described in section 4.2.B.
Put the tube inside the tire and secure the valve with the
chuck of the inflating hose (
Fig. 5.1-3
).
Mount the top bead following the directions above.
5.2 Inflating tube-type tires
To inflate the tires unlock the rim and start inflating while
pressing the valve towards the inside. This is necessary
to avoid air pockets forming between tube and tire (Fig.
5.2-1).
Ensure that the tire is correctly centered on the rim and
complete inflation as described in section 4.3.
