19.3 UHP (low profi le) and RUN-FLAT (self-supporting) tires mounting
- Some precise and careful operations are necessary to mount UHP and RUN-
FLAT tires. It is compulsory to follow tire regulations to avoid permanent damages
to these tires.
-Lower bead mounting can be performed as per standard instruction
at page 27 of this manual..
-Once the lower bead is mounted, keep the mounting arm and tool at working po-
sition and start WDK upper bead mounting procedure putting the tire slightly tilted
down to “3 o’clock” position.
-Use the bead pressing clamp together with the proper rubber protection
( steel rim, alloy rim, convex alloy rim) locking the clamp onto rim edge
with the valve at “3 o’clock” position.
If necessary, press the tire side by the upper bead loosening roller to
help the correct positioning and locking of the clamp (fi g. 1).
-Keep the upper bead loosening roller at drop-center level, spin slightly
to insert the pressing tool between the roller and the clamp and pressing
onto the tire side until the upper bead reaches drop-center level (fi g. 2).
-Make sure that the upper bead of the tire rests on the left lip of the mount head
and under the demounting claw on the right side of the head.
-Start spinning the wheel paying attention to the bead not going between
the rim edge and the bead loosening roller.
While spinning, when clamp is roughly at “6 o’clock” position make sure
that the whole bead within this section is right inside the drop-center.
-If this necessary condition for a correct mounting is not accomplished,
use the bead pressing unit pushing its tool onto the tire side to insert
the bead into the drop-center (fi g. 3).
- Go on spinning the wheel until the upper bead is completely mounted.
- Remove the clamp and the rubber protection by the help of the pressing unit.
Pull the pressing tool away and lift the roller away
from the working position by acting on button 10.
Press button 7 to move the bead loosener from working position.
- Press the pedal ref. 1 to push the mounting arm up and move the roller bead
breaking unit away from working position.
- Keep the wheel locked onto the center-plate during the infl ating operations.
Read the infl ating instructions at page 23 carefully.
- Once the tire infl ation is completed, unlock the wheel and bring it down
onto the fl oor, taking advantage of the optional wheel positioning unit.
