Operations
5.4 Demounting duplex and
supersingle tubeless truck tires
(over 13" wide)
FOR THIS OPERATION THE MOUNT/DEMOUNT TOOL
IS REQUIRED.
ONLY USE THE DEVICES INDICATED
1.
Break the bead of the tire as described in #5.2.1-5.2.6.
2.
For this type of tire it is not possible to demount both
beads at the same time as described in #5.2.7.
Engage the hook of the mount/demount tool between
the bead and the rim.
3.
Lift the chuck arm enough to clear the hook 2-3 cm
(1"-1"1/2) from the rim flange. Move the mount/demount
tool towards the outside. This will allow you to place
the long bar in between the bead and the rim flange for
necessary prying (Fig.5.4-1).

Rotate the chuck counter clockwise until the outer bead
is completely demounted (Fig.5.4-2).
5.

described in #5.2.7. (Fig.5.4-3).
