5.4 Demounting Duplex and Supersingle
Tubeless Truck Tires (Over 13” Wide)
Note: For this operation the mount/demount tool is
required.
1. Loosen 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 with the roller 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 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.29).

4. Rotate the chuck counterclockwise until the outer
bead is completely demounted (fig.30).
