for cars equipped with TPMS sensors.
Place the tire to be mounted on the rim. Swing the
mounting arm forward so that the mount/demount head
is in the working position. Engage the lower bead OVER
the mounting wing and UNDER the mounting ! nger of the
mounting tool. Turn the wheel clockwise and push the tire

help device.
A. Mount the !
rst bead.
Position the roller (Item 1) and the bead pusher tool (Item
2) as showed in Fig. 4.2-5.
B. Lower the bead pusher so that the roller and the bead
pusher tool on the tire help keeping the bead into the drop
center (Fig. 4.2-4).
The bead pusher tool follows the tire rotation during the
mounting operation.
Bring the roller and the bead pusher tool back to rest
position.
