4.2 Mounting tubeless tires

A. Lubricate the entire rim surface (Fig. 4.2-1).
Lubricate both beads, inside and outside, (Fig. 4.2-2).
WARNING
LIBERAL LUBRICATION OF THE TIRE AND RIM
IS NECESSARY TO MOUNT TIRE CENTERING
CORRECTLY AND GET A PROPER ON THE
RIM. BE SURE YOU ARE USING APPROVED
4.2-2 LUBRICANT ONLY.
WARNING
OBSERVE THE ROTATION DIRECTION OF
THE TIRE, IF REQUIRED. SOME TIRES HAVE
A COLOR DOT THAT MUST BE KEPT ON THE
OUTSIDE OF THE WHEEL.
B. Lock the rim on the turntable and rotate it to have the
valve in 5 o'clock position. Place the tire to be mounted
on the rim. Swing the mounting arm forward so that the
mount/demount tool is in the working position. Engage
the lower bead OVER the mounting wing and UNDER
the mounting fi nger of the mounting tool. Turn the wheel
clockwise and push the tire down into the drop center,
opposite to the mount/demount head (Fig. 4.2-3).
C. Mount the upper bead following the directions in
section B (Fig. 4.2-4). With low profi le tires the pneumatic
bead holding and mounting tool "MH320 Pro" can help to
facilitate mounting of the top bead.
4.2.1 Use the bead presser as a mounting
help device.
A. Mount the fi rst bead.
Position the roller (Item 1) and the bead pusher tool (Item
2) as showed in Fig. 4.2.1-1.
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.
