5.2 Mounting tubeless tyres

• Lubricate the entire rim surface. Lubricate both beads,
inside and outside, (Fig. 5.2-1).
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.
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
LUBRICANT ONLY.
• 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. 5.2-2).
• Mount the upper bead following the directions in
section B (Fig. 5.2-3). With low profi le tyres the bead
depressor tool "MX" (optional #EAA0247G70A) can
help to facilitate mounting of the top bead.
NOTE: FOR NARROW SIDEWALLS, RUN FLATS, OR
EXPECIALLY STIFF TIRES IT IS RECOMMENDED TO
USE THE MH 310 PRO ACCESSORY (Fig. 5.2-4).
A. Mount the first bead. After having positioned the
mounting/demounting tool, position the roller (ref. 1) and
the tool (ref. 2) as shown in Fig. 5.2-4.
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. 5.2-4).
Before distancing the mounting/demounting tool from the
tyre changer machine, set the roller and the tool pusher
in the rest position.
