5.3 Mounting tires

Note: If mounting a tire starting from the bare rim,
clamp in place as described in section 5.1
Locking Rims.
Figure 5.3-1
• Lubricate the entire rim surface.
Figure 5.3-2
• Lubricate both beads of the tire, inside and outside,
with a tire lubricant.
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 THE TIRE AND OBTAIN
CORRECT ALIGNMENT ON THE RIM. BE SURE YOU
ARE USING AND APPROVED TIRE LUBRICANT ONLY.
• Rotate the rim until the valve is in the 5 o'clock
position.
IF THE VALVE HAS A PRESSURE SENSOR
(T.P.M.S.), PAY ATTENTION NOT TO KNOCK IT WITH
THE TOOL OR THE BEAD.
• Place the tire to be mounted on the rim.
• Set the tool to working position.
BEFORE BRINGING THE WORK ARM INTO THE
WORKING POSITION MAKE SURE THE MOUNT/
DEMOUNT TOOL IS NOT LOCKED IN A POSITION
SUCH AS TO KNOCK AGAINST THE EDGE OF THE
RIM.
For the mounting, use the "QUICK MOUNT" device
fi tted on the arm of the lower bead breaker disc.
Turn the device over as indicated in fi gure 5.3-3.
Figure 5.3-7
• Engage the lower bead ABOVE the fi tting tab of
approx. 2 cm.
• Turn the wheel clockwise and push the tire down into
the drop centre, opposite to the mount/demount head.
Note: With low profi le tires it is possible to use
the Bead Pusher and Bead Breaker Disc
devices as described in the sections below.
Figure 5.3-8
• To remove the "QUICK MOUNT" from the tire, hold
the upper bead on the Mounting Helper hook and lower
the lower bead disk until the device get out.
