4.0 MOUNTING AND DEMOUNTING PRECAUTIONS
IMPORTANT!
BEFORE MOUNTING A TIRE ON A RIM, PAY
ATTENTION TO THE FOLLOWING:
A. THE RIM MUST BE CLEAN AND IN GOOD
CONDITION: IF NECESSARY CLEAN IT AFTER
REMOVING ALL WHEEL-WEIGHTS INCLUDING ‘TAPE
WEIGHTS’ INSIDE THE RIM.
B. THE TIRE MUST BE CLEAN AND DRY, WITHOUT
ANY DAMAGE TO THE BEAD.
C. REPLACE THE RUBBER VALVE STEM WITH A NEW
ONE OR REPLACE THE ‘O’ RING IF THE VALVE STEM
IS MADE OF METAL.
D. IF THE TIRE REQUIRES A TUBE, MAKE SURE THE
TUBE IS DRY AND IN GOOD CONDITION.
E. LUBRICATION IS NECESSARY TO MOUNT THE TIRE
CORRECTLY AND GET A PROPER CENTERING. BE
SURE YOU ARE USING APPROVED LUBRICANT ONLY.
F. MAKE SURE THE TIRE IS THE CORRECT SIZE
FOR THE RIM.
4.1 DEMOUNTING TUBELESS TIRES
A. Remove all wheel-weights from the rim. Remove the
valve stem or valve stem core and defl ate the tire (Fig.
4.1-1).

B. Break both beads.
Hold open the Bead Breaker, roll the tire/rim into the
Breaker area (Fig. 4.1-2). Ensure that the tire/rim
assembly is fl at against the rubber breaker pads on the
side of the machine. Make certain that the bead breaker
blade is not over the top of any portion of the rim. Now
activate the bead breaker pedal. As soon as the bead
dislodges from the rim, release the breaker foot pedal. It
may be necessary to rotate the tire 90 degrees and repeat
the above procedure to dislodge all beads.
Pay extra attention during this operation as it is easy to
mistakenly keep your foot on the bead breaking pedal
too long. This could potentially result in bead or rim
damage (Fig. 4.1-2)

NOTICE !
ON VEHICLES WITH TPMS PRESSURE SENSORS
INSTALLED, BREAK THE BEAD AT 90 DEGREES
OFFSET FROM THE VALVE STEM. DAMAGE TO THE
WHEEL AND/OR SENSOR MAY RESULT IF THE BEAD
IS BROKEN AT ANY OTHER POINT ON THE RIM.
C. Set the rim clamps to the proper position: retract
clamps to clamp the wheel from the outside.
When clamping small wheels (14” or smaller) from the
outside, set the clamps at a diameter nearly equal to the
rim diameter before placing the wheel on the clamps.
This will help avoid the possibility of pinching the tire as
the clamps retract.
NOTICE !
TO MINIMIZE THE RISK OF SCRATCHING ALLOY OR
CLEAR COATED RIMS, THESE RIMS ARE CLAMPED
FROM THE OUTSIDE. USING OPTIONAL PLASTIC
RIM PROTECTION WILL MINIMIZE RIM DAMAGE
FROM THE OUTSIDE.
