Demounting tubeless tires
• Remove all wheel-weights from the rim. Remove
the valve stem or core and deflate the tire (Fig.
5.1-1).
• Break outer bead starting from opposite the valve
position. lubricate the bead and rim with a tire
lube only. Break inner bead. Do not hold the foot
pedal depressed longer than necessary since this
could damage the bead. Liberally lubricate bead
and rim (Fig. 5.1-2).
WARNING!
ON RUN FLAT WHEELS WITH THE OPTIONAL LOW
PRESSURE SENSOR INSTALLED, BREAK THE BEAD
AT 90 DEGREES OFFSET FROM THE VALVE STEM.
DAMAGE TO THE WHEEL WILL RESULT IF THE BEAD
IS BROKEN AT ANY OTHER POINT ON THE RIM.
5.1.1
Locking Rims
• Set the rim clamps to the proper position: retract
clamps to clamp the wheel from the inside and
expand clamps to clamp from the outside. When
clamping small wheels (14" or smaller) from the
outside, set the clamps at diameter nearly equal to
the rim diameter, before placing the wheel on the
clamps. This will avoid the risk of pinching the tire.
WARNING!
TO MINIMIZE THE RISK OF SCRATCHING ALLOY
RIMS, THESE SHOULD BE CLAMPED FROM THE
OUTSIDE.
• Liberally lubricate bead and rim.
• Place the wheel WITH DROP CENTER
UPWARDS (Fig. 5.1-3) on the turntable, and
clamp in position.
