4.1 Demounting Tubeless Tires

A. Remove all wheel-weights from the rim.
Remove the valve stem or core and defl ate the tire (Fig. 4.1-1).
NOTE: If the tire is over 13"(340 mm) wide, fi rst set the
bead breaker in the "Wide" position as follow:
1) Pull up and hold pin (1, Fig. 4.1-2), and pull the
bead breaker assembly in the "Wide" position.
2) Release pin (1, Fig. 4.1-2) in its hole to lock the
bead breaker in the new position.
3) To lock or unlock the blade rotation insert or
remove the pin (2, Fig. 4.1-2).
B. Break both beads.
Pay extra attention during this operation as it easy to
mistakenly keep your foot on the bead breaker pedal too long.
This could result in immediate bead damage (Fig. 4.1-3)
WARNING: ON CHEVROLET CORVETTE 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.
