top control pedal momentarily to jog the wheel a short
distance.

10. The lifting tool can usually be removed after
jogging the wheel a short distance. Continue to jog
the wheel to allow tire to flex where it crosses the
rim edge. Continue short rotations until top bead is
completely demounted.

11. Demount lower bead. In most cases when
demounting performance tires, the lower bead will be
less difficult. Use help to lift, position, and hold tire. Pay
close attention to sensor/transmitter location, and posi-
tion it directly below the demount tool when starting
the lower bead demount procedure.

1. Lubricate both tire beads liberally. Performance
tires will require more lubrication than standard pas-
senger car tires.
2. Mount the lower bead. In most cases, the lower
bead will mount easily.

3. Position the valve stem directly across from the
mount/demount tool for top bead mounting. Lift the top
bead over the rear of the mount tool. Use the lifting tool
to help push and keep the top bead in the drop center
during mounting, or use an optional drop center tool to
help hold the bead in the drop center (Figure 29 & 30).
Rotate the wheel in short steps to mount lower bead.
NOTE: Mounting the top bead can be very difficult
when mounting new tires on many performance and
custom wheels.
