Hold lifting tool in place and depress the table
top control pedal momentarily to jog the wheel a
short distance. Check the wheel and tire to
verify that operation is not causing damage
(Figure 30).
Figure 31 - Jog wheel to remove Top Bead
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 and slip into drop center
on opposite side. Remove L.H. helper shoe
when about 1/4-1/2 bead is demounted.
Continue short rotations untill top bead is
completely demounted (Figure 31).

11. Demount lower bead. In most cases when
demounting performance tires, the lower bead
will be less difficult. Use helper dics to lift,
position, and hold tire. Pay close attention to
sensor/ transmitter location, make sure lower
bead is lifted above transmitter (Figure 32) and
position it directly below the demount tool when
starting the lower bead demount procedure
(Figure 32).
Performance Tires and Wheels - Mounting
1.
Lubricate both tire beads liberally. Performance
tires will require more lubrication than standard
passenger car tires.
2.
Mount the lower bead. In most cases, the lower
bead will mount easily.
Figure 33 - Mount Upper Bead, using Helpers
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 head. Use the
R.H. helper roller to help push and keep the top
bead in the drop center during mounting and use
L.H. helper shoe hooked over rim edge near the
roller to help hold the bead in the drop center
(Figures 33 and 34). The helper shoe will follow the
wheel while rotating the wheel in short steps and
apply extra lubricant to mount upper bead. Remove
the R.H. helper roller once bead is well started in
drop center.
Figure 34 - Mounting Top Bead
AF: Mounting the top bead can be very difficult when
mounting new tires on performance and custom
wheels. Proceed slowly and cautiously.
