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 position it
directly below the demount tool when starting
the lower bead demount procedure.

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 29 - Mount Lower Bead, Use Lifting Tool
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 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.
Figure 30 - Mount Top Bead
4. Mount the top bead using short rotations of the
wheel. As the wheel progresses, a second drop
center tool should be added to keep the bead in
the drop center.
Figure 31 - Add Second Drop Center Tool
5. On extremely tight tire and wheel combinations,
it may be necessary to use the hooked end of
the bead lifting tool to flip the tire over the rim
flange (Figure 32).
