Performance Tires & Wheels • Mounting
Before beginning any of the mounting activities,
review all of the caution, warning and danger instruc-
tions associated with mounting already listed in the
early part of the manual concerning tire/rim size match,
inspect for damage, etc.
19.
Install or review condition of any pressure sen-
sor devices. This will prevent having to remount the tire
later.
20.
Begin the tire mounting process by lubricating
both tire beads and the rim if necessary (figure 38).
Figure 38 - Lubricate Tire Beads
21.
For mounting the lower bead; position the tire at
an angle to the rim and mount (figure 39).
Figure 39 - Mount the Lower Bead
22.
Next position the rim for the best mounting by
assuring the valve stem or sensor devices will not pre-
vent the upper bead from using the wheel’s full drop
center. Typically valves or sensor devices are posi-
tioned at 90 degrees forward of the duckhead.
3.
Position the valve stem 90 degrees clockwise in
front of the mount/demount tool for top bead mount-
ing. Lift the bead over the rear of the mounting head.
Use the helper tool to hold the bead in the drop center
(Figure 33). Rotate the wheel in short steps and apply
extra lubricant to mount upper bead.
Figure 33 - Mount Upper Bead, Use Helper
4.
On extremely tight tire and wheel combinations, it
may be necessary to use the bottom of the helper foot
to flip the tire bead over the rim flange (Figure 34)
