2. Position wheel on tire machine with outside facing up.
Lubricate tire beads and mount inside tire bead on wheel.
Ensure "SIDE FACING OUTWARDS" lettering faces up
on GSA tires.
3. Install the right and left square nuts in the recesses of one
pair of runflat ends. When looking across the runflat to the
opposite side, the "R" square nut should be in the right
recess and the "L" square nut in the left recess
(Figure 6-25).
4. Start the cross bolt in one of the square nuts, then in the
second nut and tighten until there is full engagement in
both nuts. The thread engagement must be equal in both
nuts.
5. Using a bead spreader, insert the runflat halves in the tire.
6. Align the gap between the second pair of runflat ends with
one of the positioning fences on the wheel.
7. Assemble the second pair of runflat ends as in steps 3 and 4
and adjust the gap between the runflat ends to 53/64" (21
mm).

NOTE: The distance between the two runflat end gaps must
remain equal to reduce the risk of imbalance.
8. Verify that the positioning fences are centered in the
runflat end gaps and the gaps are equal.
9. Torque both cross bolts to 22 lb-ft (30 N•m) and install
cross bolt locking clips, screws and washers.
10. Torque the locking clip screws to 30-35 lb-in (4-5 N•m).
11. Lubricate tire bead and mount tire bead on the wheel.
NOTE: Before installing a new tire inspect tire sidewalls for a
"paint dot." Paint dots are often painted on tires to indicate the
tire's light spot for balancing purposes and may be located on
either side of the tire. If paint dot is present, position tire on
wheel so that paint dot is aligned with air valve on wheel. If
paint dot is not on air valve side of tire, reference paint dot
from other side of tire for proper positioning with air valve.
WARNING: Always use a tire inflation cage for infla-
tion purposes. Stand one side of cage during inflation,
never directly in front. Keep hands out of the cage dur-
ing inflation. Inflate assembly to recommended pres-
