MOUNTING THE TIRE
When mounting tire with a tire changing ma-
chine, use care to avoid wrinkling, tearing or
cutting the flange of the safety shield. Motor
driven attachment should not be used.
When mounting with tire irons, work the
beads over the rim flange carefully in short
sections. Make sure the shield is properly
seated on the first bead before starting the
second bead over the rim flange. Should the
captive-air safety shield slip off either tire
bead while mounting, it can be repositioned
after the tire bead is in the rim well.

INFLATION
IMPORTANT
Insert the inflating needle into tire sidewall
valve full length (Figs. 11 and 12).
With valve core in the rim valve, apply air
pressure. If the beads do not contact the rim
bead ledge sufficiently to catch the pressure,
use a bead expanding device as used on tube-
less tires.
Inflate the safety shield through rim valve to
desired pressure. Inflate outer compartment
through sidewall inflating valve to desired
pressure. Inflating valve may tilt down toward
rim when the safety shield is inflated, in which
case air should be introduced with sidewall
valve in this tilted position.
Should additional pressure be required to
seat tire beads firmly against rim flanges, ap-
ply it to the outer compartment and then re-
lease to the desired operating pressure through
the needle valve in the tire sidewall.
Under this procedure, pressure in the inner
compartment will be 2 or 3 pounds above ori-
ginal inflation, which provides a reserve that
will filter slowly through the walls of the safe-
ty shield to replenish a slight pressure drop in
the outer compartment resulting from tire
growth during the first few days a new tire
is in service.
If tire beads do not seat against the rim
flange at 40 lbs. inflation pressure, deflate tire
and relubricate safety shield and readjust tire
for better centering to remove any binding
action that may have taken place.
CAUTION
BECAUSE OF THE DANGER OF BREAKING
TIRE BEADS, DO NOT USE MORE THAN
40 LBS. INFLATION PRESSURE FOR SEAT-
ING THE TIRE BEADS AGAINST THE RIM
FLANGES.
When safety shields are properly mounted
and locked on the rim, the mounting guides or
small rubber beads on the edges of the shields
will be visible and uniform around both sides
of the tire at the top edge of the rim flange.
If mounting guides are not visible around
both sides of the tire, deflate the tire and loosen
the beads from the rim to permit readjustment
of the safety shield.
