using small bites until bead slips
over flange onto rim base. If nec-
essary, insert second tire iron
and lubricate last 6" of bead be-
fore completing mounting (fig.
72).
4. Check valve to be certain
that hex nut at the valve base is
tight. Inflate tire to recommended
operating pressure.
Check as-
sembly for air leaks.
Mounting (6.70-15 tires)
1.
Use present tire machines or
standard tire irons following the same
procedure used in mounting tube type
tires, however, extreme care must be
exercised to prevent injury to the seal-
ing bead when forcing tire over the
rim. A light application of rubber
lubricating soap on the last
1f3
of each
bead circle to be mounted will ease
mounting.
2. With tire beads still unseated,
rotate tire on wheel so that balance
mark on tire lines up with the valve
stem.
3. Start tire beads into the rim bead seats as follows:
If a tire mounting machine is being used, lift the tire high
in the rim forcing the top tire bead against the top rim flange
seating the top bead. The lower bead will be seated by the
tire weight.
When a tire mounting machine is not being used beads
may be seated by holding the tire and wheel assembly in a
vertical position and bouncing on the floor at various points
about the tire circumference.
4. Install valve core and inflate tire with quick "shots" of
air to firmly seat the sealing beads.
5. Check assembly for air leaks, then reduce tire pressure
to that recommended for vehicle operation.
