4. Leave one tyre iron in position,
and pry the rest of the bead over the
rim with the other iron. Take small
"bites" with the iron around the tyre
in order to avoid damaging the seal·
ing surface of the tyre bead.
5. Stand the wheel and tire up-
right with the tyre outer bead in the
drop center wen at the hottom of the
wheel. Insert the tyre iron between
the bead and the edge of the wheel
rim. and pry the wheel out of the
tire.
INSTALLING TYRE ON WHEEL
1. If a used tire is being installed
remove all dirt from the tyre
If a tyre is being mounted to the
original wheel, clean the rim with
emery cloth or fine steel wool. Check
the rim for dents.
If a new wheel is being installed,
coat a new valve with lubricant and
position the valve to the new wheel.
Use a rubber hammer or a valve re-
placing tool to seat the valve firmly
against the inside of the rim.
2. Apply rubber lubricant to the
sealing surface on both tyre beads.
With the outer side of the wheel
down, pry two beads over the wheel
rim
with two tyre irons, or
by
u5ing
a rubber mallet.
3. Align the balance mark on the
tire with the valve on the wheel.
4. Hold the beads against the rim
ftangcs by positioning a tire mount·
ing band
over
the
tire
(Fig.
77).
If
2
mounting band is not available, tie
a torniquct of heavy cord around
the circumference of the
tire.
Tighten
the cord with a tire iron. Center the
tire on the wheel with a rubber
mallet.
5. Give the tire a few quick bursts
of air to seat the beads properly,
then inftatc the tire to 40 pounds
pressure. Check to sec that the bead
positioning rings (outer rings near
the side walls) arc evenly visible just
above the rim ftanges all the way
around the .tire. If the rings are not
even, deftate the tire completely and
inftate it again.
6. When the rings arc properly
positioned, deflate the tire to the
recommended pressure.
