Tire Mounting
This information must be read and followed carefully
to prevent accidents and injuries during mounting.
WARNING
Check tire and wheel carefully before
mounting. Make sure the tire bead diameter
and wheel diameter match exactly. Con-
sult the Rubber Manufacturer’s Association
for approved rim widths for tire sizes. Mis-
matched tires and wheels explode.
CAUTION
Never Mount a tire and wheel handed to
you by anyone without checking both tire
and wheel for damage and compatibility. Be
extra cautious of persons without knowl-
edge of tire service. Keep by-standers out of
service area.
WARNING
Never mount a damaged tire. Never mount a
tire on a rusty or damaged wheel. Damaged
tires and/or wheels may explode.
CAUTION
If you damage the tire bead during mount-
ing, STOP!, remove the tire and mark it as
damaged. Do not mount a damaged tire.
1. Inspect the wheel closely for damage. Remove
any rubber or light corrosion from rim (figure 9). Inspect
both the inside and outside of the tire, and pay special
attention to the bead area. Do not attempt to service
heavily corroded wheels. Apply rubber lubricant to the
outside of both beads and to the inside of the top bead
(figure 10).
2. Place the tire over the wheel as shown in figure 11.
Hook the mounting end of the combination tool over the
rim flange and place the slot in the tool over the center
post key.
3. Grasp the tire and rotate it clockwise until the
lower bead contacts the mounting end of the tool.
Continue to rotate the tire until the bead slides into the
groove on the tool (figure 11).

your right hand to hold the combination tool down over
the center post key. Refer to figure 11.
5. Press the foot pedal. Continue to push the tire down
into the drop center and maintain pressure against the
combination tool while it rotates. Allow the combination
tool to make a full cycle.
