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. Clean the

wheel and remove any light corrosion or rubber residue

(Figure 12). Do not attempt to service heavily corroded

wheels.

Figure 12 - Inspect and Clean the Wheel

2. Inspect tire for damage, paying close attention to

the beads. Verify size match between tire and wheel

(Figure 12).

3. Lubricate tire beads liberally with tire manufacturer

approved lubricant (Figure 13).

Figure 13 - Lubricate Beads

4. Place tire over wheel and move swing arm into

position. Position the tire so that the lower bead is

above the rear extension of the mount/demount tool

and below the front knob (Figure 14).

Figure 14 - Position Tire Against Mount/Demount Tool

5. Depress table top pedal and rotate the wheel to

mount the lower bead. Use the drop center of the wheel

to reduce the tensional force on the bead by pressing

down on the tire directly across from the mount tool.

Rotate table top until lower bead is fully mounted.

6. For top bead, rotate the table top until the valve

stem is directly across from the mount tool. Lift the

upper bead up and over the rear of the mount tool.

With your left hand press down on the tire between the

mount tool and the valve stem to hold the tire in the

drop center. Depress the table top pedal and rotate the

tire until the bead is mounted. Continue to press down

on the tire during the remaining mounting process.

WARNING

Do not force the tire onto the rim. Bead dam-

age could result making the tire unsafe and/

or creating the risk of injury.

NOTE: If table top rotation stalls, reverse the table top

momentarily until the tire bead is again loose on the

wheel. Reposition the mount tool, make sure the bead

is correctly positioned in the drop center of the wheel,

then attempt mounting again.

NOTE: For low profile or stiff sidewall tires, it may be

advantageous to use the bead lifting tool to initially hold

the upper bead down in the drop center, or use drop

center tools as shown in Figure 30.

NOTE: For tube type tires, mount the lower bead first,

move swing arm out, install the tube, and then mount

the upper bead.
