NOTE: Some wheels have a low pressure sensor/

transmitter strapped to the wheel. This is especially

true on run-flat tire/wheel systems. The sensor is posi-

tioned directly opposite from the valve stem. To avoid

damaging the sensor, always loosen the top bead at

the valve stem first, then loosen the bottom bead at the

valve stem, and then continue to loosen the remaining

circumference of the beads as necessary (Figure 20).

3. Loosen bottom bead, starting with valve stem posi-

tioned directly next to the loosener shoe (Figure 21).

4. Liberally lubricate the bottom bead of the tire

(Figure 22).

5. Clamp the wheel to the table top as described in

item B, page 12. Always clamp custom wheels from

the outside.

6. Lubricate upper bead liberally. Use the bead lifting

tool to help push the tire bead down so the bead area

is easier to reach.

7. Move swing arm into place and adjust as described

on page 4, steps 7, 8, and 9. Increase the distance

between the demount tool and the wheel an additional

1/16 to 1/8 inch with the adjustment knob. Locate the

valve stem directly under the demount tool before

proceeding.

8. Insert bead lifting tool between knob on demount

tool and tire bead. Pull lifting tool down over wheel to

lift bead up and over the knob.

NOTE: On asymmetrical hump wheels and stiff side-

wall performance tires, it may be necessary to use 2

optional drop center tools (part #8435685) to hold tire in

the drop center so that the bead can be lifted over the

demount tool.
