Inflation (1-4 For bead sealing only)
1. Connect the inflation hose to the tire valve
stem. Hold the tire up against the upper edge
of the wheel. Be sure the top bead of the tire is
over the bottom of the valve stem.
2. Depress the inflation pedal to position 2 and
hold about 1 second to begin air flow, then
depress the pedal to position 3 and hold very
briefly–less than 1 full second to seal the
beads.
3. Release the inflation pedal and allow it to
return to position 1. Verify that both beads are
completely sealed to the wheel.
4. Once tire pressure is indicated on the air
gauge (with the inflation pedal in position 1 and
foot removed from the pedal), unclamp the
wheel from the clamps.
5. Remove the tire/wheel from the tire changer,
reinstall the valve core (if it was removed), and
place the assembly in an approved safety
cage.
6. Use an air hose equipped with a remote
pressure gauge and valve.
7. Apply air pressure to the tire in short bursts,
checking the air pressure in the tire in between
bursts. Attempt to seat the beads without pres-
surizing the tire any more than necessary.
Once the beads “pop” into their seated posi-
tion, stop the air flow to the tire immediately.
8. Verify that both beads are fully seated. When
both beads are seated, the tire is ready for
inflation. Leave the tire in the safety cage for
inflation.
9. Adjust, per vehicle specifications, the air
pressure inside the tire.
All EMT/RunFlat inflation must be completed in a
safety cage except for bead sealing. Bead seal-
ing is typically not a problem when inflating
EMT/RunFlat tires.
