These instructions are based on the Hunter TC3900 tire changer. Some steps might be different for other tire changers. Refer to the operator's manual for specific information.

Dismount

  1. Remove the wheel. See Wheel Assembly (Remove and Install).
  2. Place the wheel on the tire changer, with the front of the wheel facing up.
  3. Insert the center clamp.
  4. Tighten the cone on the center clamp.
  5. Remove the valve core, and allow the tire to deflate.
  6. Position the upper bead roller at the edge of the rim.
  7. Rotate the tire to loosen the upper bead. Lubricate the bead as the tire rotates.

    Note
    The TPMS sensor is close to the rim. Do not damage the TPMS sensor when loosening the upper bead.
  8. Position the lower bead roller at the edge of the rim.
  9. Rotate the tire to loosen the lower bead. Lubricate the bead as the tire rotates.
  10. Position the mount head at the edge of the rim, then lift the mount head to hook the upper bead.
  11. Rotate the tire to pull the upper bead above the rim. Lubricate the bead as the tire rotates.
  12. Use the lower bead roller to lift the tire off of the rim.

Mount

  1. Thoroughly lubricate both sides of the beads of the new tire.
  2. If the tire has "outside", "side facing outwards", or a direction of rotation arrow on the sidewall, make sure that the tire is oriented properly.
  3. Push the lower bead of the tire over the rim by hand.
  4. Position the mount head on the upper bead.
  5. Use the bead press arm to push down on the sidewall.
  6. Slowly rotate the tire to push the upper bead below the rim.
  7. Attach the air chuck to the valve stem.
  8. Use the foot pedal to inflate the tire to approximately 40 PSI (275 kPa) and seat the beads.
