  1. After dropping the tire pressure warning valve into the tire, disengage the tire bead using the shoe of the tire remover.

Notice:

Be careful not to damage the tire pressure warning valve because of interference between the sensor and tire bead.

  1. Remove the bead on the upper side.
  2. Take out the sensor from the tire and remove the bead on the lower side.
  3. Remove the inner grommet from the tire pressure warning valve.

Hint:

Check that there are no cracks or damage on the grommet. If necessary, replace the grommet, the washer and the nut.

Installation

  1. Install tire pressure warning valve subassembly

  1. Insert the tire pressure warning valve into the valve installation hole. Insert it from the inside of the rim so that the print surface can be seen.

Notice:

  1. Install the washer on the tire pressure warning valve from the rim side and tighten it with the nut.

Torque: 4.0 N*m (41 kgf*cm, 35 in.*Lbf)

Notice:

  1. After the tire is inflated, the valve nut may be loose.

    Retighten the nut to the specified torque and then check for air leaks with soapy water.

Torque: 4.0 N*m (41 kgf*cm, 35 in.*Lbf)

  1. Set the wheel disc to the mounting machine and install the lower tire bead. Position the main body of the valve sensor in the shaded area shown in the illustration.

Notice:

If the valve sensor is positioned outside this area, it will interfere with the tire bead and may be damaged.

  1. Install the upper bead.
