| *a | Tire | *b | Shoe |
| *c | 10 to 20 mm (0.394 to 0.787 in.) | - | - |
| Cutting Range | - | - |
(1) Remove the tire valve cap.
NOTICE:
Keep the removed tire valve cap.
(2) Remove the valve core to release the air from the tire.
NOTICE:
Make sure that a sufficient amount of air has been released.
(3) Using a tire remover, remove the tire from the disc wheel.
NOTICE:
- Be careful not to damage the tire pressure warning valve and transmitter due to interference between the valve and the tire bead.
- Set the tire remover shoe as shown in the illustration.
(4) Using a T10 "TORX" socket wrench, remove the bolt and tire pressure monitor sensor from the tubeless tire valve.
(5) Cut the tubeless tire valve and remove it by pulling from the outer side of the disc wheel as shown in the illustration.
Installation
INSTALLATION
CAUTION / NOTICE / HINT
NOTICE:
- Always use a new bolt, tubeless tire valve and valve core when installing the tire pressure warning valve and transmitter.
- Make sure not to damage the urethane covered backside of the tire pressure warning valve and transmitter (the surface opposite to the side with the ID code) with anything sharp.
- Write down the ID number before installation.
- Check that there is no oil, water or lubricant around the rim hole and tire pressure warning valve and transmitter. Failing to do so may result in improper installation.
- Use only a specified tire valve cap. If an unspecified tire valve cap is used, it may seize to the tire pressure warning valve and transmitter.

1. INSTALL TIRE PRESSURE WARNING VALVE AND TRANSMITTER
| *1 | Tire Pressure Warning Valve and Transmitter | - | - |
| *a | Printed Surface | *b | 7-digit Transmitter ID Number |
| *c | Rim | - | - |
(1) Using a T10 "TORX" socket wrench, install the tire pressure monitor sensor to a new tubeless tire valve with a new bolt.
Torque:
1.2 N·m {12 kgf·cm, 11 in·lbf}
(2) Write down the 7-digit transmitter ID number shown in the illustration.
(3) Insert the tire pressure warning valve and transmitter from the inside of the rim.
NOTICE:
- Make sure that the tire pressure warning valve and transmitter is installed so that the printed surface can be seen. If the tire pressure warning valve and transmitter is installed upside down, it may be damaged or fail to transmit signals when driving at high speeds.
- Check that there is no deformation or damage to the tire pressure warning valve and transmitter.
- Check that there is no foreign matter on the around the rim hole.

| Area for Tire Pressure Warning Valve and Transmitter | - | - |
(1) Set the tire and disc wheel onto the mounting machine as shown in the illustration.
NOTICE:
- Position the main body of the tire pressure warning valve and transmitter in the area shown in the illustration.
- If the tire pressure warning valve and transmitter is positioned outside this area, it will interfere with the tire bead and may be damaged.
(2) Apply a sufficient coat of soapy water or equivalent to the tire bead and rim.
NOTICE:
Do not apply soapy water or equivalent directly to the tire pressure warning valve and transmitter.
(3) Using a mounting machine, install the tire to the disc wheel.
NOTICE:
- Make sure that the tire bead and mount tool do not interfere with the tire pressure warning valve and transmitter.
- Make sure that the tire pressure warning valve and transmitter is not clamped by the bead and rim.
(4) Install a new valve core.
(5) Inflate the tire to the specified tire inflation pressure.

(6) Check the surroundings of the tire pressure warning valve and transmitter for air leaks with soapy water or equivalent.
- If air is leaking from the valve core, press the valve core several times to remove foreign matter. Replace the valve core as necessary.
- If air is leaking from around the tire pressure warning valve and transmitter, check if the tubeless tire valve is not deformed, damaged or contaminated with foreign matter. Replace the tubeless tire valve as necessary.
(7) Install the tire valve cap.
