Wheel and Tire: Disassembly

NOTE: Failure to follow the instructions below may result in damage to the TPMS.

NOTE: The TPMS sensor is mounted to the valve stem. Removal of the valve stem requires dismounting the tire from the wheel and removal of the TPMS sensor.

NOTE: Use only the Digital Tire Pressure Gauge any time tire pressures are measured to be sure that accurate values are obtained.

WARNING: Before beginning any service procedure in this article, refer to Health and Safety Precautions . Failure to follow this instruction may result in serious personal injury.
Refer to: DESCRIPTION AND OPERATION .
NOTE: The valve stem is connected to the TPMS sensor. Do not pull the valve stem from the wheel, or damage to the sensor will occur.

NOTE: If a new TPMS sensor is being installed, remove and discard the valve stem-to-sensor screw and the sensor.

Remove the valve stem core and fully deflate all air from the tire.
NOTE: Do not allow the tire beads to move beyond the wheel mid-plane (middle of the wheel) when separating the beads from the wheels, damage to the TPMS sensor may occur.

NOTE: Tire and valve stem position is critical to prevent damage to the TPMS sensor when using a paddle-type bead separator.

NOTE: Some machines may have a nylon roller bead separator at the 12 o'clock position instead of the paddle-type bead separator at the 3 o'clock position.
- For a paddle-type tire machine, position the valve stem at the 12 o'clock or 6 o'clock position and the paddle at the 3 o'clock position.
- For a roller-type tire machine, align the valve stem with the roller at any position.
- If bead separation is difficult to achieve using the nylon roller bead separators due to high anchoring force between the tire and the wheel; the paddle-type bead separator may be a more effective method.
NOTE: Paddle type shown, roller type similar.

NOTE: Index-mark the valve stem and wheel weight positions on the tire.

Place the wheel and tire assembly on the turntable of the tire machine with the valve stem at the 11:30 position and the machine arm at the 12 o'clock position and dismount the outer bead from the wheel.

Reset the wheel and tire assembly on the turntable of the tire machine with the valve stem at the 11:30 position and the machine arm at the 12 o'clock position and dismount the inner bead from the wheel.
NOTE: A new valve stem must be installed whenever a new tire or wheel is installed.

Discard the specified component. Follow local disposal regulations.

NOTE: When installing a new wheel, always install a new valve stem and sensor screw. Reuse the TPMS sensor from the previous wheel if possible. The TPMS will not have to be trained if the sensor is reused.

NOTE: If the TPMS sensor is being reused, inspect the TPMS sensor for damage and install a new sensor as necessary.
NOTE: To prevent TPMS sensor and valve stem damage, the valve stem must be installed onto the TPMS sensor and then installed into the wheel as an assembly.
