Wheel and Tire: Disassembly
NOTE:
NOTICE:
- Tire Changer:
- Tire Balancer:
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.
- Remove the wheel and tire. Refer to: Wheel and Tire .
-
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.
-
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.NOTE: Paddle type shown, roller type similar.
-
NOTE: Index-mark the valve stem and wheel weight positions on the tire.
- 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.
-
NOTE: Use care not to damage the wheel surface when removing the valve stem.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.
