Tire Pressure Sensor: Assembly
CAUTION:
Damage to the TPMS sensor may result if the tire mounting is not carried out as instructed.
CAUTION:
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.
- Install a new valve stem onto the TPMS sensor.
Tighten the new valve stem-to-TPMS sensor screw to 13 lb-in (2 Nm). See Fig 1.
- Lubricate the valve stem with soapy water and install the valve stem and TPMS sensor assembly into the wheel using a block of wood and a suitable valve stem installer. See Fig 2.
- Make sure the valve stem rubber is fully seated against the wheel. See Fig 3.
- Position the wheel on the turntable of the tire machine, then lubricate and position the bottom bead of the tire on the wheel.
- Position the wheel to align the valve stem with the machine arm, at the 6 o'clock position, and mount the bottom bead of the tire. See Fig 4.
- Reposition the wheel to align the valve stem with the machine arm at the 6 o'clock position, and mount the top bead of the tire.
- Inflate the tire to the pressure specified on the Vehicle Certification (VC) label located on the driver door or door pillar. Proceed to Step Fig 4 if the tire beads do not seat at the specified inflation pressure.NOTE: Use only the TPM Activation Tool any time tire pressures are measured to make sure that accurate values are obtained.
- The following steps should only be carried out if the tire beads cannot be seated by inflating the tire up to the maximum inflation pressure listed on the tire sidewall
- Relubricate the tire bead and wheel bead seat area.
- Install a remote valve and pressure gauge.
- Wear eye and ear protection and stand at a minimum of 3.65 m (11.98 ft) away from the wheel and tire assembly.
- Inflate the tire using the remote valve and tire gauge until the beads have seated or until the pressure gauge is 138 kPa (20.01 psi) more than maximum inflation pressure on tire sidewall. If beads have not seated, deflate the tire and proceed to the next step.
- Place the wheel and tire assembly in an Occupational Safety and Health Administration (OSHA)-approved tire safety cage.
- Inflate the tire using the remote valve and pressure gauge until the beads have seated or until the pressure gauge is 276 kPa (40.03 psi) more than maximum inflation pressure on the tire sidewall.
- Install the wheel and tire.
- Tire pressure sensor will need to be trained. See TIRE PRESSURE SENSOR TRAINING .
NOTE:
Use care not to damage the wheel surface when installing the valve stem and TPMS sensor assembly.
NOTE:
It is important to pull the valve stem and TPMS sensor assembly through the wheel rim hole in a direction parallel to the valve stem hole axis. If the assembly is pulled through at an angle, damage to the valve stem and sensor assembly may occur.
NOTE:
Do not mount the tire at this time.
NOTE:
Lubricate the tire beads using a suitable fast-drying, corrosion-inhibiting tire bead lubricant.
WARNING:
If there is a need to exceed the maximum pressure indicated on the sidewall of the tire, in order to seat the beads, follow ALL the steps listed below. Failure to follow these steps may result in serious personal injury.
CAUTION:
Do not exceed 276 kPa (40.03 psi) above the maximum pressure on tire sidewall. Install a new tire if the beads do not seat at this pressure.
