Tire Pressure Monitoring Sensor (TPMS)
The OEM TPMS must be replaced with a sensor that is capable of operating at the higher
pressures required for the 245/70R19.5” tires that are recommended for RAFNA Railgear
Wheel Modification Kit.
The OEM sensors cannot be reused as they are a snap-in style that will not mount to the steel
wheels supplied with RAFNA Wheel Modification Kit. A screw-on type that is secured to the
steel wheel with a nut on the outside of the wheel is required.
Installation of Tire Pressure Monitoring Sensor (TPMS)
1.
Remove the small rubber grommet from pressure sensor valve stem and discard.
Replace the small rubber grommet with the large rubber grommet supplied with this kit.
2.
Assemble pressure sensor, grommet, washer and nut to the 19.5” wheel as shown in
Figure-1.
3.
The valve stem nut should be torqued to 24-30 in. lbs. This is to ensure the proper
operation of the sensor and to maintain and air tight seal with the wheel.
4.
It is recommended that the speedometer for the vehicle be recalibrated for the 19.5”
wheels and tires. There is currently no option in the vehicles computer for 19.5” wheels,
the closest available setting is for 20” wheels. Using this setting should achieve a 3-4 mph
variation from actual at highway speeds.
