I recently obtained a Rubicon. Does anyone know if the spare tire has a TPMS sensor in it? I wanted to use the spare in the tire rotation pattern.

Yes, but it is ignored because the tire does not rotate when driving.

In regard to your JL's TPMS:

How does the JL/JLU know which tire/rim/wheel is where .....

Well, there are 3 sensors on the chassis that monitor the 4 TPMS Sensors found on the 4 tire (rim) positions.

Info from the 3 chassis sensors is transmitted to the Wireless Control Module. There is no need for a 4th chassis sensor as the computer uses the process of elimination to determine the fourth tire location.

Yes, your JLU/JL knows exactly which rim is where, within seconds of a tire rotation for example. Yes, It's all done automatically.

There is a TPMS sensor in the factory mounted spare but it is not read by a chassis sensor/ considered by the computer until it is placed in one of the 4 tire positions.
