So WK2jeeps.com says that when "installing" new TPMS into the wheels that you need to have them programmed, but I have seen a couple posts on here reporting that you just add them and it automatically adds them.
I am going to pick up a set of winter wheels - so:
1) Does it automatically learn them?
2) If it doesn't, and they need to be programmed, does it need to be reprogrammed every time wheels are swapped, or can it remember both sets?
3) Lastly, do the 2014's use the same TPMS as the 2011-2013? 56029398

The sensor IDs can also be programmed using the TPM-RKE Analyzer Tool. Scan each TPM sensor at each road wheel, and store each Sensor ID in the correct location. (LEFT FRONT, LEFT REAR, RIGHT FRONT, and RIGHT REAR) Connect the TPM-RKE Analyzer Tool to the Scan Tool. Then follow the programming steps outlined in the diagnostic Scan Tool for “Program Tire Pressure Sensor ID w/ TPM Tool” .
