Re: TPMS question for second set of wheels
All WK2 wheel sensors are the same, although the STR-8 may be a bit different. . The base receivers in the WK2 provide a simple warning, the premium receivers display the actual PSI.
The tire shop can reset the sensors or you drive 5-20 minutes and they reset themselves. I swap between a set of winter and summer wheel/tires and have had no issues.
My premium system will display the previous PSI sample reading for maybe 5 minutes before sampling and displaying the new tire pressures. It appears to be instant, but it is not really.
Same thing for most Jeeps, like my older KK. There are two sensor frequencies in use across the Jeep line, but all WKs use the higher frequency. There are several other chrysler vehicles that use the same sensors.
