There is only 5 spots in the tpms ecu. It is in the online FSM.
Your stock tires have 4 of those spots taken up.
If you have a pre-09 truck, then all 5 spots are taken (including the spare sensor).
You will have to have your codes from the winter set reprogrammed every time you swap the rim/tire set or buy a code machine & do it yourself. Apparently they sell one online somewhere or talk the installer into doing the reprogramming. You will have to get the codes out of the stock tires.
Do not know if you can get that without breaking them down or from the dealer or what.
I run two sets of tires/rims and only one set of sensors.
My stock set of rims & sensors were steel. Perfect for winter tires. Plus it is nice having the tpms in winter. Summer I can deal with no sensors.
I do not trigger a light when my summer set is on unless I get out of range of the winter tire set stored in the shed.
The range is pretty far.
If it does trigger, I put a card over the light until I return home. It resets overnight and has done this going on 4 seasons.
Now if you want to run two sets of tires & rims with sensors. The reprogramming is the only way it works besides buying the new tires, rims, and sensors.
