So there was some question about the TPMS Sensors on the 2007 model Tracs. here's what I have found out.
The sensors installed at the factory, cannot be reused, however, if you have to get them replaced (hopefully under warranty), the ones that get put on afterwards are removable and reusable. THey are held on with metal bands that use a screw to tighten them (like ones on belts under the hood sometimes (the technical name is escaping me right now).
I recently switched from my 17 in factory rim to a wider 17 in aftermarket chrome wheel and the sensors were able to be switch with bands and all. Here's a picture of the after market rim
