I'm thinking about changing wheels on my 07 GT. My local tire store hasn't got a clue about the new 2007 tire pressure monitoring system, so I definitely won't be using them for the change. Does anyone have any experience with moving the factory tire pressure monitors to either aftermarket or different OEM wheels? Did you have to buy new attaching hardware, or can you use the hardware that came with the factory wheels? Thanks in advance.

Have you looked at the system on the chassis yet? I do not see a reason that they are "with the factroy wheels". One of my GM cars that has it uses sensors on the a-arms. They don't "know" the tire pressure but it "knows" the difference between the four sensors. I suggest that you take a looik at it and see if you can determine how it is registered with the PCM.

You're right... Maybe Ford does it differently but if it's configured the same as my old Pontiac, the system monitors rotations of each wheel by means of traction control/ABS sensors. If one wheel rotates faster over a period of time, the system assumes the air pressure in that tire is lower than the others.
Unlike the TPMS systems in my Charger, where the sensor is integrated into the valve stem, Ford attaches the sensor to the rim by a band that goes completely around the rim (there's a diagram in the owner's manual that shows the sensor). The sensor alone costs $50 each (one per wheel), and the attaching hardware is $50 per wheel, so I was looking to reuse my sensors and attaching hardware if possible.

I had changed out my rims on my 07'GT.Discount Tire found a band kit that replaces the stock one time band.You can use the stock sensors on this replacement kit and reuse the band kit.I'll get the info for you later this morning where you can get the kit.Poco
CRAZY!!! Why didn't they use the ABS tone rings.... I think they did it wrong, but what do I know....
Makes no sense to me either. Just complicates wheel changes. Old GM way of using the TC/ABS sensors works fairly well. Don't know what this improves. Maybe it's more accurate??
There's a reason manufacturers are now using internal sensors.
The ABS sensor system is very imprecise: the tire has to be 25% low (8 pounds on a 32 PSI tire) before the system alerts the driver. On a TPMS with the sensor built into the tire, the system can detect a difference in pressure as little as 10% (3 pounds on a 32 PSI tire). For those of you with 40 series tires or lower mounted on expensive rims, the difference between 25% and 10% could be the difference between a trashed rim and one that doesn't get trashed when hitting a pothole or a large object.

Well that answers the accuracy question. That's much better.
so will the band off of a 17" oem rim be able to adjust and fit on an 18" rim? thanks.
The answer to your question is "No". According to the parts department at my dealer, the bands come in 16", 17" and 18" sizes to fit the different sized rims.
