Hey,
I recently bought a 2007 Suburban. The sub came with 17" wheels from the factory. I just swapped for some 2007 20" factory pickup wheels. I'm assuming the 20s have sensors in them also. What do I need to do to get the TPMS to read properly? The system appeared to be working properly earlier except for the left rear had no pressure reading. I tried the procedure in the owners manual to reset and didn't work. Then later this evening I had to run somewhere and none of the sensors were registering any pressure. Can the dealer recalibrate or do I need to break the tires down and get the serial numbers off of the sensors?

Thanks,
Mark

 

I also wanted to say. I am not getting any warning lights or messages.

Thanks,
