The Hummer also has sensors, and yes atleast the H1 could inflate and deflate the tires from inside the truck. I don't know if the H2 and H3 have the same system.

Do a search of this forum for "tire light" there are atleast two threads that have a lot of good information.
Hmm.. just because someone you read it somewhere doesn't mean it's good information. I call BS.

Okay, assuming there IS a sensor on the back of the valve stem, how does information get back to the computer? It ain't wireless! wink

You'd either have to have special rims for the system to work, or you'd have to diconnect some wires every time you change your wheels - and what would the wires look like after how many revolutions? You'd have to use brushes like in an electric motor to get the electrical signal past the fact that your wheels are rotating so much. Also, if the system compared actual pressures, it wouldn't take 'a few miles' to turn off.. it'd know immediately, don't you think? C'mon, think a little more critically about it, and it makes sense that this calculation is done based on rotation of the wheels.
