So what happens if you take out the valvestem sensors and replace them with garden variety 69 cent rubber ones? eventually the batteries will go dead in them, right? somebody will probably have a dongle or hack to fool the central unit eventually. i dont like the hard metal stems. a rock caressing the sidewall might snap that right off. what happens when the spare is mounted?

all this because ford sold underinflated explorers off the showroom floor? probably adds $100 to the cost of a new car.
