    FWIW, I've seen TPMS act a bit different when the tire is rolling than when stationary. What I did to test mine is pump it up to 60. I then calibrated the system to the new pressure as per the owners manual. I then dropped it 5 psi for each commute to and from work.

    Got a light heading out of the garage (after the tires started rolling) on the 5th commute (40 psi).
