I originally blamed the two value stem failures on the centrifugal force on the stem created by the weight of the sensor. No proof just a suspicion. When I bought my Sailuns, had the dealer replace all the valve stems and have had no more problems. I think I would stay with the lighter weight sensor and removal to add air is no different than removing a stem cap.
