    Per the manufacturer: "Transmitters may be used on rubber valve stems. We highly recommend the brass or stainless steel.

    Rubber valve stems can be an issue, based on the Age, length and physical location (i.e. exposure to road salt, high heat, sun, etc), so be sure to check the condition of you rubber valve stems on a regular basis."

    The screen shows all tires programmed by me but does not scan unless I press the top button. Is this the way it works?
    The monitor and sensors communicate every 6 seconds, but regular pressures and temperatures are updated on the monitor every 4 minutes if a change has occurred. Should a significant abnormality occur, the monitor will react within 6 seconds. This process helps extend battery life on the sensors and monitor.
