    Ask a Question
    • Will the new stem fit wheels with either 8.3mm or 11.3mm?

      Sorry, these units are for wheels up to 6mm (1/4") thick.

    • It appears that there is a temperature reading on the monitor as well as pressure. is that correct?

      Correct. The display will show temperature as well as pressure on each tire. You can change the default setting on max and minimum pressure also maximum temperature.

    • When the battery goes dead do you need to replace the entire sensor?

      there are 2 different types of battery used in this system. the Monitor uses a rechargeable battery that you will charge every 6-9 months. The sensors use 4 round watch battery with 3-year life span. After 3 years, you can change the batteries or purchase new sensors.

    • Will system read pressures before wheel movement?

      yes, as soon as you set up the system, it will show your tire pressure and inner temperature. It is not dependent on the movement of the wheels.

    • Can I connect sensors to an IOS app on my phone rather than having to mount the display?

      The systems with monitore are paired to the monitor. They are not using Bluetooth, but radio waves. therefore they cannot be used by the APP on your phone.

    • How long do the batteries in the sensors last? Are they easily changed?

      The batteries last two to three years.
