Hi Roy,

Yup, your notice a leak most of the time by feel. But then again on logging roads not so easy, so there is that. You know that for me a big portion of desire for the system was the diddle factor. Just something to play with. I was maybe hoping it would show any wheel temp differences, but if I thought that through more I’d have realized that the wheel has to get quite hot before it affects the stem mounted sensor, the sensor being cooled in the airstream.

:-)

Ps oh Frank, haven’t had any leak down issues with my sensors, 6 months now. They do have locking rings to reduce the chance of the sensors unscrewing .
