Tire valve extension
I'm having a problem with the driver side inner rear tire. It has a valve stem extension and doesn't leak air. However when I attach a tire pressure sensor it loses air. I've switched sensors and determined the sensor is ok. What I'm thinking is the extension is not normally pressured but when the sensor is attached it is pressured and leaks at the connection to the valve stem (which I can't see).
Is there a certain type of extension that is designed to remain pressured up?
Thanks,
Forest
