As follow-up to my question about the merits of the two types of rear wheel valve extenders (airless vs. air-filled) that can be used with a TPMS system, I called a TPMS manufacturer yesterday to see what they might say. While they said that their wireless pressure sensors will work with either, the specific statement regarding airless extenders was
So I think that on the rear tires I am going to change over to air-filled. They have a robust depressor design that once fully screwed onto the tire's valve stem pressurize the extension and keep it protected via the metal braiding.
If there are other comments out there, I'm interested to hear.
We've worked with these airless extenders before... To be honest, I do not like them. The metal rod that runs through the depressor commonly misses the tires valve stem (after a period of time being depressed) and gets jammed beside the original valve core causing leaks. We can work with them as we would depress the internal rod, and in turn depress the original valve core. You are exactly right though this would render the airless extender moot as it would constantly hold pressure. We usually work around this by offering a different extension (air-filled)...
