General Discussion / Re: Valve Stem Extensions
« on: January 28, 2025, 07:06:55 pm »The Borg extensions work fine for me. The inner valve extension comes straight out and has a plastic/ rubber insert to stabilize it.
I know. And I agree. Several vehicles and many miles have proven to me that solid valve stems, without extensions, are reliably trouble free. Getting a tire shop to install them is what I find most challenging.
The flexible valve core extensions on my current PC look a little bit like celery stalks with broken and frayed fibers protruding in every direction. I think I am about to experience their failure. From the reports, it appears the braided extensions are not only apt to fail, but they also actually do - with regularity. Contrarily, I recently started noticing long haul semi-trailers, with huge wheels, are now equipped with hub mounted TPMS that are connected with much longer braided extensions than mounted on 16" PC axles.
I need to investigate what significant difference there is. Obviioulsy, the million mile users have confidence in the flexible extensions.
