Valve Extenders

When the shop replaced my tires, they did not secure one of the rear supplementals, I call it a "hubcap". While on a trip, it came loose. the braided valve extender was what held it in place, however the stress caused the extender pull the stem out of the valve. Luckily we caught it and after 3 hours back on the road. I took it back to the shop and they resolved the problem with the supplemental, and sent me on my way. I have been reading thie forum so I immediatly ordered the TST TPMS....When i attempted to install the monitors, I discovered when the shop replaced the tires/valves, the only way to add air is to remove the supplemental, I am new at this, are the braided valve extenders safe? Will the monitors work with the extensions? Are there other options...we are at our wits end

We use the TPMS with extensions but you need to monitor it for a while to make sure they don't leak. I had one that wouldn't quit leaking until I just replaced it. I also got tired of trying to find high pressure air at truck stops and purchased a small pancake compressor that I carry in the basement. Works great.

On my last motor home a set of the airless braided metal covered extensions cost me two tires. My current motor home came with a set of air versus airless extensions that worked okay for seven years as far as I had no air loss due their use. They were still difficult to use - I needed one more hand when adding air - and were hard to secure properly with the Pressure Pro sensors installed. I had to use cable ties and wiring loom to keep the extenders from rubbing on the metal wire clips that held the extenders in place where they came through the wheel cover. When I had new tires installed I bought a set of DuallyValves from Borg Tire Supply and had them installed at the same time. Very easy to add air and the sensors don't bounce at all.

My experience which is on going, the TST flow thru sensors work on the original valve stems from Spartan. However the inner duals with valve stem extensions do NOT work with the flow thru sensors. I purchased new extensions from Always Shinny Wheels RV. They appeared very good quality but they did not work either, however they make rubber disc that fit into the thumb holes that hold the extension nicely in place. I experimented with just the toad caps that did work or were within a few psi on the inside duals. So, Mike at TST who is great, took the sensors back to check them and is sending the toad caps to try on the inside duals. I really don't mind removing the toad caps as I have to remove the valve covers to fill with air anyway!

I agree with Clay L. Get rid of the extensions and get some solid metal dually valve stems.
