I replaced the tires after 7 years with absolutely no problems in December. @ months ago I got ready to go on a trip and found the left inner rear flat. Called out a tire service, and they said the only problem they found was the valve stem extension could be removed by hand. Then last Monday I was taking the coach to the shop so I checked the air Sunday night everything good. I get to the shop Monday AM they ask if I knew the RT. rear inner was flat, they said once again they were able to remove the extension by hand.
I guess at this point I am getting gun shy about checking the air. Twice after checking I ended up with a flat. Should I change the extensions? Should I be ok now that I have them tight?
I plan on buying a monitoring system, between this and another issue I had recently I really see the need more than ever.
Thanks,
Jerry
Did they replace the valve stems with aluminum ones when the tires were renewed? We did, as well as 12 wheel studs. Might check. ^.^d Here's a good company: Tire Pressure Monitor - TPMS Sales (http://www.tirepressuremonitor.com)
We use extensions on our road trucks and my coach.. Checking 18 tire pressures x 20 can be a bear without them but they come with a negative of one more connection for a leak. Keep them tight.
Or, remove them, air to correct PSI and install a TPMS.
Same here . The only low tire had a loose extension . Add a wee bit of rtv to the stem threads. Very carefully keeping the center clear of course .
I am waiting to purchase the cats eye connectors but keeping the fittings tight applies there and also with any external tps system .
I had issues until I installed the extension supports in the front wheel hole the extension passes through.
Rubber piece. Fixed
Let us know how the cat's eyes work out; they look pretty cool.
I forgot to mention these that we have these on board. Work great with our compressor! Not installed on outside duals because of the 90 degree offset (which are a bearcat to inflate/deflate/check).
I have them they work great.

The inside dual wheel extensions I use (see photo) have a place at the top and the bottom with wrench flats. I also have rubber centering inserts, and TPMS sensors. If I need to remove the TPMS sensor from the extension for any reason, I hold a backup on the extension with a small wrench. This prevents it from backing out and getting loose. Haven't had any problem with leaks.
Jerry,
Here is what we use to eliminate the extension.
VH515S7T 7-1/8" Eff length reverse mount .625 truck valve (http://yourtireshopsupply.com/product/1405/vh515s7t-length-reverse-mount-truck-valve-vh515s7t)
Shop around as the last I got were ~$12 each

I had two inside rear tires go flat because of the extensions. I took them off and bought a straught inline inflater chuck and a straight inline air gauge. No problems since.
I used them for a short time, until they caused 2 tires to have slow leaks due to dirt and grit. Sooo now it's metal caps all around no problem in the last 10 years.
I use cross fires. Have had flats/blowout and they isolated the other wheel fine. No leaks at all. Love them...I run 100psi all around: Amazon.com: Crossfire Dual Tire Pressure Equalization System, 100 PSI, one... (https://www.amazon.com/gp/product/B0003040ZS/ref=od_aui_detailpages00?ie=UTF8&psc=1)
I had a similar problem. What we found was that the extension had worn out the plastic rim/seal. You could see where it was not completed. I bought 2 new ones from Foretravel and problem has not recurred. If you call Foretravel parts, know what size your holes in the wheels are.There are 2 sizes and the extensions come with the rubber inserts. But they need to know size.
