Is there a trick to checking rear tire pressures

Anyone know of a way to check the rear inside tire pressures. Neither of the inside tire extenders work at all. We can't get a reading.

HERE is a blog post on hose extenders. Note the outer ends are firmly attached (pop rivets)

You can send me email if you need faster reply. Email is posted under my picture on the blog.

Mgs Forrester valve stems

If they are still using the limp fiberglass valve stems, ditch them and get steel. The originals were nothing but trouble.

13STL, my dual extenders wouldnt let me check pressure either. I took my extenders off and use a truck chuck/gauge with a straight end. Works great to check and add air. The simulators had to come off to get my hand through to remove them, but once off, I put the factory caps back on and reinstalled the sims. I can now check and add with Sims on.

I use extenders, but in a different way. On our old Four Winds/Ford, it had the tiny "hand" holes (The ford "engineer" who came up with these should be made to check every RV in the world) so I had to come up with another method without using permanently installed extenders.

Here's the tools:



Short permanent extension on outer dual - I had rubber valves, so I added a small support wire:



View through the "hand hole" to the inner dual schrader valve:



Using the length of 11/32" rubber hose, remove the cap:



Cap removed:



Using the long neck dual foot valve gauge, check the inner dual:



If the tire needs air, screw on the extension. The female end is fixed, so it can be rotated using the hose:



Extension attached:



Attach your compressor and fill to the desired pressure + a pound - it helps to have a screw fitting, rather than the press-on style:



I add a pound extra to compensate for the lost pressure when unscrewing the compressor/extension fittings.

I put the same style extension on the outer dual of our new Sunseeker and will use the same process. I have the new Pacific Dualies wheel liners, and the hand-holes are about half of the size of the original GM hand-holes:



Hope that helps!

Very good job of addressing the poor design. Valve support are good temporary fix till metal stems are installed in the wheels. Few people think of the stress they are placing on valve stems when they push on it with pressure gauge or air chuck.

One suggestion. Change the caps from plastic to metal. If the core develops a leak the plastic will not retain your 80 psi but metal caps with internal O-Ring should.

Our new Sunseeker has all metal caps - and we no longer own the Ford... so that is the new owner's issue.

Also, the Sunseeker has metal stems as, I suspect, they are part of the TPS system.
