Tire extender

[homerbw]

I discovered my inside tire has lost 40psi in 1 mo. Never had a problem until installing valve stem extenders. Why would a valve stem extender cause pressure loss? Tires are goodyear 670 19.5

A lot of people have had the same problem that you might be having. First, they should be the woven metal kind and make sure they are screwed on tight, also make sure that they are attached to the outer support bracket in a way that they won't tend to unscrew with cetrifigel force. If everything else is ok then spray some soapy water on them to make sure they are not leaking.
I have used them without ever having a problem.

I just experienced this same concern last month except my tire went flat overnight. I went through 2 stainless woven extenders and still had slow leak. I verified the leak was coming from the valve at the extender connection with soapy water solution. I pulled the wheel off and took it to a tire shop and had a new metal valve stem installed for $5.
Problem solved!

If they were airless by wheelmasters they will bleed off air if they are not properly adjusted.

Although lots of people use valve extenders, some people have problems with them leaking. That's why I don't use them even though it would make checking pressures a lot easier.

Some of the reasons extenders leak are -
1. Not screwed on tight
2. The extender itself is bad
3. Dirt between tire valve and extender

Your extender is not installed properly or is defective. Take it off and re-seat it on the valve stem. Make sure no dirt in either end.

They are quite reliable but, as with any water or air connection, you have to check for leaks to make sure the installation is properly done.

Homerbw.......I too lost pressure on an inside rear tire...I had purchased 6 new tires in AZ and the dealer used the 7 year old extenders instead on spending $12 on new ones. Two days later one tire down 20 pounds....new extenders, 6 months later, no problems. My advice is to replace them after a few years and always use plain steel extenders. Good luck
