Can't add air to inside tire

[hutchg]

I was checking the air pressure and topping off before a trip. All was fine until I got to the right rear inside tire - I can't seem to get air to go into the tire. Would this be a valve stem extension issue that I can fix?

Thanks

Some extensions are just a waste of money and materials.

If your hands and arms are small enough you should be able to lie down and reach between the tyres into where the valve stem is and check whether there is an extension fitted.

(I won't suggest that the valve cap might be still on, but it is a possibility)

I've heard/read that sometimes some extensions can be screwed on too tight, causing the rubber washer between the actual valve and the extension to spread from the crushing, and affecting the ability to get air into the tire.

Had that happen to me. Unscrew the extension and look closely for a small black o-ring either jammed in the extension, or remaining on the inside wheel's valve.

Ok, went to look at the valve extender. Turns out that it just wasn't screwed on enough to make the proper connection. Works great, now!

Now, I just need to get the coach weighed so I can get the correct tire pressure.

Had the EXACT same problem. Turns out that he extension was just a little loose - not enough to leak very much, but enough to not let me put air into it. Take it to a shop (if you don't want to remove the wheel yourself), they'll take the outside tire off and tighten or replace the extension. My shop didn't even charge me for it.

I have filled hundreds of tires.If you need to tighten the extension, you only need to remove the wheel cover, not the wheel.

True enough. But it was a younger guy that didn't really know what the problem was, so he took the long way through the process. And yet they still didn't charge me anything!

On the subject of rear dual tires, why is the outside tires valve stem pointed in? I never knew if there was a reason or what?

The outside stem is pointed in because the rim is installed backwards and so you can rotate the tires without changing the valve stems.
