Small valve extender on E450 RV Tires

Airing up the tires on my Jayco Grayhawk on a Ford E450 frame. I noticed the six RV tries all have an air valve extender (about 1 3/4" long) on the steel tire valves. The extender has a small ball valve in the very tip.

Can anyone tell me the importance of that small air valve extender....???

My dual lies had the short extenders on them, which I had to remove for my toms to work because the extenders were not pressurized. Valve extenders have been a point of contention for many RV owners as they can leak and next thing you know boom. As I put my toms on quickly, I can't say much about the extension valves, but they likely only let air through when you put an air chuck to them.

OK ..... I broke down and called my favorite tire dealer. He said that any tire with more than 50 lbs is considered a "high pressure tire".

Because our tires hold 75 & 80 lbs, those little valve extenders are high pressure safety features to help keep the air valve from exploding or losing air. I guess that makes sense, so I will keep them on. I had seriously considered taking them off.

Thanks for the post .....
