Tire valve extenders

[txc2936@yahoo.com]

So, i had the valve installed yesterday, Now the tire is at 20 PSI, and bubbles coming from the valve stem base. This is concerning because i went to a reputable tire shop. Starting to be very concerning. Do i need to go to FORD service?

Take it back and make them do it right

I just emailed them. There was a comment in the posting, that this isn't as easy as it looks and finding someone to do it right is tough. The bubble now was similar to a kids bubble toy, A VERY large bulb was coming from under the washer.

I requested they send the mobile unit to do the job, we are rapidly eating my $$ credits with this outfit!!

It’s not rocket science. How old is the wheel? Is it rusty? Maybe a newb at the tire shop forgot to put the inner grommet on the stem first.

9000 miles on RV. I didn't see corrosion. I will spend the day... finding out;....

Did you try tightening the nut to see if the leak stopped, 35 to 55 inch pounds

Thanks Jimbo...The mobile unit came to RV park, and the issue was the mechanic installing valve stem, over tightened the nut, extruding the rubber on the inside of rim. A rookie mistake for sure! My aviation teacher used to say. Don't torque bolts until they become loose!

A before and after picture below. 1/2 hr for an experienced tire mechanic.

He must have used an impact wrench, lol

ah, i bet his boss will be talking to him today. Sent all the photos.

It looks like we have this one solved. All tires holding 82 PSI,

it's all about getting these things fixed and getting to play another day....

[txc2936@yahoo.com]

Tire was leaking again, about 1 lb per day. I removed the tire pressure extender, filled tires and let it sit for 2 days. Pressure is equal, I figured its in the tire pressure extender. I re-attached and thumb tightened only. This seems to have worked. This is the toughest problem to detect. I would have rather the tire picked up a nail, and easily plugged.

Would putting a little sealant around the threads work, or just leave it.

[ducksface]

I'd wrap the threads.
But I bet the problem lies in that the original valve stem isn't meeting the o ring in the extender.
The extender should bottom-out on the lip of the valve stem.

I have some long thread valve stems and some short threaded valve stems.
I don't know why long threaded ones exist but the cap bottoms on the nicely. My short threaded ones the stainless cap kinda floats. I'll try to get pictures.

I counted up tires a while back. Things that need air including bicycles and furniture dollies...76...probably more since my last count.

[txc2936@yahoo.com]

Ok will do.. thanks, i will check extender and valve threads. I just dont want to over torque. This causes leaks also. As someone said, this isn't rocket science. I am forced to keep testing and checking.

Thanks to a pro tire shop here, they re-balanced my tire and installed the tire pressure extender. Looks like the other mechanic just kicked the balance wts under the truck when they fell off the rim, I'm now in that elite club. I wont ever go back to that repair shop!!

He suggested on the tire pressure extenders, just finger tight, and then 1/2 turn more to secure. It was alot easier with wheel off the RV. He also used a torque wrench in tightening the wheel lug nuts. Wow, a mechanic that actually uses an old fashioned torque wrench.

All holding 82 PSI.. Ready for my adventures next week in Huntington Beach, SC.

Never ever more than finger snug the extensions. Over tightening compresses the gasket just like the guy did with the valve stem.

Glad you’re fixed up. But don’t be surprised if they start to leak again. Valve extenders are notoriously unreliable. In the meantime I hope you’ll consider a good TPMS. I use the TireMinder i10 and it works a treat. So accurate that I hardly ever check with a gauge anymore. If (when, maybe!) you give up on the extenders a more bulletproof solution is actual dually valves. Cost more but mine have never disappointed. Enjoy your travels.

Pete I just did a search using dually valves and there is a brand of valves by this name.
Do you use dually valve brand or are there others you recommend?
It looks like this is a better solution than the flex screw on type of extender.


Any suggestions on brass vs chrome?

I have chrome ones from https://yourtireshopsupply.com/categ...lly-valve-kits. It’s not a cheap or easy project as the tires need to be removed from the wheels. The valves cost about $120 and installation about the same. But I’m glad I have them.

Hi Thor shipped me free value extenders for vegas 25.6

My experience with valve stem extenders has been similar to others here in that they sometimes leak if left on, so I use them to check/fill the tires and then take them back off.
