Those with A3 rims that don't leak... Clamp ring tightness

I think I found the leak. Bubbles are coming from one of the fittings I used to install the Schrader valve. I'm going to tighten it up and see if that stops it.

I soaped this several times and now it's making bubbles! :cookoo:

Would really like to know exactly what it was that was leaking.
HAPPY for you that the dang thing isn't leaking anymore!

I think we are using too tight of a bead-lock.

I don't think it's leaking anymore because the tire pressure I just read isn't lower than it was 16 hours ago. I'll know for sure when I air it back up to 50 psi.

This is my current setup:

I'm using the existing air pipe and elbow, and installed a 3/8" x 1/4" bushing with a 1/4" x 1/8" bushing installed in that, with the original 1/8" Schrader threaded into that. Everything has Permatex thread sealer applied. Despite that, the leak was at the 1/4" male threads. Fortunately just turning that fitting a quarter-turn seemed to solve that - we'll see!

I did it this way because my closest hardware stores don't have 3/8" x 1/8" bushings in stock. So I created an additional leak point because that's what was available at the time :( I found that Lowe's actually has them in stock a half-hour away, so I'll be making a trip out for them soon. Moving forward I'll be cutting out a leak point with the new bushings.

I'd really like to know the engineering thoughts of this rim design. The 5-ton bolt-together wheels don't seem as daunting to work on, yet they are for a truck with half the cargo weight capacity? Whomever approved this design for the A3 was on the crazy train IMO.

We got rid of the Cits? System, installed the
53” tires, cut down the headlock so they were
1 1/4”?
and used sealer on the o rings and valve stem mount
No leaks in 4 years.

Sorry didn’t make it clear, 1 1/4” narrower?

So far, all of my leaks have been related to brass fittings either failing or not being tight enough. My o-rings and grommets aren't leaking as installed per the TM :)
