Anybody else dumb enough to take the factory green valve stem caps off and replace them with after market ones that SIEZE UP AND CORRODE???? ???

Yeah, that’s a big no-no. Steel and aluminum do not mix well.

That I knew. Lol. Really didn't think anybody would be du.b enough to make them. Ugh. Going to be a bitch trying to get them off.

Your dealer must have nitro filled your tires. I didn't get green caps.

Brass valve stems can be problematic with aluminum caps. These are brass, not steel.

There are videos out there on this very topic because of dissimilar metals, moisture.

Brass valve stems don't get along well with aluminum. Stainless steel is bad with aluminum but mild steel is ok with aluminum.

Sadly many fancy caps are aluminum and many valve stems are brass. Galvanic corrosion even with only WATER and nothing else.
The aluminum will corrode more because it is more anodic than brass, and will also corrode where it contacts the brass since brass is more cathodic.

steel and aluminum are relatively compatible so if they were steel, then ok - but valve stems are not typically steel - it would rust. And stainless steel and aluminum together is bad.

Brass is incompatible with aluminum, per Mil-STD-889

The caps on my truck are green on the end. They are chrome plated plastic, and not nitrogen filled. Same caps on both of my JTs.

I got hosed then...my 20 JTO has boring ol' black plastic caps. Wife's 21 JL same, just a boring ol' black plastic cap.

Black plastic caps for the "W"

Good enough for me - both my 2020 Overland and this 2022 Overland have these ->

They did. At least give some damn black replacement caps so my shit don't look weak. Lol

I'm going to try helium in mine - should be better mpg.

LMFAO

The dealer put nitrogen in mine, so it came with the green plastic caps. The take-offs I bought came with the black plastic caps. I've had two tires patched that picked up nails. I just use regular air to top them off. After 3.5 years, I'm not sure how much nitrogen is left.

This thing just floats over bumps!

Hmm I did get the A/T duelers instead of the H/T. Maybe that's the difference. Same on the JL. Shenanigans, jeep owes me 9 fancy valve stem caps!
