Another issue with them is when you get tires repaired or replaced. I had nice caps on my last two trucks so I would just remove them before I went to the shop. I don't like the larger caps. the weight can bend the stems down at speeds and cause a slow leak.

I just got the longer plastic ones from AutoZone, like $8 I think for them. Got tired of people stealing the green cap ones off mine, not sure what that's about. Plus no nitrogen in my tires now that I know of.

Put the green caps on. It lets everybody know you are a baller running that expensive dealership nitrogen.

More useless information on valve stem caps.
Aircraft tires use nitrogen, they use nitrogen because it is more stable with temperature fluctuations. When I serviced a tire I would have to take the ambient temperature and barometric pressure then look at a chart to adjust to the correct pressure. Of course this was all documented and inspected. They used o ringed brass caps.
A friend of mine was a club racer (motorcycle) and for safety he had to have metal caps with o rings. The speeds that were achieved could depress the valve by centrifugal force and release some of the air, so o ringed metal caps were required.
My Jeep has plastic caps and I really never gave it much thought, they keep crud out so good enough enough for me.
Your trivia for the day.

Thanks! I am now ready for Jeopardy. I'll whip Ken's butt as long as they ask about valve stems.

A buddy in the USAF said they had some sort of stick they put against the tires or maybe it was the bearing area after landing. If it melted - too hot. Sound familiar or am I recalling that wrong? (worked with him in the 70s so that's a long time to remember details)

Probably not a Jeep Gladiator risk, but I have ruined tires using decorative caps. Once on a car, once a motorcycle. At sustained high speed the (centrifugal?) force of a heavier cap tears the stem off of the tire.

Wow, 10 demerits for using 'sustained high speed' in the same post as 'Gladiator'.
It's sort of like "Senate Intelligence"

I bought a bunch of bike tubes from Slime for my kids bikes. They came with neon green caps. I've got those on the Jeep now because it's easy to find them if I drop them or put them down somewhere and don't pay attention to where I put them. Ha.

Well, what's considered sustained high speed these days? I've driven at least as fast as those guys spend my money.
You've gone warp 9??
