TPMS Warning, make sense of this?

[LooselyHeldPlans]

Are the thresholds tire dependent?

No. I air down a lot, so I've been through this. It seems like each tire has to reach and maintain 35 psi for a little time, maybe 5 mins, and then it will all reset as "good" (no red) and the warning will go off. Then they can go down to say 32 without triggering it. Did you just air down? Extra cold morning?

Here's a non-helpful reply

Trying to find consistent/predictable outputs for Jeep systems given non-variable input values, is the definition of insanity (for JLs).

This is typical to see... the norm lets say .... no issue to worry about.

In your locale, in the Winter months, you need to keep all 4 on the ground tires inflated to 35# psi or you will have on going issues with psi low warnings..

Now you need to inflate all on the ground tires to 37# and drive for say a mile until the psi warning goes away.... Then wait til tires are cold and deflate all tires to 35#.

Keep at 35# until warmer weather comes and then you can run lower psi.

Yeah, just starting to get cold in Denver.

Factory pressure is 37 and there is a 6 lb threshold in the TPMS system. If it goes below 31, it will give you a warning on that tire until it's inflated back to 37 to turn off the alert. Most of the programmers will let you lower that value.
