TPMS reports "tire pressure higher than recommended value" at 45 PSI

[SandWedge]

Yes! That turned the notice off. Question is why after 4K miles did it change

Just to be clear, your pressure is now 44psi or below and anything over 45psi sets off the warning?

Actually 1 @ 46 and 1 @ 47. No warning notification. I'm going to see exactly where it trips at some point.

Like I said, it might be a software update with a narrow threshold window.
I put 4K miles on the car and never had this happen @ 50PSI. ???

I meant how come you prefer the rock hard rubber? 50psi is a lot!

If yours is at 50 psi, you aren't having the same problem others are having. Theirs are triggering at 45-ish.

From what I can find OEM 19" Gemini tire is the Continental ProContact RX 255/45R19 104W XL T1 which has a max cold psi limit of 51 psi.

Depending on what actual psi number you are seeing, I'm going to guess what changed for you is the temperature during your drive changed. This can push the max measured pressure a bit higher. I presume when you say 50 psi that is your cold pressure (and actual reading you see is higher).

You are basically running at the rated limit of the tire, so it makes sense for it to alert for you. It doesn't make sense for the others as they are significantly under.

My 2024 did this to me the other day. Must be a software update with a narrow window threshold.
I run 50 PSI!

50? Why so high? So that means you are in the 55-56 range when warm (especially given where you live) and potentially wearing the middle of the tread sooner...

Yes, I agree with for others. I just can't figure out why mine changed after 2 months and 4K miles at the same cold tire
setting of 50 PSI
