TPMS Reset

[Iceman25c]

Hello,
I recently had a tire warning come on for low pressure. The tire was measuring 26 psi and I brought it back to 32. The TPMS system now shows it correctly at 32 psi, but the low pressure warning hasn't went off. It's been showing the correct pressure for 4-5 days and about 100 miles of driving, yet still get the warning.

Is there a manual reset or calibration? I've checked the manuals and can't find anything.

I maybe wrong but isn't 32 psi to start with a bit low? For 19" I think the recommendation on RWD is 36 fronts & 38 rears. I run 38 & 40 psi. I'm not sure of the correct pressures on 18"

I don't think any of the Stingers have a 32 psi setting for the tires, I think the lowest is 36 for both the 18" and 19" setup. Check the placard on your door jamb or the manual for the correct pressure for your tires.

Yep, that's it. I just refilled to the point where the other tires were showing, 32 psi instead of checking. 32 wasn't enough to set off the warning for the other tires, but too low to reset the warning. Lesson learned!!

I just realized my tires came from the dealer at 48 PSI. I used a handheld gauge to deflate to 38/36 front to rear but the TPMS still shows 43 PSI. Any thoughts on why?

Did you do this prior to driving the car? The tire pressure should be checked when cold. After some driving the tire pressure goes up 3 psi in addition, for ever 10 degree in temperature increase, it also goes up 1 psi.

Yup. Cold tires per instructions inside the door

Yes, I did post a similar post many months ago to the same question as my car arrived last December with 50 psi all round. I was told that in the factory in Korea they put 50 psi for the travel time across the ocean and the potential extended time in a holding yard or at the dealers. Problem being the cars are selling reasonably quickly and there has been no pressure drop.

This is normal, that’s why you check & set tyre pressure when cold as stated by @GronkSoyFiesta.

You're mostly right here, the higher pressure is for shipping purposes, the only thing your're missing is that the pressure isn't supposed to regulate on its own over time sitting on the lot, the dealerships are supposed to set the tire pressures correctly during the Pre-Delivery Inspection or PDI before you take delivery and some are missing that step.
