Stupid TPMS!!
The new GM 1500s must have a lower threshold now! Just rotated the tires on my 2020 1500 Chebbie and set the rears (which are still reading front position and may be the issue but requires a re-learn tool to change) to 32psi cold. Truck is a pavement princess that is mostly driven empty, no load.
My old 2016, I recall didn't trip the low pressure light until > 25psi. I know I could air down for winter driving to under 30psi without getting the light.
At night pressure dropped to 31 psi...BAM, tire light. Up to 34-35psi on the highway, no luck, didn't disappear.
Owners manual, doesn't appear to show the threshold values nor if they're different front to rear.
Oh well, starting to get used to the tire light since the thresholds have been too high on trucks since the whole tpms mandate began.
Just venting...
