Default Accuracy of TPMS?

Tires cold, the dash reads 32psi across the board. However, with a quality, analog tire pressure gauge I'm reading 37psi (door sticker's recommendation).

Has anyone else found material inconsistencies between an analog gauge and the car's TPMS? I'd like to believe the analog is more accurate, but without a second external gauge to cross-check the first I can't say definitively.

Mine is way out, as much as 37 PSI.
Not having TPMS might explain that though.

I guess my analog gauge isn’t as “quality” as I thought... thank you, gentlemen. I’ll be running over it with the tractor tonight.
