2021 here and temps hit -10 the other night dropping my psi to 30 all the way around. No light yet.

Will never be an exact PSI but most TPMS will trigger at +/- 10% of posted door placard.

2020 Rubi here, Sunday night -14 temp dropped my pressure to 29 psi and triggered a light. Worst of it was that this time of year all to gas stations remove the outside air hoses until spring; had to drive home w/light on. My mini compressor is now part of my winter gear.
