Cold weather tyre pressures
I notice this every winter when we drop down to -15C or so. A check all tyre pressures warning comes on. My pressure monitor is normally set to normal loads, in cold conditions if you set it to light loads, the warnings go out.
Just an observation, and a check with a gauge usually confirms all is well, although last night at -20C without wind chill, I couldn't be arsed to use a gauge

It's not the TPMS confused with winter. Air density varies with temperature which means less volume of air inside the tyre with colder temperatures which will translate in less pressure. I run my tyres at the lower end of the "warning signal" (30/33) and if temperature drops TPMS will flag it. -
