So cold...

So cold...
Back from my trip to the outlaws ... Started out early morning -27 windchill -6 degree with 50mph gusts of winds , got in the car and DING DING DING "Check tire pressure" ???WHAT ??? so I scroll through and showing low pressure on all 4 tires 27-30psi ( in pairs ) so I get out to look and all look fine. Drove down and checked as driving...stayed the same. Today it warmed up to 50 and windy, still showing low psi but all are 30psi? tomorrow should be warmer as well so Ill pop the compressor on all and get them inflated where they should be if needed, Im just thinking the cold is just messing with the sensors in the tires?

You add air when cold to bring up pressure and let air out when warm to lower to correct pressure.
An average wheel at 32 psi and 100 degrees will drop to 24 or 25 at 0 degrees and visa versa.

It's just simple chemistry. Pressure and temperature are directly correlated.

I don't like my teeth rattling or rollover danger or excessive center tire wear or tires popping off.
Just look at the TPM occasionally and look for free air. If you are aware of a phenomena you have warning. Just like "blind spots"; no such thing if you know about them.

Thought I posted an update a few days ago but dont see it? I checked the air pressure since it warmed up outside and the tire pressures are good at 30 psi which also shows the same on the board....guess the sensors are just anal to the cold? They are all brand new along with the tires only a few months old.

And I guess you didn't read any of the responses.
NOTHING to do with wonky sensors. Just science; air volume decreases with temperature, less volume in a defined space equals lower pressure.
If you were to drive on tires with low pressure the flexing of the sidewalls will heat the air which increases the volume and pressure. So, say you let air out of the tires to 26 PSI then go for a drive the air pressure will increase to (probably) over 32psi. If you keep them at the recommended pressure they will stay pretty close. If you fill them with an inert gas they will stay pretty much the same no matter the temperature.
