Because when the temperature goes down, pressure also goes down. Most likely your other tires were already low initially.
Gotcha. But I shouldn’t be worried at all unless it keeps showing low? The tire pressure light did just turn off.
@Nathaniel_Richards
When the tires warm and the temperatures stabilize, fill them up to about 2-3 psi over the door sticker and you should be fine for the rest of winter.

Awesome, thank you for the advice.
@Nathaniel_Richards
No problem.
1 psi drop for roughly every 10 degrees in temp. They’ll come up 1-3 psi when driving a bit.

Great to hear, thanks. The pressure light actually has come off since I drove around a little bit.
Cold weather, happened to me last week, got 27 psi on every tire.
Temperature change; my car does this all the time when it gets cold lol.

Thank you. That was my first thought but wanted to double-check with others since I’ve never noticed it last winter. Thanks though, glad to know it should be fine. Also, the light did turn off once I drove a little bit. Tires maybe heated up haha.
@Nathaniel_Richards
Yep, it’ll do that lol.
Drive it, and it may update.

Hi yes, thanks the pressure warning is gone now haha.

Thanks, you too.
The pressure can change 1 psi for every 10 degrees Fahrenheit. The temperature of your surroundings can cause the air to condense or expand, in turn, changing your tire pressure. Consider adding a few more psi than recommended to keep up with cold weather conditions. Check your tire pressure with an external gauge and you will be fine.

Hi, so when I go to the machine at the gas station and it beeps at me when it hits 33, you’re saying to keep going till it says maybe 35?

Yes. This way if it gets colder, your psi will not be much of an issue until the weather gets warmer. The TPMS sensors aren’t always reliable either, so check your pressures with a gauge.
@MissNicklaus
Gotcha, thank you.
Cold… And the TPMS sensors on these things are pretty bad, I don’t trust them for exact readings or timely updates (seen them not update for over 10 minutes sometimes), a quality physical gauge often shows different results which sometimes will update over time.
But yeah, cold makes a massive difference… why only 3? Who knows, maybe that tire was in the sun or being hit by a reflection, causing it to now be so cold… but it’s likely a result of the cold, use a physical gauge and get them up to 35 psi (or whatever is indicated on the sticker on the driver’s door jamb).
