Answer from Dailycarcurator
Cold weather causes tire pressure to drop, which can trigger your car's Tire Pressure Monitoring System (TPMS) light.
Tires lose about 1 PSI for every 10-degree Fahrenheit drop in temperature. When the air inside your tires cools, it contracts, leading to lower pressure. If this drop causes the pressure to fall below the minimum threshold set by your vehicle's TPMS, the warning light will illuminate.
This information is for general guidance; always consult your vehicle's owner's manual for specific recommendations.
How do I use a tire pressure gauge?

Ensure your tires are cold. Remove the valve cap from one tire, press the gauge firmly onto the valve stem until the hissing stops, and read the pressure displayed. Replace the valve cap immediately after checking.
