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.

What does 'cold tire PSI' mean?

Dailycarcurator

'Cold tire PSI' refers to the recommended tire pressure when the vehicle has been sitting for at least three hours or has been driven less than a mile at moderate speed. This is the baseline pressure measurement that accounts for normal temperature variations.
