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 much does tire pressure drop in cold weather?
Dailycarcurator
Tire pressure typically drops by about 1 PSI for every 10 degrees Fahrenheit the temperature falls. For example, if the temperature drops 30 degrees, you might see a 3 PSI decrease in your tires.
