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 often should I check my tire pressure?
Dailycarcurator
It's recommended to check your tire pressure at least once a month and before any long trips. Since temperature fluctuations can significantly affect pressure, checking more frequently during seasonal changes is a good practice.
