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.
Should I worry if my TPMS light is on during a cold morning?
It's a sign that your tire pressure is low due to the cold. While it might go off as you drive, it indicates your tires are underinflated. It's best to check and adjust the pressure to the recommended level to ensure safety and optimal tire wear.
