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 kind of tire pressure gauge should I use?
Dailycarcurator
A digital tire pressure gauge is generally recommended for its accuracy and ease of reading. Pencil-style gauges are also common and affordable, but ensure you get a reliable one. Always check the gauge's accuracy periodically.
