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 do I choose a portable tire inflator for my car?

Consider the types of vehicles you'll use it on (cars, SUVs, bikes) and the typical tire sizes. Look for models with clear pressure readouts, a long enough power cord or hose, and positive user reviews regarding reliability.
