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.
Where can I find the correct cold tire PSI for my car?
The recommended cold tire inflation pressure, often called PSI (pounds per square inch), is usually found on a sticker located on the driver's side doorjamb or in your vehicle's owner's manual. Do not use the pressure listed on the tire sidewall, as that is the maximum pressure the tire can hold.
