Many drivers face a similar dilemma when outdoor temperatures start to drop: The tire pressure lights on their cars come on, signaling issues with the tires. But is there really a problem that needs addressing? How serious is it, and will it require a tire replacement? Or…is an illuminated tire pressure light just a natural consequence of cold weather? Below are answers to these questions in a discussion of the relationship between exterior temperatures and tire pressure.

Cold Weather Reduces Tire Pressure

The reason the tire pressure light comes on is because cold temperatures can cause a notable reduction in tire pressure. The sensors in modern-day vehicles are extremely sensitive to even slight changes in the various levels of pressure and fluids that are needed to keep the vehicle working its best. After relatively mild weather, a cold snap causes air in the tire to contract, lowering the pressure, and setting off the sensor, which in turn, activates the light on your dashboard.

What to Do

While lowered tire pressure is a natural consequence of cold weather, it shouldn't be ignored. You likely won't need a tire replacement or any costly fixes, so long as you act promptly. There are many dangers that come with driving on underinflated tires, including the tire overheating, premature wear and tear, tread separation, and blowouts.

Whenever the tire pressure light comes on, use a gauge to get a reading on each tire and determine which one is low. Then, add air until that tire has returned to an acceptable level of inflation. Many people choose to have this performed by an auto repair professional and checking tire pressure is typically a part of the routine car maintenance performed by mechanics. A professional can also deduce whether a more serious issue is present and alert you to the need for a tire replacement.

While there's generally no need to panic when you see a tire pressure light illuminate, it's important to check the tires to ensure everything is in proper working order.
