Drivers often see an uptick in tire pressure monitoring system (TPMS) warnings during the cold season, even in coastal Alabama. A lot of car owners are probably at a loss as to why the pressure light keeps activating and wondering whether they're due for a visit to their mechanic for car maintenance. Here's a rundown on what this pressure light means and why you should never ignore it.

Why Your Tire Pressure Light Activates in Cold Weather

The TPMS is designed to warn you when your tire's recommended inflation pressure changes. When this happens, a horseshoe-shaped icon with an exclamation point in the middle lights up in the dashboard.

Car maintenance experts explain that your car's tire pressure decreases by 1 to 2 PSI for every 10-degree drop in temperature. This is because cold weather shrinks molecules while heat causes it to expand. In this situation, the low temperature causes the volume of air to shrink. Less air means less filled tires.

What Are the Dangers of Underinflated Tires?

Tires have to be kept at a specific pressure for optimal performance. Driving on underinflated tires can lead to performance issues and could put everyone on the road in danger. According to the National Highway Traffic Safety Administration, cars with tires that are more than 25 percent underinflated are three times more at risk to be involved in crashes.

One reason could be overheating. The decrease in tire pressure can result in overheated tires, which then leads to tire wear and poor handling. It also increases the danger of a blowout.

Underinflation also reduces a tire's life span. A tire that's underinflated by eight PSI can see a reduction of 15,000 km in tire life. Your car will also see a drop in fuel efficiency, which means you'll be spending more money on gas until you bring it in for car maintenance.
