Tires are integral auto components, as they support a vehicle's weight, apply braking forces to the road, and change the direction of travel. They require the appropriate amount of air to function properly, and since cold weather may affect this, it's important that you know how to prevent problems. Learn more about the connection between cooler outdoor temperatures and air pressure in the guide below.

Do Tires Lose Pressure in Winter?

Tires may lose about one pound per square inch (psi) for every 10-degree decrease in outdoor temperatures. This happens when cold conditions cause air molecules to pack tightly together, which creates empty space within the wheels. Normal wear and tear caused by routine driving may lead to additional pressure loss and even lower air levels during winter.

What Complications Does Low Pressure Cause?

Low pressure can cause the vehicle's weight to bear down more heavily on the wheels and put excess pressure on the rubber. This may cause the tread, which is the part of the wheel that makes contact with the road, to separate or wear rapidly. Since tread increases traction and helps the wheels grip the road, your vehicle may skid, slide, or hydroplane when this part of the tire deteriorates prematurely. This can increase the risk of losing control of the vehicle and getting into an accident.

Excess weight, pressure, and wear resulting from under-inflation may also cause holes and tears to form in the rubber. This may allow air to leak out, resulting in a flat. Additionally, these damages can make tires more susceptible to blowing out, especially if you roll over a pothole or curb. This may cause you to become stranded or potentially lose control and collide with another vehicle.   

Lack of adequate tread caused by low air pressure can increase resistance as the wheels roll over the pavement. This may cause the engine to work harder and use excess gas to propel your automobile forward, leading to poor fuel economy. You notice the need to refill your tank more often, resulting in increased fuel expenses. 

How Can I Check the Pressure?

You can keep your tires properly inflated by checking the pressure about twice a month throughout the winter. A manual or digital gauge will provide accurate psi readings. Simply attach the gauge to the stem of each tire, and compare the number to the recommended psi in your owner's manual. If necessary, add air at the filling station, then re-check the pressure to make sure you've added enough. If you add too much, attach the opposite end of the gauge to the stem to release air before checking the psi again.
