Winter weather puts stress on your tires in several ways. Not only are they subject to icy and snowy road conditions, but they also deflate more readily with the weather is cold. Learn why this is and what you can do about it to stay safe on the road this winter and avoid premature tire changes.

Why Do Tires Go Flat  in the Winter & What Can I Do About It?

A Drop in Pressure

While hot weather increases tire pressure, cold temperatures cause it to drop. Air molecules move at a slower rate during frigid weather, resulting in denser, lower-pressure air. For every 10 degrees the temperature decreases, your tires lose one to two pounds per square inch (psi). As your tires deflate from this pressure change, they make more contact with the road, causing friction and overheating issues. Excessive friction wears tires out quickly, increasing their susceptibility to tread separations and punctures. Blowouts from underinflated tires are even more dangerous during winter because icy roads make it harder to control your vehicle.

Rubber & Rim Separations

Cold temperatures also affect tires due to contraction issues. Tires stiffen in response to cold weather, which loosens the seal between the rim and the rubber. This creates space and subsequently slow air leaks that often go unnoticed until the auto part is completely flat. Aluminum alloy wheels are especially susceptible to this problem because the metal does not create effective seals and can corrode from road salt and other debris. Corrosion creates small gaps between the tire and wheel that allow air to escape.

Routine Checks

Protect your wallet from untimely tire changes by checking the pressure monthly. Use an inexpensive pressure gauge tool to determine air loss so you can top them off accordingly. Remember that overinflated tires also decrease vehicle safety, so make certain you fill yours per your car manufacturer’s recommendations. Also, consider keeping your vehicle in a heated garage to limit rubber/rim separation issues.
