3 Reasons Your Cold Tires May Be Flat
1. Tires have air pressure inside them. When the temperature drops below freezing, the tire’s internal air pressure decreases. As the air pressure decreases, the tire loses its ability to hold air in the tubes. If the pressure continues to decrease, the tubes may rupture, causing the tire to lose air completely.
2. Cold temperatures cause the rubber to harden. Rubber becomes harder at lower temperatures. When the temperature gets colder than -10 degrees Fahrenheit (-23 degrees Celsius), the rubber begins to stiffen and become brittle. That makes it less likely that the tire will regain its shape after being flattened.
3. Ice forms between the tread and the road surface. The ice prevents friction between the tire and the road. Friction causes heat buildup, which increases the likelihood of tire failure.
