Cold weather affects your vehicle in many ways, from thickened motor oil to a drained battery. Frigid temperatures also cause tire problems without proper maintenance, specifically those related to air pressure. Learn what cold weather does to this pressure to keep your vehicle safe and avoid premature visits to your local tire dealer.

What Does Cold Weather Do to Tire Pressure?

A Drop In PSI

Tire pressure is measured in pounds per square inch, or psi. Air contracts in reaction to cold temperatures, causing the psi to drop. For every 10 degrees the temperature lowers, your tires lose a pound of psi. So, while your tires may be fully inflated during 70-degree Fahrenheit weather, they lose about five pounds of pressure during 20-degree weather. Heat also negatively affects tire pressure because air expands, resulting in overinflation. If you park your car in a heated garage after driving it in the cold all day, your tires undergo several pressure changes.

Why You Need A Pressure Gauge

Tire dealers recommend using an inexpensive pressure gauge tool to check these important vehicle components once a month or more frequently if your region is subject to severe temperature fluctuations. Refer to your owner’s manual and the information found in the driver’s side door jamb for your vehicle model’s correct psi.

The right tire pressure prevents dangerous handling and braking issues from over and underinflation. Overly inflated tires make less contact with the road and therefore cannot provide sufficient traction to prevent skidding and sliding, something especially dangerous when roads are wet or icy. Underinflated tires are just as hazardous because they make too much contact with the road, resulting in premature, uneven wear. Bald tires do not grip the road to increase your accident risk. Using a pressure gauge tool subsequently helps your tires stay at the right pressure for safer days and nights behind the wheel.
