In winter more so than other seasons, it’s essential that you check your tire pressure and inflate them when necessary. Why? We’ll get into that and tell you exactly how you can check your tire pressure on your own.

Cold Weather and Tire Pressure

When the temperature drops to a certain level, the molecules in the air slow down and move closer together. Once the temperature rises again, those same molecules will speed up and move away from one another. When this scenario plays out within your tires, the pressure is affected to some extent. For every five degrees Celcius that the temperature changes, your tires can lose or gain one to two pounds of per square inch or PSI.

Therefore, if your tires sat out in the cold for the weekend and the temperatures dropped by 10 degrees, you’d lose two PSI without doing a thing. Low tire pressure isn’t something that should be ignored, even though the pressure should bounce back as the air warms up. Low tire pressure can result in an increase in your braking time, meaning that your car will skid more easily when travelling on wet roads. Low pressure can also lead to poor fuel efficiency and shorten the lifespan of your tires.

How to Check your Tire Pressure

While you’ll be able to notice when your tires have lost a significant amount of air, smaller decreases won’t be as easy to detect. To check your tire pressure, first look in your vehicle manual and determine what the recommended pressure should be. The recommended PSI is around 30-35, but double check with your vehicle model to be sure. For the most accurate reading, check the pressure before driving.

When you’re ready, take out your tire pressure gauge, which can be purchased at most retailers. Moving to your tire, unscrew the valve stem cap on the tire, which is usually a black or silver screw on the tire’s rim. Attach the gauge to the stem. Hear a hissing noise? Then the gauge isn’t aligned properly. Readjust until the hissing stops and note the tire pressure reading before repeating this process on your other tires. If the readings are lower than the recommended PSI, then you know it’s time to fill them with air to ensure the best drive quality.
