It’s that time of year again in the Midwest. As temperatures fluctuate warm and cold and we get glimpses of spring one day with snow the next, your tire pressure can be a little out of control. Ensuring your tire pressure is correct is very important to the overall health of your vehicle. Here’s what you need to know to make sure your PSI is stable and ready for whatever weather comes our way.
Why Tire Pressure Changes in Cold Weather
Tire pressure naturally fluctuates with temperature. For every 10-degree drop in outside temperature, tire pressure can decrease by about 1 PSI. In the Midwest, where one week can feel like winter and the next like spring, these swings happen often and sometimes overnight. That means a tire that was properly inflated yesterday could be underinflated today.
Underinflated tires don’t just trigger that dashboard warning light; they can affect braking, handling, fuel efficiency, and overall tire lifespan too.
The Risks of Driving on Improperly Inflated Tires
When tire pressure is too low, more of the tire’s surface contacts the road. This increases friction and heat buildup, leading to faster wear and reduced fuel economy. Low pressure can also make steering feel sluggish and increase stopping distance, which is especially dangerous on wet or icy roads.
Overinflated tires aren’t ideal either. Too much air reduces traction and can cause uneven wear, making it harder to maintain control during sudden stops or sharp turns.
How to Check Your Tire Pressure Correctly
To get an accurate reading, always check tire pressure when your tires are “cold,” meaning the vehicle hasn’t been driven for at least a few hours. Use a reliable tire pressure gauge and compare the reading to your vehicle manufacturer’s recommended PSI, not the number printed on the tire itself. You can usually find the correct PSI on a sticker inside the driver’s door or in your owner’s manual. During winter and early spring, check tire pressure at least once a month and anytime you notice a sudden change in temperature.
Don’t Ignore the TPMS Light
Your Tire Pressure Monitoring System (TPMS) is designed to alert you when pressure drops below a safe level. Cold weather is one of the most common reasons this light comes on. While it may turn off once temperatures warm up, that doesn’t always mean the issue has resolved. Treat the light as a reminder to manually check your tires and adjust as needed.
Keep Your Tires Winter-Ready
In addition to monitoring PSI, make sure your tires are in good overall condition. Check for uneven tread wear, visible cracks, or bulges, which can become more problematic in colder weather. Proper inflation combined with routine inspections helps your tires handle Midwestern road conditions more safely and efficiently.
