Your tires are the only part of your vehicle that touches the road, making proper tire pressure essential for safe driving. As the seasons change, so do temperatures and road conditions, which can have a direct impact on your tires. Ignoring these seasonal changes may lead to uneven wear, reduced fuel efficiency, and poor handling.
Understanding how each season affects your tires is an important part of tire maintenance. By checking your seasonal tire pressure regularly, you can help your Subaru perform safely and efficiently all year long.
Why Tire Pressure Changes Throughout the Year
Air inside your tires expands when temperatures rise and contracts when temperatures fall. A general rule is that tire pressure changes by about one PSI for every 10-degree change in outside temperature.
Because weather can fluctuate dramatically throughout the year, it's important to check your tire pressure regularly instead of assuming it stays constant.
Driving with tires that are overinflated or underinflated can affect:
-
Vehicle handling
-
Braking performance
-
Tire wear
-
Fuel economy
-
Overall driving comfort
Routine tire maintenance helps prevent these issues before they become larger problems.
Spring: Temperature Swings Can Affect Tire Pressure
Spring often brings unpredictable weather. Cold mornings followed by warm afternoons can cause your tire pressure to fluctuate throughout the day.
During this season, drivers should:
-
Check tire pressure frequently as temperatures change.
-
Inspect tires for damage caused by winter potholes.
-
Look for uneven tread wear after months of cold-weather driving.
Spring is also a great time to schedule a tire inspection and rotation as part of your regular maintenance routine.
Summer: Heat Can Increase Tire Pressure
Hot weather causes the air inside your tires to expand, increasing tire pressure. While properly inflated tires can handle normal summer temperatures, overinflated tires may reduce the amount of tread contacting the road.
Summer driving can also increase tire temperatures due to:
-
Long highway trips
-
Heavy traffic
-
Hot pavement
-
Carrying extra passengers or cargo
Before long vacations, check your pressure using the manufacturer's recommended specifications found on the driver's door jamb rather than the number printed on the tire sidewall.
Regular inspections during the summer also help identify excessive tread wear before it becomes a safety concern.
Fall: Prepare Your Tires for Cooler Weather
Fall is the perfect time to prepare your vehicle for colder temperatures. As the weather begins cooling, tire pressure gradually decreases.
During the fall, consider:
-
Checking tire pressure every few weeks.
-
Inspecting tread depth before winter arrives.
-
Rotating your tires if recommended by your maintenance schedule.
-
Looking for signs of uneven wear.
Completing these simple maintenance tasks helps prepare your vehicle for more challenging winter road conditions.
Winter: Cold Temperatures Lower Tire Pressure
Winter has the greatest impact on tire pressure. Cold air causes the pressure inside your tires to drop, sometimes triggering your Tire Pressure Monitoring System (TPMS) warning light.
Low tire pressure can lead to:
-
Reduced traction on snow and ice
-
Longer stopping distances
-
Faster tread wear
-
Lower fuel efficiency
-
Less responsive steering
Winter road hazards such as potholes can also damage tires and wheels, making regular inspections even more important.
Checking your tire throughout the winter helps your tires perform as intended when road conditions become more difficult.
Tips for Maintaining Proper Tire Pressure Year-Round
Keeping your tires properly inflated doesn't require much time, but it can significantly improve safety and tire life.
Good tire care includes:
-
Checking tire pressure at least once a month.
-
Measuring pressure when the tires are cold.
-
Following the recommended PSI listed on your vehicle.
-
Inspecting tires for cuts, cracks, or uneven wear.
-
Rotating tires according to your maintenance schedule.
These simple habits help extend tire life while improving vehicle performance in every season.
