What Should My Tire Pressure Be & How Often Should I Check It?

Why Tire Pressure Matters

Proper tire pressure is one of the simplest — yet most overlooked — aspects of car maintenance. Driving with underinflated tires reduces fuel efficiency, increases wear, and makes handling less stable on wet or icy roads. Overinflation, on the other hand, causes a harsher ride and uneven tread wear.

Keeping your tires properly inflated ensures better grip, longer lifespan, and safer driving — especially during seasonal changes when temperatures affect PSI levels dramatically.

What Should My Tire Pressure Be?

Most vehicles require a tire pressure between 30–35 PSI (pounds per square inch), but it’s always best to follow your manufacturer’s recommendation.
You can find the correct PSI listed:

• On a sticker inside the driver’s door jamb

• In your owner’s manual

• Or on the fuel door

Always check tire pressure when the tires are cold, ideally before driving or after the car has been parked for several hours. This gives the most accurate reading since driving warms the tires and raises internal air pressure.

How Often Should You Check Tire Pressure?

For most drivers, checking tire pressure at least once a month is a smart habit. However, tire pressure isn’t a “set it and forget it” number — it fluctuates with temperature changes, road conditions, and driving habits. Understanding how weather affects your tires helps you stay safer and extend their lifespan year-round.

Tire Pressure in Cold Weather

In winter, your tires lose air faster than you might think. On average, pressure drops about 1 PSI for every 10°F decrease in temperature, which means a chilly morning can make perfectly filled tires appear underinflated. Underinflated tires reduce traction on snow and ice, increase braking distance, and wear unevenly — all of which can compromise safety.
That’s why during colder months, it’s best to check your tire pressure every two weeks, or anytime the temperature swings drastically overnight.

Tire Pressure in Warm Weather

In summer, heat causes the air inside your tires to expand, raising PSI levels. Overinflated tires can lead to a rougher ride and reduced contact with the road, especially during long highway drives. Check your tire pressure regularly on hot days, especially before long trips, to prevent uneven wear or blowouts.

All-Season Pressure Care

Whether it’s cold winter mornings or scorching summer afternoons, maintaining consistent tire pressure is essential. Always check your PSI when your tires are cold (before driving), and adjust according to your manufacturer’s recommendation — not the number on the tire sidewall.

Regular checks prevent small leaks or seasonal shifts from turning into dangerous underinflation issues. Using a digital tire gauge or a wireless monitoring system like SolarTire Alert™ can help you track changes in real time and maintain perfect balance through every season.
