When Should You Check Your Tire Pressure?

Once a Month: Tires naturally lose air over time, even if there are no leaks. A monthly check helps maintain optimal pressure.

Before Long Trips: Planning a road trip? Checking tire pressure beforehand ensures better fuel efficiency and prevents potential blowouts on the highway.

During Temperature Changes: As the temperature drops, so does tire pressure. For every 10°C (18°F) decrease in temperature, your tires lose approximately 1-2 PSI. So, those chilly mornings might be deflating more than just your mood.

When Tires Look Low: If your tires appear flat or saggy, don’t ignore it. However, visual checks aren’t always accurate, so follow up with a pressure gauge.

After a Warning Light: If your car has a Tire Pressure Monitoring System (TPMS) and the light comes on, check your tires immediately.

How to Check Your Tire Pressure

Get a Reliable Tire Pressure Gauge: You can choose between a manual (pencil-style) gauge or a digital one. Many gas stations also provide built-in gauges on their air pumps.

Know the Recommended PSI: Your car manufacturer specifies the correct tire pressure, usually listed in the owner’s manual or on a sticker inside the driver’s side door frame. Note: This is NOT the number on the tire sidewall—that’s the maximum pressure, not the recommended one.

Measure When Tires Are Cold: Check pressure when the tires are cold, ideally in the morning or after the car has been parked for at least three hours. Driving warms up the tires, causing the air inside to expand and giving an inaccurate reading.

Remove the Valve Cap: Unscrew the small cap on the valve stem. Don’t lose it!

Use the Pressure Gauge: Place the gauge firmly on the valve stem until you hear a brief hiss of air. The gauge will display the pressure reading.

Adjust as Needed: If the pressure is too low, add air using a pump (most gas stations have them). If it’s too high, release air by pressing the pin inside the valve stem. Recheck the pressure to ensure accuracy.

Replace the Valve Cap: Screw it back on to keep dirt and moisture out of the valve.

Why Tire Pressure Matters

Improved Fuel Efficiency: Underinflated tires increase rolling resistance, meaning your engine has to work harder and burns more fuel. Proper inflation can improve your fuel economy by up to 3%.

Enhanced Safety: Incorrect tire pressure affects your car’s handling, braking, and overall stability. Underinflated tires are more prone to blowouts, while overinflated ones can reduce traction.

Longer Tire Life: Proper inflation ensures even wear, preventing premature tire replacement. Unevenly worn tires can compromise performance and cost you money in the long run.

Better Performance: Correctly inflated tires provide optimal traction and stability, ensuring a smoother and safer ride.

Pro Tips for Tire Maintenance

Don’t Forget the Spare: Your spare tire is your backup plan, but it’s useless if it’s flat. Check its pressure periodically.

Invest in a Portable Air Compressor: A small, portable air pump can be a lifesaver, especially if you find yourself with low pressure away from a gas station.

Inspect for Damage: While checking pressure, look for signs of wear, cuts, or bulges. These could indicate bigger issues requiring professional attention.

Keep Records: Regularly checking and maintaining tire pressure? Write it down. This helps track trends and detect slow leaks.

Checking your tire pressure might not be the most exciting task, but it’s a simple habit that pays off in fuel savings, improved safety, and longer-lasting tires. So, grab that pressure gauge, and show your tires some love. Your car (and wallet) will thank you.
