Maintaining the correct tire pressure is essential for safety, fuel efficiency, and tire longevity. Properly inflated tires ensure even wear, improve handling, and maximize fuel efficiency. Underinflated tires can lead to poor performance and a higher risk of blowouts, while overinflated tires may cause uneven wear and a harsher ride.

When to Check Tire Pressure

For the most accurate reading, check your tire pressure when the tires are cold—ideally after the car has been parked for at least three hours. Driving heats the tires, causing the pressure to rise, which can lead to inaccurate readings.

Finding the Correct Tire Pressure

Your vehicle’s recommended tire pressure is measured in pounds per square inch (PSI) and can be found in several places:

• Owner’s Manual: Provides the manufacturer’s recommended PSI.
• Driver’s Side Door Jamb: A sticker inside the door frame lists the correct PSI.
• Tire Sidewall: Displays maximum PSI.

Although you can use the sidewall of your tire, it’s important to consult your owner’s manual or the tire placard on the driver’s side door jamb for more accurate information.

How to Check Tire Pressure

1. Use a Tire Pressure Gauge: Essential for an accurate reading.
2. Remove the Valve Stem Cap: Unscrew the cap from the tire’s valve stem.
3. Press the Gauge Firmly: Ensure there’s no hissing sound.
4. Read the PSI: Note the displayed pressure.
5. Repeat for All Tires: Verify each tire is within the recommended range.

Adjusting Tire Pressure

• If PSI is Low: Add air using an air compressor until reaching the correct level.
• If PSI is High: Release air by pressing the valve stem gently.

How Often to Check

It’s advisable to check your tire pressure monthly and especially before long trips. Changes in temperature, load, and altitude can significantly affect tire pressure:

• Temperature: Cold air reduces pressure, while warm air increases it.
• Load: Heavier loads may require higher PSI.
• Altitude: Higher altitudes can lower pressure.

Tire Pressure Warning Light

Modern vehicles are equipped with Tire Pressure Monitoring Systems (TPMS). If your warning light comes on:

1. Pull Over Safely: Stop in a secure location.
2. Check the PSI: Use a tire gauge to measure each tire.
3. Adjust Air Levels: Add or release air as needed.
4. Consult a Mechanic: If the light stays on, it could indicate a TPMS issue or a slow leak.

Regular Maintenance Tips

• Check Tire Pressure Monthly: Inspect tire pressure at least once a month and before long trips.
• Use Built-in Vehicle Displays: Some vehicles show individual tire pressures on the dashboard, making monitoring easier. If your car doesn’t have this feature, a manual check is essential. Note that some vehicles require the TPMS system to be put in reset mode, while others reset automatically while driving.

Maintaining proper tire pressure is simple but vital for your vehicle’s performance and safety. Regular checks can save fuel and extend tire life. Have questions or need help? If you have questions or need assistance, schedule your appointment with Burt Brothers today—our team is here to help!
