Under Pressure…Keeping Your Tires Inflated Will Make Them Last Longer and Your Vehicle Will Use Less Fuel Too!

Posted on: by

Even if you have a Tire Pressure Monitoring System (TPMS), as equipped on many newer vehicles, you should check your tire pressures regularly, at least monthly. Most tires lose one pound per square inch (PSI) per month, assuming the temperature does not fluctuate much. If temperatures drop, tire pressures also drop. Every 10 degrees Fahrenheit (°F) drop in temperature causes tires to lose 1°F.

Underinflated tires increase friction against the pavement and can cause excess tire wear, even blowouts when the vehicle is fully loaded or overloaded. You cannot tell the appropriate tire pressure by just looking at the sidewall of the tires and estimating how flat it looks against the pavement. Tires have various sidewall flex characteristics based on their aspect ratio (section height divided by width), traction rating (e.g., A, B, C) and intended use, so use a quality tire gauge to check your tire pressure against specifications.

    Totally agree, maintain tire is a must if you have a vehicle

    Interesting stats, I didn’t know it was at 10 degree intervals like that. It would be interesting to see how regular air inflated tires line up against Nitrogen or even….. helium.

    TPMS is what I personally would not trust, the time those sensors alarm your are too late..monitoring them manually is what I suggest with a simple pressure gauge.

    Good basic description for maintaining your car during the year. I wanted to add on the part of keeping an eye on your tire pressure since this under inflated tires do also cause worsened steering behavior causing your car to steer less accurately as well.
    Neglecting to check your tire pressures may also result in uneven and even quicker tire wear.
    I recommend a accurate air tire gauge and a car escape tool equipped with a window hammer to equip in everybody’s car.
