How To Tell If Your Tire Pressure Is Low

Are my tires properly inflated? Paul's Auto Services Vehicle Repair from paulsauto.ca

Proper tire pressure is essential for safe driving, fuel efficiency, and tire longevity. However, it can be challenging to tell if your tires are underinflated, especially if you don't have a tire pressure monitoring system (TPMS) in your vehicle. In this article, we'll discuss the signs and symptoms of low tire pressure and how to check your tire pressure accurately.

Signs and Symptoms of Low Tire Pressure

Driving with underinflated tires is dangerous because it can lead to tire failure, decreased handling, and increased braking distance. Here are some signs and symptoms of low tire pressure to watch out for:

1. Poor Handling and Steering Response

One of the most noticeable signs of low tire pressure is poor handling and steering response. Your vehicle may feel sluggish or unresponsive when you turn the steering wheel. This is because underinflated tires have less contact with the road, leading to decreased traction and grip.

2. Reduced Fuel Efficiency

Low tire pressure can also affect your fuel efficiency, causing you to spend more money at the gas pump. When your tires are underinflated, they create more rolling resistance, which requires more energy to move your vehicle forward. This can decrease your fuel efficiency by up to 3%.

3. Abnormal Tire Wear

If your tires are underinflated, they may wear unevenly, which can lead to premature tire failure. Look for signs of abnormal wear, such as cupping, feathering, or scalloping on the tire tread. If you notice any of these signs, it's time to get your tires checked.

How to Check Your Tire Pressure

Checking your tire pressure is a simple task that you can do at home or at a gas station. Here's how to do it:

1. Get a Tire Pressure Gauge

You'll need a tire pressure gauge to check your tire pressure accurately. You can purchase one at an auto parts store or online. Make sure to get a gauge that's compatible with your tire valve stem.

2. Locate the Tire Valve Stem

The tire valve stem is a small metal or plastic cap that covers the valve that allows you to inflate and deflate your tires. It's usually located on the outer edge of your wheel.

3. Remove the Valve Cap and Check the Pressure

Remove the valve cap and press the tire pressure gauge onto the valve stem. You'll hear a hissing sound as air escapes from the tire and enters the gauge. Hold the gauge steady for a few seconds until the hissing sound stops, then remove it from the valve stem.

4. Compare the Pressure to the Recommended PSI

Check your vehicle owner's manual or the tire placard located on the driver's side door jamb to find the recommended tire pressure for your vehicle. Compare the pressure reading on the gauge to the recommended PSI. If the pressure is too low, inflate the tire to the recommended PSI. If it's too high, release some air until it reaches the recommended level.

Conclusion

Driving with underinflated tires is a safety hazard that can lead to tire failure, decreased handling, and reduced fuel efficiency. By knowing the signs and symptoms of low tire pressure and how to check your tire pressure accurately, you can ensure that your tires are properly inflated and safe for the road ahead.
