How to Check Your Tire Pressure | Heart Auto Care

According to the National Highway Transportation Safety Agency’s data, a tire that is underinflated by 25% triples the likelihood of being involved in an accident. Conversely, overinflating a tire by 25% doubles the risk compared to a tire with correct pressure.

Proper tire pressure is a crucial aspect of car maintenance that often goes unnoticed. Yet, it’s essential for safe driving and optimal fuel efficiency. This guide will walk you through the simple process of checking your tire pressure. Let’s dive into the steps and understand why this routine check is so important for your vehicle’s performance and longevity.

When and How Often Should You Check Tire Pressure?

The question of when and how often to check your tire pressure is critical. It’s suggested to examine your tire pressure at least once a month, or even better, form a habit of doing so each time you pause to fill up your car’s gas tank. However, this frequency can vary depending on factors such as weather conditions and driving habits.

For instance, in colder seasons, tires tend to lose pressure more quickly. So, it might be necessary to check your tire pressure more frequently during winter. Similarly, if you are in the habit of driving long distances or at high speeds regularly, it would be prudent to check your tire pressure more often.

8 Steps to Check Tire Pressure

Now that you know the importance and frequency of checking tire pressure, let’s delve into the step-by-step process of doing so.

Step 1: Park Your Vehicle

First things first, park your vehicle on a flat surface to ensure accurate readings. Remember, the tires should be ‘cold’ when you check the pressure. By ‘cold’, we mean that the vehicle should not have been driven for at least three hours. This allows the tires to cool down and the air inside them to settle, providing a more accurate reading.

Step 2: Locate the Recommended Tire Pressure

The recommended tire pressure for your vehicle can usually be found in the owner’s manual. If not there, you can also look for it on the driver’s side door jamb, in the glove box, or inside the fuel hatch. The recommended pressure is typically given in pounds per square inch (PSI).

Remember, different vehicles will have different recommended tire pressures. Even within the same vehicle, the front and rear tires may require different pressure levels. Always refer to your vehicle’s manual or the manufacturer’s sticker for the correct information.

Step 3: Remove the Valve Cap

The valve cap is the small cover that you see on the tire’s valve stem. To remove it, simply turn it counterclockwise until it comes off. Keep it in a safe place as you’ll need to replace it after checking the tire pressure.

Step 4: Use the Tire Pressure Gauge

To check the tire pressure, you will need a tire pressure gauge. There are different types of gauges available, including stick-type, digital, and dial gauges. Regardless of the type, the process of using them is similar.

Place the end of the gauge onto the valve stem and press down hard enough to hear a hiss sound. This sound indicates that air is escaping from the tire through the gauge and the pressure is being read.

That’s where we’ll pause for now. Stay tuned for the rest of the steps in this essential guide on how to check your tire pressure.

Step 5: Read the Tire Pressure

Once you’ve pressed down on the gauge, it will give you a reading. If you’re using a stick-type gauge, the stick that pops out from the bottom will show you the pressure. Digital and dial gauges will display the pressure on their screens or dials, respectively.

Step 6: Add Air if Needed

If the reading is below the recommended PSI, your tire needs more air. To add air, simply press the air hose onto the valve stem just like you did with the gauge and fill for a few seconds at a time. After each fill, use your gauge to check the pressure again. Repeat this process until your tires reach the recommended pressure.

Step 7: Recheck All Tires

After you’ve finished with one tire, move on to the next. Remember to replace the valve cap before moving on. It’s important to check all four tires as they may not all lose air at the same rate.

Step 8: Reinstall Valve Caps

Once you’ve checked all tires and filled them to the recommended PSI, don’t forget to replace the valve caps. These caps protect the valve stems from dirt and moisture, so it’s essential to put them back on.

The Importance of Regularly Checking Tire Pressure

Regularly checking your tire pressure is a crucial aspect of vehicle maintenance that often gets overlooked. Not only does it contribute to safer driving, but it also enhances the efficiency and longevity of your tires.

  • Safety: Incorrect tire pressure can lead to poor traction, reduced control over the vehicle, and even tire blowouts. Regular checks can help prevent these dangerous situations.

  • Fuel Efficiency: Properly inflated tires can improve gas mileage by up to 3%, reducing both your fuel costs and environmental impact.

  • Longevity of Tires: Under-inflated or over-inflated tires wear out more quickly and unevenly. Regular pressure checks can extend the life of your tires, saving you money in the long run.

  • Performance: Optimal tire pressure contributes to better vehicle handling and performance, offering a smoother and more enjoyable driving experience.

Regularly checking your tire pressure is a simple yet effective way to enhance your vehicle’s safety, performance, and efficiency. It takes just a few minutes each time you fill up your gas tank, but the benefits are substantial and long-lasting. So, make it a habit – your vehicle, your wallet, and potentially your life could depend on it.
