How to Check Your PSI Levels

While most modern vehicles come equipped with a Tire Pressure Monitoring System (TPMS), this feature is designed to only alert you when one of your tires PSI levels dips 25% below the manufacturer’s recommended level. This should be used only as a safety device and not a maintenance tool.

Tire Pressure Monitoring SystemShould this light ever appear while on the road, immediately head to the nearest service center or gas station to have each tire inspected. In the meantime, most service professionals recommend checking your tire’s PSI levels at least once per month.

The good news—when you follow these steps, the process is surprisingly simple to perform:

  1. Look Up the Required Tire Pressure. PSI levels vary depending on the size of the tire and type of vehicle you drive. Your owner’s manual can tell you the exact level each of your tires should be inflated. You also can retrieve this information from the inside of your driver’s door well.
  2. Use a Digital Tire Gauge. While traditional gauges are helpful in a pinch, it’s recommended you use a digital gauge to ensure accuracy. Remember, every 1 drop in PSI can lower your MPG by as much as 0.2%. This can quickly start to add up if ignored for long enough.
  3. Unscrew the Valve Cap. Press the digital gauge making sure the nozzle and pin are securely fastened. It should only take a few seconds for the gauge to retrieve a reading. Return the valve cap to the nozzle and repeat this step with each tire.
  4. Fill the Tire with Air. Using a tire pump, fill each tire to the recommended PSI level while paying close attention so you don’t overinflate the tire.

If you accidentally add too much air to the tire, simply press the back of the gauge onto the air valve to release the extra pressure. Over inflated tires round out the tread section causing the center to prematurely wear down.

Why is Checking Your Tire’s PSI Level Important?

Tire’s PSI Level is ImportantA properly inflated tire is designed to firmly grip the roadway so you can confidently steer and brake without issue. Tires are carefully designed to have a certain level of tread touching the road. If your tires are underinflated, more rubber is contacting the road surface which causes friction.

This friction damages the tire while potentially causing additional issues like:

  • Brake and alignment issues
  • Engine wear
  • Tire leaks and blowouts
