How to Check Nitrogen Tire Pressure (A Comprehensive Guide)

How to Check Nitrogen Tire Pressure

Why Checking Nitrogen Tire Pressure is Important?

Proper tire pressure is crucial for ensuring your vehicle’s safety and performance on the road. One way to maintain optimal tire pressure is by using nitrogen instead of regular air. Nitrogen-filled tires offer numerous benefits, including improved fuel efficiency, longer tire life, and better handling.

However, just like regular air-filled tires, nitrogen-filled tires also require regular pressure checks to ensure they are properly inflated. In this article, we will guide you through the process of checking nitrogen tire pressure to help you maintain the safety and performance of your vehicle.

Tools Needed for Checking Nitrogen Tire Pressure

Before we dive into the steps of checking nitrogen tire pressure, let’s first gather the necessary tools. Here’s what you’ll need:

  • Tire pressure gauge: This tool is used to measure the air pressure inside the tire.
  • Air compressor: If the tire pressure is low, you’ll need an air compressor to inflate the tire.

Step-by-Step Guide to Checking Nitrogen Tire Pressure

Now that you have the tools ready, let’s proceed with the step-by-step process of checking nitrogen tire pressure:

1. Park your vehicle on a flat surface

Find a level and flat surface, such as a driveway or parking lot, to park your vehicle. This will ensure accurate pressure readings and prevent any accidents during the process.

2. Locate the tire valve stem

Identify the valve stem, which is a small rubber or metal tube sticking out from the wheel. It is usually capped to prevent dirt and debris from entering.

3. Remove the valve stem cap

Using your fingers or a valve stem cap removal tool, unscrew the valve stem cap and set it aside in a safe place. Be careful not to lose it, as it protects the valve stem from dirt and corrosion.

4. Check the current tire pressure

Attach the tire pressure gauge to the valve stem by firmly pressing it onto the valve. You may hear a hissing sound as air escapes but don’t worry, as this is normal. Wait for the gauge to display the current tire pressure.

Refer to your vehicle’s owner’s manual or the sticker located on the driver’s side door jamb to find the recommended tire pressure. Compare the reading on the gauge with the recommended pressure. If the reading is lower, you’ll need to inflate the tire. If it’s higher, you’ll need to release some air.

6. Inflate or deflate the tire if necessary

If the tire pressure is lower than the recommended pressure, use an air compressor to add more nitrogen to the tire. Attach the compressor to the valve stem and gradually add air while periodically checking the pressure with the gauge. If the tire pressure is higher than the recommended pressure, use a small tool like a valve stem core remover to release some air.

7. Recheck the tire pressure

After inflating or deflating the tire, reattach the tire pressure gauge to the valve stem to check the pressure again. Ensure that the reading matches the recommended pressure.

8. Repeat the process for all tires

Once you have checked and adjusted the pressure of one tire, repeat the same process for all the other tires on your vehicle. It is important to maintain consistent pressure in all tires for optimal performance.

Additional Tips for Maintaining Nitrogen Tire Pressure

Here are some additional tips to help you maintain the nitrogen tire pressure:

  • Regularly check the tire pressure: It is recommended to check your tire pressure at least once a month to ensure they are properly inflated. This will help prevent any potential issues and maintain optimal performance.
  • Check the pressure when the tires are cold: Tire pressure increases as the tires heat up during driving. To get accurate readings, always check the tire pressure when the tires are cold, preferably in the morning before driving.
  • Consider professional nitrogen tire filling: If you are not confident in checking and filling the nitrogen tire pressure yourself, consider visiting a professional tire service center that offers nitrogen tire filling. They have the expertise and equipment to ensure proper inflation.
  • Monitor tire tread depth: In addition to checking the tire pressure, regularly monitor the tread depth of your tires. Worn-out tires can affect handling and safety, so it’s important to replace them when necessary.
  • Replace damaged valve stem caps: If you notice any damage or cracks on the valve stem caps, replace them immediately. Damaged caps can allow dirt and moisture to enter the valve stem, leading to corrosion or leaks.
  • Consider a nitrogen tire inflation system: If you frequently deal with fluctuating tire pressure, investing in a nitrogen tire inflation system might be a good idea. These systems help maintain consistent tire pressure and reduce the need for frequent checks and adjustments.


Checking nitrogen tire pressure is an essential maintenance task that ensures your vehicle’s safety and performance. By following the step-by-step guide provided in this article, you can easily check and adjust the nitrogen tire pressure yourself. Remember to check your tire pressure regularly and maintain consistent pressure in all tires for optimal performance. Safe travels!
