Nitrogen Tyre Inflation vs Regular Air Inflation

09 13,2023

Nitrogen tyre inflation is a relatively new technology that has been gaining popularity in recent years. It is often touted as a way to improve fuel economy, extend tyre life, and enhance handling. But is nitrogen tyre inflation really worth the cost?

What is nitrogen tyre inflation?

Nitrogen tyre inflation is simply the process of filling your tyres with nitrogen gas instead of compressed air. Nitrogen is a non-reactive gas that makes up about 78% of the Earth's atmosphere. It is also the main component of dry air, which is used to inflate tyres.

Why use nitrogen in tyres?

There are several reasons why people choose to inflate their tyres with nitrogen. Some of the potential benefits include:

Slower pressure loss:

Nitrogen molecules are larger than oxygen molecules, so they are less likely to permeate the tyre walls and escape. This can help to maintain proper tyre pressure for longer periods of time.

Reduced oxidation:

Nitrogen is an inert gas, so it does not react with the metal components of your wheels. This can help to prevent rust and corrosion.

Improved fuel economy:

Some studies have shown that nitrogen tyre inflation can improve fuel economy by up to 1%.

Extended tyre life:

By maintaining proper tyre pressure, nitrogen tyre inflation can help to extend the life of your tyres.

Increased safety:

Properly inflated tyres can improve handling and braking performance, which can help to keep you safe on the road.

Nitrogen tyre inflation disadvantages

Despite the potential benefits, there are also some drawbacks to nitrogen tyre inflation. Some of the disadvantages include:

  • Cost: Nitrogen tyre inflation is typically more expensive than traditional compressed air inflation.
  • Availability: Not all tire shops offer nitrogen tyre inflation.
  • Maintenance: Nitrogen-filled tyres still need to be checked for pressure regularly.

Is nitrogen tyre inflation right for you?

Whether or not nitrogen tyre inflation is right for you depends on your individual needs and driving habits. If you are a frequent traveler or if you drive in extreme weather conditions, then nitrogen tyre inflation may be a good option for you. However, if you are on a tight budget or if you do not drive very often, then you may not see the benefits of nitrogen tyre inflation.

Additional considerations

  • The quality of the nitrogen used: Not all nitrogen is created equal. Some tire shops may use lower-quality nitrogen that does not offer the same benefits as higher-quality nitrogen.
  • The type of tyres: Nitrogen tyre inflation may not be as beneficial for some types of tyres, such as high-performance tyres.


Nitrogen tyre inflation is a relatively new technology that has the potential to offer several benefits, such as slower pressure loss, reduced oxidation, improved fuel economy, extended tyre life, and increased safety. However, it is also more expensive than traditional compressed air inflation and not as widely available. Ultimately, the decision of whether or not to use nitrogen tyre inflation is a personal one.
