When it comes to vehicle maintenance, one of the most crucial aspects is ensuring the proper inflation of tires. While many people may be familiar with the concept of filling tires with air, a growing trend has emerged in recent years: filling tires with nitrogen. But why are tires filled with nitrogen, and what are the benefits of doing so?

Overview
The use of nitrogen in tires has become increasingly popular, particularly among high-performance and commercial vehicles. However, it’s not just limited to these types of vehicles – many everyday drivers are also making the switch to nitrogen-filled tires. But what makes nitrogen so special, and why is it preferred over traditional compressed air?
A Brief History of Nitrogen in Tires
The concept of using nitrogen in tires dates back to the 1970s, when it was first used in aircraft and racing tires. The idea was to reduce the risk of tire failure due to moisture and oxygen, which can cause corrosion and degradation of the tire’s internal components. Since then, the use of nitrogen has expanded to other industries, including commercial and passenger vehicles.
In this article, we’ll delve into the reasons why tires are filled with nitrogen, exploring the benefits and advantages of this practice. From improved safety and performance to increased fuel efficiency and reduced maintenance costs, we’ll examine the various reasons why nitrogen has become the go-to choice for many vehicle owners.
Why Are Tires Filled With Nitrogen?
Tires are an essential component of a vehicle, and their proper maintenance is crucial for ensuring safety on the road. One aspect of tire maintenance that often raises questions is the use of nitrogen to fill tires instead of compressed air. In this article, we will delve into the reasons why tires are filled with nitrogen and explore the benefits of doing so.
The History of Nitrogen in Tires
The use of nitrogen in tires dates back to the 1970s, when it was first introduced in the aircraft industry. The primary reason for using nitrogen was to reduce the risk of tire explosions caused by oxygen combustion. The success of nitrogen-filled tires in the aviation industry led to its adoption in other fields, including the automotive industry. (See Also: When To Put Chains On Tires)
What is Nitrogen?
Nitrogen is a colorless, odorless, and tasteless gas that makes up approximately 78% of the Earth’s atmosphere. It is a non-reactive gas, meaning it does not react with other elements to form compounds. This property makes nitrogen an ideal gas for filling tires.
Benefits of Nitrogen-Filled Tires
There are several benefits to filling tires with nitrogen instead of compressed air:
- Improved Tire Pressure Retention: Nitrogen molecules are larger than oxygen molecules, which means they escape from the tire more slowly. This results in better tire pressure retention, reducing the need for frequent tire pressure checks.
- Reduced Tire Oxidation: Oxygen can react with the rubber compounds in tires, causing them to degrade over time. Nitrogen, being a non-reactive gas, reduces the risk of tire oxidation, leading to longer tire life.
- Increased Fuel Efficiency: Properly inflated tires can improve fuel efficiency by up to 3%. Nitrogen-filled tires maintain their pressure better, resulting in improved fuel efficiency.
- Enhanced Safety: Underinflated tires can lead to tire blowouts, which can be catastrophic. Nitrogen-filled tires are less likely to experience blowouts due to their improved pressure retention.
- Reduced Moisture Content: Compressed air can contain up to 20% moisture, which can lead to corrosion of the tire’s rim and wheel components. Nitrogen, on the other hand, has a much lower moisture content, reducing the risk of corrosion.
- Improved Handling and Performance: Nitrogen-filled tires can improve a vehicle’s handling and performance due to their ability to maintain consistent pressure.
How Nitrogen-Filled Tires Compare to Air-Filled Tires
To better understand the benefits of nitrogen-filled tires, let’s compare them to air-filled tires:
| Characteristic | Air-Filled Tires | Nitrogen-Filled Tires |
|---|---|---|
| Tire Pressure Retention | Poor | Excellent |
| Tire Oxidation | High Risk | Low Risk |
| Fuel Efficiency | Average | Improved |
| Safety | Higher Risk of Blowouts | Lower Risk of Blowouts |
| Moisture Content | Up to 20% | Less than 1% |
| Handling and Performance | Average | Improved |
Challenges and Limitations of Nitrogen-Filled Tires
While nitrogen-filled tires offer several benefits, there are some challenges and limitations to consider:
- Availability: Nitrogen filling stations may not be as common as compressed air stations, making it more difficult to find a location to fill up.
- Cost: Nitrogen is more expensive than compressed air, which can be a deterrent for some vehicle owners.
- Equipment Requirements: Filling tires with nitrogen requires specialized equipment, which can be a significant investment for tire shops and service stations.
- Conversion Process: Converting from air-filled to nitrogen-filled tires requires a thorough cleaning and drying process to remove any moisture and contaminants.
Conclusion
In conclusion, filling tires with nitrogen offers several benefits over compressed air, including improved tire pressure retention, reduced tire oxidation, increased fuel efficiency, enhanced safety, reduced moisture content, and improved handling and performance. While there are some challenges and limitations to consider, the benefits of nitrogen-filled tires make them a worthwhile investment for vehicle owners who prioritize safety and performance.

Frequently Asked Questions: Why Are Tires Filled With Nitrogen
What are the benefits of filling tires with nitrogen?
Filling tires with nitrogen provides several benefits, including improved tire pressure retention, reduced tire temperature, and increased fuel efficiency. Nitrogen molecules are larger and more stable than oxygen molecules, which means they escape from the tire more slowly, resulting in more consistent tire pressure. This can lead to better fuel economy, improved handling, and increased tire lifespan.
Is nitrogen better than compressed air for tires?
Yes, nitrogen is generally considered better than compressed air for tires. Compressed air contains a high percentage of oxygen, which can cause tires to oxidize and degrade over time. Nitrogen, on the other hand, is an inert gas that does not react with the tire’s rubber compounds, reducing the risk of oxidation and damage. Additionally, nitrogen is less prone to moisture absorption, which can lead to tire corrosion.
Do I need to check my tire pressure more often if I use nitrogen?
No, you do not need to check your tire pressure more often if you use nitrogen. In fact, one of the benefits of using nitrogen is that it helps to maintain consistent tire pressure over time. However, it’s still important to regularly check your tire pressure to ensure it’s at the recommended level, as specified in your vehicle’s owner’s manual. (See Also: Can You Balance Tires Yourself)
Can I fill my tires with nitrogen myself, or do I need to go to a professional?
You can fill your tires with nitrogen yourself, but it’s recommended to have it done by a professional. Many tire shops and service centers offer nitrogen filling services, and they will have the necessary equipment and expertise to do the job correctly. If you do decide to fill your tires with nitrogen yourself, make sure to use a high-quality nitrogen source and follow proper safety procedures.
Is nitrogen filling more expensive than compressed air?
The cost of nitrogen filling can vary depending on the location and service provider. In some cases, nitrogen filling may be slightly more expensive than compressed air, but the benefits it provides can make it a worthwhile investment. Additionally, many tire shops and service centers offer nitrogen filling as a standard service, so it may not be an additional cost. It’s always a good idea to check with your local service provider for pricing and availability.
