When it comes to vehicle safety, tire maintenance is crucial. One often overlooked aspect of tire maintenance is the type of gas used to inflate them. While oxygen is the most abundant gas in the air we breathe, it’s not the best choice for inflating tires. This is where nitrogen comes in – a colorless, odorless, and tasteless gas that makes up about 78% of the Earth’s atmosphere. In recent years, the use of nitrogen in tires has gained popularity, and for good reason.

The Importance of Proper Tire Inflation
Proper tire inflation is essential for ensuring the safety and performance of a vehicle. Underinflated tires can lead to reduced fuel efficiency, uneven tire wear, and increased risk of tire failure. On the other hand, overinflated tires can lead to reduced traction, increased stopping distance, and a higher risk of tire blowouts. With the importance of proper tire inflation in mind, it’s essential to understand why nitrogen is used in tires and how it compares to traditional compressed air.
A Brief Overview of Nitrogen in Tires
In this article, we’ll delve into the benefits of using nitrogen in tires, including its ability to maintain consistent tire pressure, reduce oxidation and corrosion, and improve fuel efficiency. We’ll also explore the differences between nitrogen and compressed air, and discuss the pros and cons of making the switch to nitrogen-filled tires. By the end of this article, you’ll have a better understanding of why nitrogen is used in tires and whether it’s the right choice for your vehicle.
Why Is Nitrogen Used In Tires?
Nitrogen has become a popular choice for inflating tires in recent years, and for good reason. While compressed air is still the most widely used gas for tire inflation, nitrogen offers several advantages that make it a preferred option for many vehicle owners. In this article, we’ll explore the reasons why nitrogen is used in tires and the benefits it provides.
The History of Nitrogen in Tires
The use of nitrogen in tires dates back to the 1960s, when it was first used in the aerospace industry. NASA used nitrogen to inflate the tires of spacecraft and aircraft because of its unique properties, which made it an ideal gas for high-performance applications. In the 1990s, the use of nitrogen in tires began to gain popularity in the automotive industry, particularly among racing teams and high-performance vehicle owners.
The Properties of Nitrogen
Nitrogen is a colorless, odorless, and tasteless gas that makes up approximately 78% of the Earth’s atmosphere. It has several properties that make it an ideal gas for tire inflation: (See Also: What Does 10 Ply Mean On Tires)
- Non-flammable: Nitrogen is a non-flammable gas, which reduces the risk of a tire explosion or fire in the event of a puncture or accident.
- Non-corrosive: Nitrogen does not react with the rubber compounds used in tires, which means it won’t cause corrosion or damage to the tire’s internal components.
- Moisture-free: Nitrogen is a dry gas, which means it doesn’t contain moisture that can seep into the tire and cause corrosion or damage.
- Consistent pressure: Nitrogen molecules are larger and heavier than oxygen molecules, which means they are less affected by temperature changes. This results in more consistent tire pressure.
Benefits of Nitrogen in Tires
The use of nitrogen in tires provides several benefits, including:
- Improved fuel efficiency: Properly inflated tires with nitrogen can improve fuel efficiency by up to 3%, which can lead to cost savings and reduced emissions.
- Increased tire life: Nitrogen helps to maintain consistent tire pressure, which can increase the life of the tire by up to 20%.
- Enhanced safety: Nitrogen-filled tires are less prone to overheating and blowouts, which can reduce the risk of accidents.
- Reduced maintenance: Nitrogen-filled tires require less frequent pressure checks and adjustments, which can reduce maintenance costs and downtime.
How Nitrogen Affects Tire Pressure
Tire pressure is affected by several factors, including temperature, humidity, and the type of gas used for inflation. Nitrogen is less affected by temperature changes than compressed air, which means it provides more consistent tire pressure:
| Temperature (°F) | Compressed Air Pressure (PSI) | Nitrogen Pressure (PSI) |
|---|---|---|
| 32 | 35 | 35 |
| 70 | 37 | 36 |
| 100 | 40 | 37 |
As the table shows, compressed air pressure increases more significantly with temperature changes than nitrogen pressure. This means that nitrogen-filled tires are less prone to over-inflation or under-inflation, which can lead to reduced tire life and decreased fuel efficiency.
Myths About Nitrogen in Tires
There are several myths and misconceptions about the use of nitrogen in tires, including:
- Nitrogen is only for high-performance vehicles: While nitrogen was initially used in high-performance applications, its benefits apply to all types of vehicles.
- Nitrogen is too expensive: While the initial cost of nitrogen may be higher than compressed air, the long-term benefits and cost savings make it a worthwhile investment.
- Nitrogen is difficult to find: Nitrogen is widely available at most tire shops and service centers, and many dealerships and manufacturers offer nitrogen filling as an option.
Conclusion
In conclusion, the use of nitrogen in tires provides several benefits, including improved fuel efficiency, increased tire life, enhanced safety, and reduced maintenance. While there may be some initial costs associated with switching to nitrogen, the long-term benefits make it a worthwhile investment for many vehicle owners. By understanding the properties and benefits of nitrogen, vehicle owners can make an informed decision about whether to switch to nitrogen-filled tires.

Frequently Asked Questions: Why Is Nitrogen Used In Tires
What are the benefits of using nitrogen in tires?
Nitrogen is used in tires because it provides several benefits, including improved tire pressure retention, reduced moisture content, and slower oxidation of the tire’s rubber compounds. This results in better fuel efficiency, longer tire life, and increased safety on the road.
Is nitrogen better than compressed air for tires?
Yes, nitrogen is considered better than compressed air for tires because it is a dry, inert gas that doesn’t contain moisture or oxygen. Compressed air, on the other hand, can contain up to 20% oxygen and 5% moisture, which can cause tire degradation and pressure loss over time.
Do I need to check my tire pressure more often if I use nitrogen?
No, you don’t 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 maintain consistent tire pressure over time, reducing the need for frequent checks. (See Also: What Size Rims For 18 Inch Tires)
Can I mix nitrogen with compressed air in my tires?
No, it’s not recommended to mix nitrogen with compressed air in your tires. Doing so can negate the benefits of using nitrogen and may even cause damage to your tires or tire pressure monitoring system (TPMS). It’s best to use pure nitrogen or compressed air, but not a mixture of both.
Is nitrogen more expensive than compressed air for tires?
The cost of nitrogen for tires can vary depending on the location and service provider. However, in general, nitrogen is slightly more expensive than compressed air. However, the benefits of using nitrogen, including improved fuel efficiency and longer tire life, can outweigh the additional cost over time.
