What Kind of Air Goes in Tires?
When it comes to maintaining your vehicle’s tires, one of the most important aspects is ensuring they are properly inflated. But have you ever stopped to think about what kind of air goes into your tires? Is it just regular air, or is there something special about the air that goes into tires? In this article, we’ll explore the different types of air that can be used in tires, the benefits and drawbacks of each, and what you need to know to keep your tires running smoothly.
Nitrogen vs. Compressed Air
The two most common types of air used in tires are nitrogen and compressed air. While both can be used, they have some key differences that are important to understand.
Nitrogen
Nitrogen is a colorless, odorless, and tasteless gas that makes up about 78% of the Earth’s atmosphere. It’s a popular choice for tire inflation because it has several benefits:
- Less moisture: Nitrogen contains very little moisture, which means it won’t contribute to the corrosion of metal components inside the tire or wheel.
- More consistent pressure: Nitrogen molecules are larger than oxygen molecules, which means they are less affected by temperature changes. This results in more consistent tire pressure, even in extreme temperatures.
- Slower leakage: Nitrogen molecules are larger than oxygen molecules, which makes them less likely to seep out of the tire over time.
- Improved fuel efficiency: Properly inflated tires with nitrogen can improve fuel efficiency due to reduced rolling resistance.
However, nitrogen also has some drawbacks:
- Higher cost: Nitrogen is more expensive than compressed air, especially for large quantities.
- Less availability: Nitrogen may not be as widely available as compressed air, especially in rural areas.
Compressed Air
Compressed air, on the other hand, is a mixture of gases that includes oxygen, nitrogen, and other gases. It’s the most commonly used type of air for tire inflation and has its own set of benefits and drawbacks: (See Also: Where To Buy Trailer Tires)
- Widely available: Compressed air is widely available at most gas stations and service centers.
- Less expensive: Compressed air is generally less expensive than nitrogen.
However, compressed air also has some drawbacks:
- More moisture: Compressed air can contain high levels of moisture, which can contribute to corrosion inside the tire or wheel.
- More temperature sensitivity: Compressed air is more affected by temperature changes, which can result in inconsistent tire pressure.
- Faster leakage: Compressed air molecules are smaller than nitrogen molecules, which means they can seep out of the tire more quickly.
Oxygen-Free Air
Oxygen-free air is a type of air that has had the oxygen removed, leaving behind mostly nitrogen and other inert gases. This type of air is often used in high-performance tires or in applications where the risk of oxidation is high.
The benefits of oxygen-free air include:
- Reduced oxidation: Oxygen-free air reduces the risk of oxidation, which can cause tire degradation and failure.
- Improved tire life: Oxygen-free air can help extend the life of high-performance tires.
However, oxygen-free air also has some drawbacks:
- Higher cost: Oxygen-free air is more expensive than compressed air or nitrogen.
- Less availability: Oxygen-free air may not be as widely available as compressed air or nitrogen.
Helium and Other Gases
While nitrogen, compressed air, and oxygen-free air are the most common types of air used in tires, there are other gases that can be used in specific applications.
Helium, for example, is sometimes used in tires for high-speed applications, such as racing or high-performance driving. Helium is lighter than air, which can improve tire performance and reduce rolling resistance. However, helium is also more expensive than other types of air and can be difficult to find.
Other gases, such as argon and neon, are sometimes used in specialized applications, such as in the aerospace industry or in high-pressure tires. However, these gases are typically not used in standard vehicle tires. (See Also: What Size Tires Does My Car Have)
What Kind of Air Should You Use?
So, what kind of air should you use in your tires? The answer depends on several factors, including:
- Tire type: If you have high-performance tires, oxygen-free air or nitrogen may be a good choice. For standard tires, compressed air is usually sufficient.
- Driving conditions: If you drive in extreme temperatures or carry heavy loads, nitrogen or oxygen-free air may be a good choice.
- Availability: If nitrogen or oxygen-free air is not readily available in your area, compressed air may be the best option.
- Cost: If budget is a concern, compressed air may be the most cost-effective option.
Ultimately, the type of air you choose will depend on your specific needs and circumstances. It’s always a good idea to consult with a tire professional or the manufacturer’s recommendations to determine the best type of air for your tires.
Conclusion
In conclusion, the type of air that goes into your tires is an important consideration for maintaining proper tire pressure and extending the life of your tires. While compressed air is the most widely available and cost-effective option, nitrogen and oxygen-free air may be better choices for certain applications. By understanding the benefits and drawbacks of each type of air, you can make an informed decision about what kind of air to use in your tires.
Remember, proper tire inflation is critical for safety, fuel efficiency, and tire longevity. Regardless of the type of air you choose, make sure to check your tire pressure regularly and maintain the recommended pressure for your vehicle.
Recap
In this article, we discussed the different types of air that can be used in tires, including:
- Nitrogen: A popular choice for tire inflation due to its low moisture content, consistent pressure, and slow leakage rate.
- Compressed air: The most widely available and cost-effective option, but may contain high levels of moisture and be more sensitive to temperature changes.
- Oxygen-free air: A type of air that has had the oxygen removed, often used in high-performance tires or applications where oxidation is a concern.
- Helium and other gases: Used in specialized applications, such as high-speed racing or aerospace industries.

Frequently Asked Questions: What Kind of Air Goes in Tires
What is the recommended air pressure for my tires?
The recommended air pressure for your tires can be found in your vehicle’s owner’s manual or on the tire information placard, usually located on the driver’s side doorjamb or inside the fuel filler door. It’s important to follow the recommended pressure, as underinflated tires can lead to reduced fuel efficiency, uneven tire wear, and increased risk of a blowout.

Can I use compressed air from a gas station to fill my tires?
While it’s technically possible to use compressed air from a gas station to fill your tires, it’s not recommended. Gas station air compressors can introduce moisture and contaminants into your tires, which can cause corrosion and damage to the tire’s inner lining. It’s best to use a clean, dry air source, such as a home air compressor or a tire shop’s air supply.
What’s the difference between nitrogen and compressed air for tires?
Nitrogen is a popular alternative to compressed air for tire inflation because it’s a dry, inert gas that won’t react with the tire’s rubber compounds or introduce moisture. This can help to maintain tire pressure longer and reduce the risk of corrosion. However, the benefits of nitrogen are most significant for high-performance or racing tires, and may not be noticeable for everyday driving.
Can I use oxygen to fill my tires?
No, it’s not recommended to use oxygen to fill your tires. Oxygen can react with the tire’s rubber compounds and cause them to deteriorate more quickly, leading to reduced tire life and increased risk of a blowout. Additionally, oxygen can ignite more easily than air, which can increase the risk of a fire in the event of a tire failure.
How often should I check my tire pressure?
It’s a good idea to check your tire pressure at least once a month, as well as before long trips or when carrying heavy loads. You should also check your tire pressure when the temperature changes significantly, as this can affect the pressure reading. Regular tire pressure checks can help to ensure your safety on the road and maintain optimal fuel efficiency.
