This translates to more consistent tire pressure, helping to enhance the performance and lifespan of your tires.
Proper tire pressure is crucial for several reasons. It not only helps your tires last longer but also improves your vehicle’s handling and can even maximize your fuel economy. Under or over-inflated tires are more difficult to control and increase the risk of a tire blowout. By using nitrogen in your tires, you can set yourself up for tire success, particularly if you don’t have the time or expertise to regularly check your tire pressure.
But what about good ol’ air? There’s nothing wrong with using compressed air to fill your tires. In fact, it has been a trusted method for many drivers for years. Compressed air is readily available and often free. It’s convenient and cost-effective, making it the clear winner in terms of accessibility and cost.
While nitrogen offers advantages in maintaining tire pressure, it’s important to note that if you have nitrogen-filled tires and find yourself in a situation where nitrogen is unavailable, it is safe to top off your tires with compressed air. Mixing air and nitrogen won’t cause any harm to your tires, but it will dilute the purity of the nitrogen and reduce its effectiveness.
| Myth | Fact |
|---|---|
| Nitrogen does not leak from tires as quickly as compressed air, and therefore maintains proper tire pressure for a longer time. | Tires naturally lose small amounts of pressure over time, regardless of whether they are filled with compressed air or nitrogen. Major leaks occur due to valve or rubber punctures, and in these cases, oxygen and nitrogen escape at the same rate. |
| Nitrogen is not affected by temperature changes, and therefore maintains proper tire pressure regardless of climate. | While nitrogen-filled tires do maintain inflation pressure longer than compressed air-filled tires in fluctuating temperatures, under normal driving conditions, nitrogen does not completely eliminate temperature-related pressure changes. Proper tire maintenance is still necessary. |
| Using nitrogen in tires makes them “maintenance-free” so there is no need to regularly check tire pressures. | Tires filled with nitrogen still require regular pressure checks to identify slow leaks and should be visually inspected for other signs of tire trouble. |
| The lack of oxygen and moisture in a tire filled with nitrogen reduces the potential for chemical deterioration of the tire liner, and limits the possibility of rust and corrosion on the wheel. | Compressed air systems at most tire shops have moisture separators that limit water vapor in the air supply, protecting tires, wheels, and tools. The occurrence of tire and wheel damage caused by moisture is not widespread enough to justify special concern. |
In summary, whether you choose to fill your tires with nitrogen or compressed air, maintaining proper tire pressure is paramount. Properly inflated tires wear more evenly, provide better handling, improve fuel economy, and have a longer lifespan. Consult your vehicle’s recommended tire pressure and regularly check and maintain your tires for optimal performance and safety.
Nitrogen vs Regular Air: Debunking Myths
There are several myths surrounding the use of nitrogen in tires, but understanding the facts can help you make an informed decision. Let’s take a closer look at these misconceptions and separate fact from fiction.
Myth: Nitrogen does not leak from tires as quickly as compressed air, and therefore maintains proper tire pressure for a longer time.
Fact: Tires naturally lose small amounts of pressure over time whether they are filled with compressed air (oxygen) or nitrogen. If a tire has a major leak, air is likely escaping through the valve or punctures in the rubber, or from where the tire mounts to the wheel. In these cases, both oxygen and nitrogen escape at the same rate.
Myth: Nitrogen is not affected by temperature changes, and therefore maintains proper tire pressure regardless of climate.
Fact: Tires filled with nitrogen maintain inflation pressure longer than compressed air-filled tires in fluctuating temperatures. This is why nitrogen is used to fill airplane tires, as temperatures can change dramatically between takeoff and landing. Since nitrogen does not completely eliminate temperature-related pressure changes under normal driving conditions, it is of little benefit to vehicle owners who properly maintain their tires.
Myth: Using nitrogen in tires makes them “maintenance free” so there is no longer any need to check the tire pressures.
Fact: The opposite is true. Even tires filled with nitrogen still require regular pressure checks to identify slow leaks. It is also a good practice to visually inspect tires for cuts, tears, bulges and tread wear, or other signs of impending tire trouble.
Myth: The lack of oxygen and moisture in a tire filled with nitrogen reduces the potential for chemical deterioration of the tire liner, and limits the possibility of rust and corrosion on the wheel.
Fact: Compressed air systems at most tire shops have moisture separators that limit the amount of water vapor in the compressed air supply. Limiting water vapor protects the tires and wheels as well as a shop’s expensive air-powered tire mounting and installation tools. In relation to the number of vehicles on the road and the total number of tires sold annually, the occurrence of tire and wheel damage caused by moisture is not sufficiently widespread to justify any special concern.
Now that we have debunked these myths, it’s important to note that whether you choose to fill your tires with nitrogen or compressed air, the most crucial aspect of tire maintenance is maintaining proper tire pressure. Regular pressure checks and visual inspections are necessary to ensure your tires are in good shape and ready to take you on your next journey.
