In the car world, proper tire management is highly crucial for safety efficiency and performance. Traditionally tires are inflated with normal air, but for the past few years, nitrogen-filled tires have really become popular. But to what advantage? Are they really better? Let’s delve into the specifics of the benefits of nitrogen filled tires and separate facts from myths in this blog.
What Is Nitrogen-Filled Tire Inflation?
To understand the advantages, it’s essential to first explain what nitrogen-filled tires are. Like regular air, nitrogen is a gas used for tire inflation. However, nitrogen differs from the oxygen-rich air we commonly breathe. Nitrogen constitutes 78% of atmospheric air, while 21% is primarily oxygen.
USA Wheels and Tires provides expert insights into nitrogen-filled tires, emphasizing their benefits such as improved pressure retention, reduced moisture content, and enhanced tire longevity for superior performance.
For instance, in the example of tire inflation, its use is preferred for various purposes. It is dry and inert, which limits its interaction with the internal components in the tire or moisture if it contains any. This being the case, nitrogen becomes popular in commercial as well as racing vehicles.
Advantages of Nitrogen-Inflated Tires
Benefits of nitrogen inflation and their differences from air-filled tires can be listed as follows.
1. Better Pressure Retention of Tires
Nitrogen-filled tires are said to hold pressure better over time. Normal air is saturated with water vapor, which condenses in the tire and causes pressure fluctuations. Nitrogen, on the other hand, is a dry gas and doesn’t contribute to this problem.
The other benefit of nitrogen-tire inflation is that it leaks air through permeation less frequently. As a result, the pressure in your tires is topped off less often and, therefore, will change less over time. Safety, fuel efficiency, and the overall longevity of your tires also rely on proper tire pressure.
2. Extended Tire Life
With the proper tire pressure, tires are less likely to have uneven wear. Nitrogen-filled tires have an edge over others in this respect because of the fact that the pressure fluctuates less within nitrogen-filled tires. The tire, therefore, maintains better contact with the road and less heat is built up, resulting in less wear on the tire. Over time, it, therefore, increases the tire’s life span.
Nitrogen reduces the rate of wear, which, in turn, enables you to get more miles out of your tires, meaning fewer tires to replace, hence less money spent in the long run.
3. Improved Fuel Economy
Properly inflated tires help maximize fuel efficiency. When nitrogen is used, the tires hold their pressure longer, preventing underinflation, which can increase rolling resistance. With nitrogen-filled tires, vehicles experience less drag, hence better fuel economy.
While the difference in fuel savings may not be significant for daily commuters, the difference will build up with time, especially for users who drive extensively or manage fleets.
4. Increased Safety
Tires are more likely to have blowouts or sudden deflation, and these incidents are not only dangerous but also costly. Nitrogen-filled tires are less prone to rapid deflation than those filled with regular air. Because nitrogen is less sensitive to temperature variations and pressure changes, it helps maintain tire pressure regardless of the driving conditions. This leads to fewer underinflated tires, which are one of the most common causes of accidents.
Extreme driving or load conditions are furthered by nitrogen, which aids in the maintaining of tire pressure stability that, in turn, contributes to better safety while driving.
5. Less Corrosion and Oxidation
Since nitrogen is an inert gas, it doesn’t support the oxidation process that can occur when oxygen comes into contact with metal. This means that nitrogen-filled tires are less likely to experience internal corrosion of the rim or other tire components. Air, which contains moisture and oxygen, can cause rusting or damage to the rim and valve stem.
By reducing internal corrosion, nitrogen can help extend the life of your tires and wheels.
Myths About Nitrogen-Filled Tires
With any new technology or trend, myths are sure to spread. Let’s take a look at some common misconceptions about nitrogen-filled tires.
Myth 1: Nitrogen Is Only For High-Performance Vehicles
Nitrogen is typically used for high-performance vehicles, race cars, and those in business use. Its advantages benefit everyday consumer users. No matter if you operate a car, an SUV, or even a truck, nitrogen benefits are identical: improved holding of the tire pressure over time, longer tire longevity, and increased fuel consumption.
Myth 2: Filled Tires of Nitrogen Never Lose Pressure
While nitrogen-filled tires are better at maintaining pressure, they are not immune to losing air. All tires lose some pressure over time, whether filled with nitrogen or regular air. However, the rate of loss is slower with nitrogen, meaning you’ll have to top them off less frequently.
Myth 3: You Can’t Mix Nitrogen and Air in Tires
It is a myth that once you fill your tires with nitrogen, they should never be mixed with regular air. This is a misconception because it is possible to mix them in case you need to. Though the nitrogen concentration will go down when you add regular air, you will still enjoy many of the benefits. You will enjoy the benefits only if you maintain the recommended tire pressure.
Myth 4: Nitrogen Inflation Is Expensive and Inconvenient
Another myth is that nitrogen inflation is too expensive and not readily available. Although it is true that some service centers charge a small fee for nitrogen inflation, it is not prohibitively expensive. In many cases, it is offered as a complimentary service with tire purchase or as part of a routine maintenance package. Furthermore, nitrogen can often be found at gas stations or tire shops that offer the service.
Myth 5: Nitrogen Is the Only Way to Maintain Tire Pressure
Although nitrogen has some benefits, it’s not the only way to ensure proper tire pressure. As long as you regularly check your tire pressure, you can make regular air work for you and ensure they are always adequately inflated. The bottom line to proper tire life, safety, and fuel efficiency is to have a constant eye on the tire pressure.
How to Switch to Nitrogen-Filled Tires
If you’re convinced by the benefits and want to switch to nitrogen-filled tires, here’s a simple step-by-step process:
1. Visit a Service Center: Find a tire service provider that offers nitrogen inflation. Many tire shops and car dealerships now offer this service.
2. Replace or Refill Tires: If buying new tires, you can ask that they be filled with nitrogen. In case you have existing tires in your vehicle, the dealer can deflate the existing air in them and replace it with nitrogen.
3. Check Often: While the air in a nitrogen-filled tire lasts much longer than ordinary air, you still have to keep checking the tire pressure to maintain proper inflation.
Nitrogen-Filled Tires: Additional Advantages and Precautions
The Science Behind Nitrogen in Tires
To truly understand why nitrogen is better for your tires, it’s important to grasp the science behind it. Regular air, which is composed of about 78% nitrogen and 21% oxygen, also contains moisture. This moisture can lead to a number of problems in your tires over time. When the temperature changes, condensation of moisture inside the tire happens, which causes changes in pressure and increased stress to the rubber. Presence of oxygen in the air also affects oxidation of the internal materials within the tire, such as steel belts and valve stems. This weakens the tire and reduces its potential lifetime.
Nitrogen, however is dry and inert. Thus, it does not facilitate oxidation. Since nitrogen is less susceptible to temperature changes, it also keeps the pressure of the tire relatively stable. In this regard, filling your tires with nitrogen ensures you eliminate moisture buildup; thus, the life and performance of your tires are enhanced.
Nitrogen and Temperature Stability
The most important advantage of nitrogen-filled tires is that they are stable under extreme temperatures. The major reason for pressure loss in tires is temperature variation. For instance, when the temperature is low, the air inside the tire contracts, thus lowering the tire pressure. Conversely, in hot weather, the air inside the tire expands, causing overinflation.
Nitrogen, which is less sensitive to temperature changes, will assist in maintaining a more stable level of tire pressure both when very hot and when very cold. This is especially helpful for folks who live in regions of extreme temperature fluctuations or where the driver spends hours traversing different climates. Proper tire pressure is beneficial not only for safety but also in terms of performance and saving fuel.
Nitrogen for High-Performance Vehicles
Nitrogen inflation is widely used in commercial vehicles but more so in high-performance cars such as race cars and sports cars. Racing teams and professional drivers use it to make sure that their tires have the best performance during a race. Even a small variation in tire pressure can be a huge difference in how a vehicle handles, travels at speed, and safety of the vehicle during a race.
Nitrogen is very popular among vehicle enthusiasts and professionals because it can maintain uniform pressure under the most extreme operating conditions of driving. In most high-performance vehicles, tires need to be inflated to the extent that can help achieve the ideal handling and road grip; nitrogen-filled tires can enable this in various ways such as providing stability and reduction of potential tire-related problems.
The Environmental Impact of Nitrogen Inflation
There are environmental benefits to using nitrogen-filled tires. Tires that maintain the same pressure tend to consume less fuel, and the result of this is less emission. When the tire pressure is below the recommended, the vehicle has to work more to overcome the rolling resistance, which reduces the fuel efficiency but also increases carbon emissions.
With nitrogen-filled tires, improved fuel economy translates into lesser fuel consumption in the long run. It would therefore prove very helpful to a big fleet of commercial vehicles because fewer units are kept on road at any point of time. Savings from less consumption of fuel coupled with emissions decrease makes the process greener.
Do You Need to Change Over to Nitrogen Filled Tires?
Making the switch to nitrogen-filled tires is a personal choice depending on your driving habits, the climate you live in, and what your vehicle requires. Everyday drivers do not really need it, but certainly have several benefits in maintaining the tire, saving on fuel, and safety. It’s definitely worth considering for anyone who experiences extreme temperatures in their location or drives extensively every day.
For performance vehicle owners or those with commercial fleets, the advantages of nitrogen are more pronounced. The benefits of better pressure retention, improved handling, and reduced tire wear make nitrogen inflation a great option for high-performance and long-haul vehicles.
What to Expect When Switching to Nitrogen
Replacing to nitrogen-filled tires is pretty straightforward. If you’re having new tires installed, many tire shops will offer to inflate the tires with nitrogen. If you’re switching from air to nitrogen, the air has to be removed from your tires and then the tires have to be filled up with nitrogen. This is usually pretty quick and painless and most tire shops include it as part of their routine tire maintenance package.
The initial cost of nitrogen inflation will probably be slightly higher than in the case of regular air. Long-term savings due to an extended life for the tires, increased fuel efficiency, and lesser maintenance justify the expenditure. The advantages of using nitrogen become apparent with time if you care about vehicle safety and performance.
Conclusion
What are the advantages of nitrogen-filled tires? Simply, they have more benefits: better retention of tire pressure, longer life of a tire, safety, and the potential for fuel savings. Of course, not everybody needs to inflate their tires with nitrogen, but those who want to get their money’s worth out of their tire should consider this option, reducing the number of trips to the tire shop.
Understanding the facts surrounding nitrogen-filled tires and debunking the myths can help you make an informed decision. Whether you are in a performance vehicle, driving a family car, or running commercial fleets, nitrogen inflation can come with valuable advantages that may extend beyond just convenience.
