Why Is Nitrogen Used in Tires?

The most common reason that people use nitrogen in their tires is because the gas will keep your tires inflated properly. The reason that this is the case is because nitrogen causes less wear and tear on the inside of the tire. As a result, you will notice that your car gets better gas mileage and that your tires last longer. This can be a very inexpensive way to ensure that your vehicle works much more efficiently for years to come.

Nitrogen allows for better gas mileage and longer lasting tires

Using nitrogen in your tires is an easy way to improve the lifespan of your tires, and drive more efficiently. When you’re traveling down the road, your tires are under a tremendous amount of pressure. That pressure can have some serious effects on rubber over time. Oxygen reacts chemically with rubber and causes oxidation, which slowly destroys a tire from the inside out. This can significantly reduce a tire’s lifespan.

Nitrogen has was shown to be less reactive with rubber than oxygen in laboratory tests. It also has a lower coefficient of expansion than oxygen, this means that as temperature changes, nitrogen will expand and contract at a much slower rate than air or oxygen; this reduces the stress on the sidewall and helps keep your tires running longer while maintaining their shape better.

Oxygen, which is what you’ll mostly find in your tires, causes tire pressure to fluctuate with temperature.

Oxygen, which is what you’ll mostly find in your tires, causes tire pressure to fluctuate with temperature. This is because oxygen molecules are much smaller than nitrogen molecules, and they’re therefore more likely to leak out of the tire. Nitrogen helps tires maintain a more consistent pressure.

Nitrogen causes less wear and tear on the inside of the tire

The first thing to know about nitrogen is that it’s good for your tires. It’s also good for your wallet, and the environment. Nitrogen prevents rubber from breaking down, which gives you longer-lasting tires and improves fuel efficiency (better air pressure = better gas mileage). Not only that, but by having less tire breakdown, you’ll save money on maintenance costs—no more buying new tires every other year!

Nitrogen also prevents rusting in the wheels. Rust can be extremely detrimental to your safety; if rust builds up enough in your wheel bearings or brake drums, it could cause them to crack and fail. Rust can also cause a vibration in your vehicle when it’s moving—this will wear out other parts of the car as well! Nitrogen helps prevent rust buildup by not letting moisture into those areas where water would normally collect with normal air-filled tires.

Nitrogen will help keep your tires inflated properly

Nitrogen molecules don’t expand as much when they’re heated, and they don’t contract as much when they’re cooled. Because of this, tires that have been filled with nitrogen will keep their pressure longer than tires that are filled with the air that’s outside. Here’s why that’s helpful:

  • Oxygen from air can leak out from the tire through the rubber. This means your tire is constantly losing pressure.
  • The constant loss of pressure can cause the tire to become flat and lose its shape. (This is called underinflation.) An underinflated tire could burst while you’re driving because it isn’t strong enough to hold all of its air anymore.
  • The change in shape may also cause your car to handle poorly on the road, which makes it more likely to get into an accident or a blowout—when a tire bursts while you’re driving.

nitrogen gives more stability to tires

When you fill your car tires with nitrogen, you’re doing more than just adding air to them. Nitrogen is a better choice than oxygen-based air because it’s less likely to fluctuate in temperature and pressure with changes in the surrounding environment. This means that tires filled with nitrogen are generally able to retain their proper pressure for longer periods of time compared to those filled only with oxygen-based air. This can help reduce wear on the tire and increase its lifespan.

Taking care of your tires is also important for fuel economy: if a tire is underinflated by just 5 pounds per square inch (psi), then driving one mile will require about the energy required to run about 1,000 light bulbs for one hour. That’s a lot of wasted energy! So not only does keeping your tires inflated help them last longer, but it also helps your car get better gas mileage, which can save you money at the pump. With both benefits in mind, using nitrogen over regular air becomes an even more appealing choice.
