Is nitrogen bigger than oxygen?
An atom of nitrogen is a tiny bit bigger than an atom of oxygen, and therefore less able to permeate rubber and escape from a tire.</p> <p>The math is complicated, but the deal is that air escapes from a tire 1.6 times faster than nitrogen. Keep in mind, however, that even if you have nitrogen inside your tires, ...
Why is nitrogen important for tires?
Because nitrogen has a larger molecule size than oxygen, it is less permeable, meaning that it leaks through your tires much more slowly than oxygen does. This allows the pressure in your tires to remain stable over an extended period of time—which is very helpful if you’re one of the estimated 85% of people throughout the United States who doesn’t check your tire pressure regularly! In addition, nitrogen has the added benefit of helping your tires maintain a constant pressure even in hotter weather. Of course, the climate of the San Diego area is relatively mild year-round, but nitrogen’s added benefits are still likely to be noticeable during the region’s summer months.
Why fill tires with nitrogen?
Heat is the enemy of your car tires, as hot tires can suffer from excessive sidewall flexing, meaning that the side of the tire bends and stretches, weakening the rubber. Sidewall flexing wears tires out quickly and puts your vehicle at risk for serious issues like blowouts. However, filling your tires with nitrogen instead of compressed air helps ensure that your tires remain as cool as possible. When you fill your tires with normal compressed air, the air’s natural humidity can be problematic for the safety of your vehicle: water vapor absorbs and holds heat, making your tires run hotter as you drive. However, filling your tires with pure nitrogen reduces the risk of these issues, as this gas will not contribute to fluctuations in pressure. In addition, nitrogen itself does not heat up as quickly as compressed air does, allowing you to further reduce the risk of blowouts and other tire issues.
Why do tires wear out?
Tire wear is caused by the oxidation of the rubber, as oxygen attacks and breaks down the bonds in this material over time. Nitrogen, however, is an inert gas, meaning that it does not react to many other substances and can be used to avoid chemical reactions like oxidation. Normal compressed air consists of 79.1% nitrogen, but using regular air means that your tires will also be filled with oxygen, which contributes to oxidation in your tires.
How We Tested Air Loss
Consumer Reports conducted a 12-month study at our Auto Test Center using 31 tire models of all-season tires. The tires and wheels were purchased new, and they were used for our 16,000-mile treadwear test.
What NHTSA Found
The NHTSA study also found that regular air escapes tires at a higher rate than pure nitrogen does.
Temperature changes and tire pressure
Tire pressure in your vehicle changes according to the ambient temperature. This happens because the gas inside the tires will expand when the temperature rises and contracts when the temperature is cold.
Tire pressure in nitrogen-filled tires
Like regular air, nitrogen too will compress and expand when the temperature changes. But the time taken for the pressure to change in nitrogen-filled tires is usually longer than in compressed air-filled tires. Airplane tires use nitrogen because temperatures can change drastically during take-off and landing.
What are the pros and cons of using nitrogen in tires?
Nitrogen is more stable: As we mentioned above, nitrogen tires can withstand heat longer, and the pressure bleed will be slower when compared to compressed air.
Can I fill regular air in a tire filled with nitrogen?
