Why Nitrofill?

It’s not what nitrogen is that makes it such a beneficial inflation medium, but what it is not. Nitrogen is an “inert” gas, which basically means it is “nothing”…completely free of any properties. Essentially, it is the nothing that oxygen is combined with in our atmosphere so we humans can survive.

“Regular air,” the air that we breathe and compress to fill tires, is about 79.1% nitrogen and roughly 20% oxygen. While oxygen, again, is essential for us and almost every other living organism, it is detrimental to almost everything else, think “oxidation.” Oxidation, also known as rust and corrosion, is the absolute enemy of anything composed of rubber or steel. Without oxygen, it is impossible for oxidation to occur, i.e., no rim rust or corrosion, no TPMS sensor oxidization and no tire rot. Further, without the presence of oxygen, water or condensation cannot form in a tire, the “O” in H2O. Hence, no oxygen means no rust, no corrosion and no water or water related issues.

The greatest disadvantage of oxygen, however, is its molecular size. Air filled tires, as you probably know, lose pressure at the rate of at least one psi per month through normal “permeation.” Nitrogen filled tires, on the other hand, typically loses NO pressure over a one month period. This is because the size of a molecule of oxygen, which again comprises about 20% of regular air, is roughly ¼ of the size of a molecule of nitrogen. Under inflated tires run warmer, wear out faster and increase rolling resistance, which wastes energy, i.e. fuel…and nitrogen inflated tires stay properly inflated much longer.

A recent study indicates that oxygen free, or nitrogen inflated, tires can last up to 50% longer, provide up to 10% better fuel economy and fail much less frequently. Knowing these facts, no one can refute the value of keeping tires oxygen free.

Here's a summary of Nitrogen in Tires:

• Improves steering
• Improves handling
• Improves Braking
• Reduces chance of tire failure
• Dramatically slows pressure loss from permeation
• Improves fuel economy
• Reduces tire oxidation
• Eliminates interior wheel corrosion
• Reduces running temperatures
• Decreases false alarms and activation of Tire Pressure Monitoring System
