Nitrogen in tires is becoming a popular replacement for standard air. Nitrogen is all around us. The aire we breathe is 78% nitrogen, 21% oxygen, and the rest is small amounts of other gasses. When it comes to tire inflation, nitrogen has many advantages over oxygen. With nitrogen tire inflation, improvements can be noted in a vehicle's handling, fuel efficiency and tire life through better tire pressure retention, improved fuel economy and cooler running tire temperatures.

Jay Leno on Nitrogen




If you are one of the 85% of Americans who don't regularly check tire pressure, you need nitrogen.
We take in nitrogen with every breath. Air is composed of:
  • 1% Water Vapor and Other Gases – Escapes up to 250 times faster than Nitrogen
  • 21% Oxygen – Escapes 3-4 times faster than Nitrogen
  • 78% Nitrogen – The largest molecule in
    air, dry, non-flammable.
Because of their large size, nitrogen molecules are the least permeable and stay in your tire longer. It's not about the nitrogen. It's about reducing oxygen, water vapor and other gases.By reducing the percentage of oxygen, water vapor and other gases in your tires from 22% to 7% or lower, your tires will maintain proper pressure longer than if you use “plain old air.” For example, with 95% nitrogen in your tires, they retain optimal pressure three to four times longer.

Proper tire pressure is a big deal. Maintain it with nitrogen, and you'll see these three primary benefits:
  • Increased Fuel Efficiency – Correct tire pressure keeps the manufacturer's recommended “contact patch” on the road. This lessens the rolling resistance and maximizes fuel efficiency.

  • Longer Tire Life – When it comes in contact with other materials, oxygen causes oxidation. Oxidation can make rubber brittle and cause it to lose tensile strength. In addition, at high temperatures and pressures, oxygen reacts and damages inner tire liners and belt packages; nitrogen does not.

  • Increased Safety – Under-inflated tires cause 90% of blowouts. Nitrogen provides more reliable pressure for reduced blowout potential.
Other benefits:
  • Improved TPMS Performance – If you have a new car, you likely are plagued by a flashing light telling you your tire pressure is low. For example, one woman's light was going off every four to five weeks. After inflating with nitrogen, her light didn't reappear for 53 weeks!

  • More Predictable Pressure Fluctuation – NASCAR teams use nitrogen so they can more accurately predict tire pressure fluctuation. Regular compressed air can fluctuate considerably when water vapor is present.

  • Longer Rim Life – Rim rust caused by condensation from water vapor and other gases can get caught in valves and create slow leaks in tires. Nitrogen is completely dry, so it eliminates the potential for condensation.
 

Why not eliminate all oxygen and water vapor?
What's right for me – 95% or 98%?

Numerous studies have proven that nitrogen in tires reduces the volume of gases that escape more quickly and cause damaging oxidation. However, research also has shown that nitrogen purity beyond a certain point does not provide additional benefits. In fact, with a nitrogen purity above 93.4%? in passenger tires, oxygen actually begins to migrate back into the tire. You can get all the benefits of nitrogen with a purity level between 93-98%.

  • Bridgestone/Firestone researchers say that 93-95% nitrogen is all you need.

  • According to Ford Motor Co., there is no difference between 96% and 99% nitrogen purity.
