Nitrogen Filled Tires?

Why Should I fill My Tires With Nitrogen?

How Nitrogen in Car Tires Works...

Nitrogen (N2) is AIR, more specifically, AIR is between 79% and 80% Nitrogen and is what we all breathe everyday. The remaining components in our breathable air is combined mostly of oxygen and CO2. Nitrogen is colorless, tasteless and (obviously) non toxic.
Carbon dioxide is a greenhouse gas which makes up about 0.038% of the Earth's atmosphere. CO2 has been, and continuse to be created (abundantly so) by the burning of fossil fuels. Combined with its long residence time in the atmosphere, this has made carbon dioxide the leading cause of man-made global warming.
As a nitrogen molecule is about 3% larger than an oxygen molecule, it does not escape through the tire wall as easily as oxygen can and therefore leaks at a much slower rate than oxygen. A car tire filled with Nitrogen is estimated to maintain the same pressure approximately three to four times longer than oxygen-filled tires. Proper inflation provides better fuel economy, tire specific handling properties, increased tire life and increased safety for your family. All of this being based on the tires maintaining the proper air pressure over a more consistent period of time.

Nitrogen (NO2) is a Dry, Inert Gas...

An Oxygen filled tire provides unwanted oxidation which serves to breakdown the rubber in tires, and corrodes (steel) wheels. Nitrogen is a harmless gas which does not react negatively with rubber tires and steel wheels, nitrogen filled tires reduces tire heat, therefore decreasing rolling resistance and or friction, and increasing fuel economy.

Nitrogen is a Non-Flammable Gas...
A large number of mass transportation companies around the world fill truck tires with Nitrogen for added safety. Should a vehicle catch fire, ruptured oxygen filled tires fuel the fire. N2 filled tires do not add fuel to the fire should they leak or rupture.

Key Advantages of Nitrogen Filled Tires

  • Increased Mpg / Fuel Savings!
  • Increased Safety
  • Longer Tire Life
  • Increased Tread Life
  • Tire Maintain Handling Characteristics
  • Decreased Wheel Corrosion (inside)
  • Maintains Proper Inflation 3 to 4 Times Longer!

Nitrogen Filled Tires may NOT be for Everyone

  1. Nitrogen is more efficient in tires that experience wide temperature extremes such as freight trucks and Indy Cars

  2. Using nitrogen gas does appear to reduce the aging of tires, seemingly most pronounced for peel strength (the force required to separate the belts in the radial tires tested).(study)

  3. Does using nitrogen vs air in car tires make any difference?   As consumers, it is doubtful that at $6.00 (or more) per tire when just periodic checking of pressure is sufficient, that any money would ever be saved. Should we happen to have two quarters available when we think about it to check and fill our tires, our tires would likely stay at a more constant pressure. This whole controversy merely serves to show how organizations can and will, exploit a partial truth and through a little marketing can produce a new perceived need (and expense)for the consumer.
