Nitrogen Filled Tires
Nitrogen vs. Air Filled Tires ? Truth or Hype
What is Nitrogen you ask? Nitrogen is a DRY light gas that doesn't burn. In fact, the air we breathe is made up of 78% nitrogen. This molecule is a much safer alternative for your tires. You might not know that most commercial vehicles, military aircraft, Formula 1, NASCAR, and Indy cars use it as well.
Alright, we all know the importance of maintaining the right tire pressure. It is in fact the single best thing you can do for your tires. It's so important that even the National Highway Traffic Safety Administration (NHTSA) now requires all manufacturers to install Tire Pressure Monitoring System(s) (TPMS) in all light vehicles. This alerts drivers when a tire becomes under-inflated and in some cases, over inflation.
Here is a bullet point of the benefits:
Because nitrogen is non-flammable and doesn't support combustion, it reduces the risk of excessive heat build-up in your tires. Fact, nitrogen inflated tires run consistently 20% cooler than air filled.
It's obvious that properly filled tires improve gas mileage. Combine that with the fact that nitrogen inflated tires run cooler, now you get and EPA improvement of two to three miles per gallon (4% on average). At 4% increased EPA, a vehicle with an average EPA of 20 mpg would save approximately 2.5 gallons per week. Based on 40 miles per day @ 3.89 per gallon = a savings of over $500 per year!
Alright, let's break this down. Compressed air is about 21% oxygen. The reason why oxygen eats up tires is because it reacts chemically with rubber as it passes through it, causing the rubber to lose its elasticity and strength. Picture an old rubber band. You know how they get all brittle? Similarly, oxygen consumes the tire liner and ravages the insulating rubber as it permeates through the entire casing. This damage is increased by the pressure difference between the tire and the atmosphere.
Compressed air also contains moisture. Moisture corrodes. Therefore decreasing tire and wheel life. Water vapor and oxygen destroy tiers by forming rust in steel body plies, valve stems, and wheels. Oxygen and moisture also create aluminum hydroxide, which corrodes aluminum wheels and rims. The result is premature again, such as tread separation, cracking and blowout.
The second most expensive operating expense after fuels is tire repairs OR replacement. Inflating your tires with nitrogen can give you up to 25% more mileage. Not to mention the peace of mind that your family is riding on safe, cool, nitrogen filled tires.
AAA (American Automobile Association)
Under inflated tires can cut fuel economy by as much as 2% per pound of pressure below the recommended level. Therefore a tire that is just five pounds below its setting will consume 10% more fuel. Additionally, tires with low air pressure are more sluggish in their response to steering input...compromising your vehicle's handling.

Here is a bullet point of the benefits:- Nitrogen maintains pressure better than conventional air
- Nitrogen keeps tires 20% cooler
- Nitrogen-filled tires use less fuel
- Nitrogen prolongs the life of your tires
- Tests show that nitrogen reduces tire failure by as much as 80%
- Nitrogen improves handling and performance
