Nitrogen

The Benefits:

As fuel costs keep going up, regulations to protect the environment are tightening down. When you use "plain old air" in your tires, you're caught in the middle. Fortunately, there's an answer: nitrogen.

NASA, the U.S. military, Boeing, Indy and NASCAR race teams all use nitrogen in their tires, and for good reason. Nitrogen provides more consistent tire pressure for better handling, enhanced saftey and longer tire life. You might not be driving the Space shuttle or a racecar at 200 mph, but you deserve the same benefits.

Using nitrogen in you tires pays for itself in no time when you factor in better fuel economy and fewer tire purchases. Plus, it's better for the environment, so you'll not only be doing yourself a financial favor, you'll be helping make the world a better place.

The FACTS:

Nitrogen is an inert, dry, non-flammable gas that's all around us. The air we breathe is 78 percent nitrogen, 21 percent oxygen and small amounts of other gasses.

Better Pressure Retention
Because of its larger molecular size, nitrogen migrates through a tire three to four times slower than oxygen. A tire filled with "plain old air" will lose 1.5 PSI in less than a month; with nitrogen, it could take three months or longer.

Improved Handling
Proper tire inflation ensures the recommended "contact patch" of your tire is on the road.

Higher Fuel Economy
Proper tire pressure lessens rolling resistance and maximizes fuel efficiency.

Enhanced Safety and Reliability
Under-inflated tires cause 90 percent of blowouts. Nitrogen provides more reliable pressure for reduced blowout potential.

Longer Tire Life
Under-inflated tires wear quickly on the shoulders, and over-inflated tires wear in the center. In addition, removing oxygen eliminates oxidation and condensation that can damage inner liners, steel belts and rims.

Better For The Environment
Anything that improves fuel efficiency and reduces toxic emmissions is good for the environment, and nitrogen in your tires can help.
