Why Nitrogen Inflation? Does it really work?
Nitrogen is a larger molecule than oxygen (by approx. 6 times). As a result Nitrogen migrates out of tires at a significantly SLOWER rate than compressed air. — NHTSA (National Highway Traffic Safety Administration)
Maintaining proper tire pressure SAVES GAS by reducing rolling resistance. Saving gas is good for our economy and environment. AAA tells us that 1 out of every 3 cars on the road has at least 1 tire significantly under inflated (that is down 8+ lbs and driving towards you). Tests have shown that few people can detect under inflation of up to 9 lbs by looking at a tire.
Proper inflation SAVE LIVES — under inflated tires are a leading cause of blowouts. 414 deaths and 23,464 injuries each year, on average, are due to blowout related crashes. — NHTSA
Properly inflated tires EXTEND TIRE LIFE — the tread contact patch meets the road as designed, reducing uneven wear and saving sidewalls.
Nitrogen inflated tires are LESS AFFECTED by heat and cold than tires filled with compressed air. Managing tire temperatures is one reason NASCAR® inflates tires with Nitrogen. For our safety the FAA mandates that airliner tires be inflated with Nitrogen.
What is Oxidation? Why does it matter?
Oxidation is the chemical process by which oxygen breaks down much of the world around us. It works inside tires that can look perfectly serviceable on the outside. Oxidation destruction is one reason DOT requires a build date stamp on tires. Oxidation causes potato chips to go stale once the bag is opened (to extend shelf life nitrogen is blown into the bags just before sealing). It is also why rubber bands are no longer elastic in a short time. Research has shown that even a small amount of oxygen eats tires from the inside. Add road and summer heat to the oxygen and water vapor in compressed air and the destruction of inner liners and steel belts is speeded up. Oxidation also corrodes aluminum rims and valve stems. Studies have shown that tires filled with at least 95% dry Nitrogen slow this deadly oxidation.
