For more than a century, drivers have filled their tires with plain old air - 78% percent nitrogen, 21% percent oxygen, water vapor, and a trace amounts of other gases. But is air really the best option for keeping your tires in the best possible shape? Surprisingly, the answer is no. The best alternative to plain old air is to go 100% nitrogen.
As an inert gas, nitrogen puts nothing into your tires other than pressure. On the flip side, air adds around 20% of oxygen to your wheels, which speeds up a tire’s rot and corrosion processes.
In over 7 million miles of testing, nitrogen was found to help tires last up to 50% longer, and fail 75% less often. Nitrogen inflated tires were seen to increase a driver's fuel economy by up to 10%, as well as improve steering, handling, and braking.
In addition, one of the main issues with air-filled tires is their under-inflation rate. Under-inflated tires cause 250,000 accidents every year and are responsible for 90% of all tire blowouts. Nitrogen helps with all of these issues by keeping tires at the correct pressure for longer.
