Nitrogen Versus Compressed Air In Your Tires

Nitrogen is Earth’s most abundant gas. In place of compressed air, can it benefit your tires to help them perform better, last longer, or increase fuel mileage? Air is comprised of approximately 78 percent nitrogen, 21 percent oxygen, and 1 percent of 13 other gases. It also contains, on average, 1-3 percent of water vapor. So is it worth eliminating the 22 percent of the other gases? My research revealed the nitrogen molecule has a more difficult time migrating through the rubber compound than air does. The other benefit is that nitrogen pressure does not fluctuate as much as regular compressed air with temperature changes. This is good because tire pressure can change as much as 1 psi for every 10 degrees in temperature variation with compressed air. The biggest benefit is that through the course of removing the other air molecules, it also removes most of the water vapor. This is key, as water vapor in your tire can cause more of a pressure swing than dry air and promote mor ... read more
