Who uses Nitrogen to fill tires today?
• Race Cars:All racing cars and motorcycles use Nitrogen to more accurately monitor tire pressure and to eliminate the explosive properties of oxygen. • Commercial Airlines/U.S. Military Aircraft:The Federal Aviation Administration (FAA) requires Nitrogen in aircraft tires because it reduces the potential for water vapor freezing at high altitudes and decreases the potential for explosions. • Fleets and Passenger Cars: Nitrogen tire filling is quickly becoming accepted around the world for passenger cars and truck fleets. Do you still need to check the pressure on Nitrogen-filled tires regularly or refill them? While Nitrogen will help maintain proper tire pressure longer and will remain more constant over temperature changes than typical compressed air, you still need to check your tire pressure on a regular basis as recommended by the manufacturer. Although the need to refill the tires should be less frequent, you should still refill your tires when they go below the level recommende
