About Nitrogen...

Nitrogen is an inert, dry, non-flammable gas that’s used by NASCAR racers, the aircraft industry, the U.S. military, Formula One racers and others to inflate tires.

Benefits of nitrogen

• Better tire pressure retention -- nitrogen migrates through a tire 3 to 4 times slower than oxygen. It may take 6 months to lose 2 psi with nitrogen compared to less than a month with normal air.
  
• Improved fuel economy -- a result of having the proper air pressure which lessens the rolling resistance. Under-inflated tires have a greater rolling resistance.
  
  
• Cooler running tires -- tires inflated with nitrogen run cooler than tires inflated with regular air, to help extend the life of your tires.
  
  
• Removal of oxidation -- oxygen is a highly reactive element at high temperatures and pressures. Replacing the oxygen with nitrogen helps eliminate the oxidation that damages inner liners and belt packages in tires.
