Air is 79.1% nitrogen, 20% oxygen and the other 0.9% is water vapour, Co2 and small concentrations of noble gases such as neon and argon.
Q: Is there any advantage to using nitrogen instead of compressed air in my tyres? Will i notice improved fuel economy and a smother ride? Will my tyres last longer?
Yes, yes and yes!! There are several compelling reasons to use pure nitrogen in your tyres.
Reason #1: Accurate tyre pressure. Nitrogen is a larger molecule than air so is a lot less likely to migrate (permeate) through your tyre's rubber casing. This means your tyre pressure remains more accurate over its lifetime. This results in a consistent driving experience as when your tyres heat up and cool down, compressed air gains and losses up to 3 or 4 psi. Nitrogen is unaffected by temperature change.
Reason #2: Fuel savings. Because nitrogen is unable to permeate and is unaffected by temperature change, your tyre will never lose pressure - unless you get a puncture from some other hazard like a stone or nail. This will increase your fuel efficiency because the lower the pressure in a tyre the harder it is for your vehicle to turn it around. This is the law of friction!
Reason #3: Maintenance savings. Because nitrogen is so much more stable than compressed air, it helps your tyres to wear a lot more even over their lifetime. Slow leaks are also a lot less likely to occur as the nitrogen molecules are a lot larger than compressed air.
Reason #4: No corrosion. Everyone knows that oxygen causes oxidation – rust, rot or corrosion – but pure nitrogen does not have any oxygen in it at all. This makes it impossible for oxidation to occur inside your tyre & rim assembly. Hence no rust or corrosion around the inside of the valve stem, bead area or internal rim surface.
Reason #5: Improved handling. This is a result of the fact that nitrogen is a far more stable gas than compressed air. No more loss of pressure = safer and more controlled driving experience for you and your family.
