PROS: Using nitrogen instead of compressed air has distinct advantages, which lead to immediate benefits. It has more mass, so it migrates through the tire three to four times slower. The result: Tires hold their psi longer. It runs about 20% cooler. Less heat results in less tire degradation. It drastically reduces oxidation on the rim and inner-liner (nitrogen systems almost totally eliminate oxygen -- the cause of oxidation -- from the mix). It is environmentally safe. CONS: Look for the CTE's (Coefficient of Thermal Expansion) for N2 and regular air, and Thermal Conductivity properties. There won't be much difference, as air is ~78% nitrogen anyway.
The Diatomic Radii of N2 & O2 * N2 = 1.4 Å
* O2 = 1.32 Å So... Diatomic Nitrogen is 0.08 angstroms larger than O2. And again... air is only ~21% Oxygen. Therefore, the migration theory really doesn't seem to hold much water. Nitrogen - Atomic Mass 14 vs Oxygen - Atomic Mass 16
So where does the Nitrogen get more mass?? How is Nitrogen on the inside of the tire (which is relatively immune from wear) going to reduce Oxidation, when the exterior of the tire is exposed to the atmosphere (~21% Oxygen; ~78% Nitrogen) RESULT: Anybodys guess!

A Question for Dads This recent topic from the Tractor Talk discussion board is being highlighted because it is an awesome display of the caliber of individuals that have made this site their own. The young person asking questions received positive feedback and advice from total strangers who "told it like it is" with the care many reserve for their own kids. The advice is timeless... so although it isn't necessarily antique tractor related, it will be prominently displayed in our archives to honor those who have the courage to ask and those who have the courage to respond in an honest, positive manner.
