Nitrogen on Tires
In July I swithced to Nitrogen on all my wheels instead of comressed air, pumped 29 front and 32 psi on rear wheels. This morning I checked it and it's still 29 and 32. I think its better than air. Any comments?????

Inert gases are fine for aircraft, I don't see why go through the trouble for a car. I have yet to encounter corrosion problems or volatility issues that would warrant the use of Nitrogen with any of my vehicles and they all have alloy wheels.

I think nitrogen is a good choice. I haven't used it but in looking at the chemistry of the gas...it is more stable with regard to temp changes and I THINK the N molecule as a stand alone is smaller than air and better suited for use where leakage is a consideration.
I am a Fire Protection contractor and we use N for a supervisory gas and for testing in our high end systems as opposed to air because of it's stability.
Tire pressure has always been an important part of automotive performance and in high end applications Nitrogen is a better choice. Now, finding it becomes another issue.

Air isn't free at a lot of gas stations up here. SoBs charge $.50 to run the compressor for 3 minutes. Sux even more when the hose is too short to get all 4 tires in one shot.
Damn, I hate that!

The N fillup will probably last as long as regular air but when you need to add a few lbs, you need to go back to the N dealer. Adding compressed air will defeat the purpose. No known side effects.

I have read that in racing applications and in military as well as commercial civilian aircraft that it's used regularly, mainly due to it's temperature stability.
I have a couple of Nitrogen cylinders that I keep at my shop for testing....maybe I should put a regulator on them and sell this stuff out the back door. Let's see, I think each one holds about 1800 cu ft at 3000 psi so at $3~$ a tire..... the profit margin would be tremendous!!!

BTW, how is N a larger molecule than O or CO2? It's atomic radius is the smallest of the 3 though not by much compared to O. However, O is not normally found alone in the wild so O2 is much bigger. Or am I not seeing something here?

We use nitrogen for all of our jets tires because of the moisture that can be found in regular air. At high altitudes (30,000ft.) the outside temperature is approx. -57C and any moisture in the tires will cause it to freeze of course. That is really the only benefit of Nitrogen. I wouldn't think it would make any difference on cars, just another way for someone to make a few bucks. Save your money, use free air
