I use a boutique blend that uses a centrifuge to spin up the air to make it faster. I get 10HP per tire more.

I'll bet you got that 10hp figure from the advertising.
If Porsche could gain 10 hp by using that boutique blend they would have....

I have a compressor in my garage set up specifically for 78% N. It has a water trap that has yet to ever have any water in it.
At 8% humidity here in AZ most the time, I'm not concerned about my TPMS sensors nor the inside of my wheels corroding.... Unless you're topping off with a garden hose, how much H20 is inside the tire?
Water doesn't corrode without O2 present - which is a more sustainable argument for N, not that there is one.

If you see a 7 lb pressure increase with Nitorgen in your tires, you probably have Winter Nitrogen, and need to change to Summer Nitrogen as soon as possible

I once tried Helium in my tires but it made my car sound funny.

Great line [I laughed out loud], but what about the unsprung weight savings? Surely good for a couple of ounces per tire.

You get PASM problems with Helium. And we know what happens if you use Hydrogen.

Tire guy mounts and pops bead with shop air. Pulls hose and lets all air out, fills with N to max tire pressure, again pulls hose off and lets most of the N and shop air mix out. Inflates to desired pressure with N. I keep a N cylinder in my autocross trailer just for that.

Basically, just wanted to say and maybe a for the whole thread coming up again.

As my own dollop of fuel on the fire, when they tell you a nitrogen fill protects the tire from oxidizing inside, you might think about the oxygen outside as mentioned, but you also might ask yourself how many years you expect those tires to survive on a car driven like ours. Of course, you might be working in an auto museum and be planning to seal the car in a purged atmosphere. In which case,

Incidentally, I suspect my tires are slightly higher in nitrogen than the outside atmosphere because our dealer does a 'free' nitrogen fill and that's who mounted the tires. I have noticed the transient response is improved on roads with rippling. (No I haven't. That was a lie. See? Full of hot air just talking about this.)

4 pages? Impossible.

My favorite thing about the nitrogen fill is the green "N2" caps that they put on after the fill.

The race teams use top tier nitrogen,that is the only kind that makes a difference,not street grade.

Fahrer

Here, the nitrogen can actually help in the form of amines as part of the detergent package in the fuel to keep th valves clean ( unless you have DI)

There always Nitrous. But that should only be used on roads with lots of curves.

I heard that there have been cases of cheap, Chinese nitrogen used instead of N rated Porsche approved...

I think I will put those green caps on my car for the bling factor.
