Regular air is 78% nitrogen, and air from a reliable compressor does not have a lot of moisture in it. Tires are designed for the 3-4 psi increase from cold to hot operating temperatures.
All the benefits of nitrogen in street tires are either theoretical or negligible - it's different in a racing tire where half a pound at extreme temps can make the difference.
Step back from the details and look at the big picture - the biggest single factor in the life and performance of street tires is correct pressure, regularly checked and adjusted by the owner.

 

I agree, in much the same way for most of us a good premium dino oil is good enough. While synthetics may have a marginal advantage under extreme conditions, regular maintenance is a bigger factor.

Knowing a 'reliable' source of air could be a problem. I woud think a well maintained small Craftsman, etc. at home is as good as any. And I believe there are in-line moisture traps/filters that can be used also.

But if N2 is readily available it does give you some margin. But even N2 compressors need regular maintenance I would presume.

 

You're right, people should get a handle on the basic maintenance that will solve 98% of their problems before they worry about the stuff that will address the other 2%.
It's amusing (in a twisted sort of way) when you see people splitting hairs arguing about the marginal benefits of some bolt-on or pour-in product, then they turn around and post something like this:

"My engine started to make a clunking noise - I only had 1 quart of oil left."
"The TPMS light came on going down the highway, so I pulled over and put air in the tires and it went out - but it came on again the next morning so I just ignored it."
"The light on the dash says 'Service Engine Soon' - what should I do?"
"Infiniti recommends premium gas - should I use regular?"

... and any post with the word "thingy" in it.



BTW - here's my source of reliable air:

 

...reduction of corrosion and the associated leaking is a big plus.

Is that REALLY a problem though? N2 will not help tread wear or keep a nail out.
My tires need some air maybe every 4 to 6 weeks (1 or 2 psi) not a big deal IMO.

 

That's my favorite. They believe most everything else in the manual but the fuel recommendation is a conspiracy! LOL

 

from what i understand making the swith to nitrogen isnt that easy. in order for it to be effective you have to completly remove the regular air you filled up with then fill with nitrogen. and it has to be done more than once to be sure you are getting all of the regular air out. otherwise the benifits are not relized. this is what a tech told me so i could be wrong.

 

True, It won't help tire wear,.. but reducing moisture in the tire will prevent corrosion in the wheels which will eventually lead to leakage. but that's all. (IMHO).

I can't count how many times I hear people complain about their "leaking cast rims"...... putting in N2 will all but eliminate that issue.

Might still be a problem on some cheap aftermarket rims. I can remember when leakage was more common but hardly ever hear about it these days.

Don't get me wrong, if an N2 dealer was convenient and did not charge much I might give it shot. I just don't think it's worth the time and effort to hunt one down, for me anyway.
