Excellent post on the subject (I didn't want to quote the entire long post, but figured the above pretty much sums it up).

And yet there are still people who will ignore the facts, argue with you because you haven't used it yourself, or just simply don't want to listen to science and facts because it conflicts with their beliefs.

Another reason to have nitrogen bottle is that when you go to the track you have a source of air to operate air tools. It cost about $35 to fill a big bottle.

Any kind of compressed gas bottle is a bad choice for that as it won't last very long. For filling tires when four wheeling and using air tools we use this:



It's small, filled with liquid CO2 which lasts forever when it's turned into gas and bottle fill costs $10 or so.

I put Nitrogen on my lawn. It works!

I did notice that your lawn is cooler and isn't leaking

Right on!

Maybe its the moderate temperature here, tires with Nitrogen filled are almost maintenance free - twice a year, at the most.

On my other car and motorcycle, monthly topped off with compressed air.

Yea, Costco here is great and they let me do my own refills.

Tires filled with dry air are about equally "maintenance-free" when you live in an area with temperatures that fluctuate minimally, with a difference of only ~0.2 PSI additional loss per month.

Try living somewhere with seasons and you'll need to drop or increase the cold tire inflation pressure every month or so even if you use nitrogen because the temperature changes have the exact same effect.

Even if you lose all of the ~21% that isn't nitrogen, and then refill with dry air, the result is a mixture in your tire which is 95.6% nitrogen. This point is hit after a total loss of about 10 PSI over time, without ever having done a nitrogen fill.

I got no problem at all spending 5 minutes a month adding 2-3#'s of air in each tire. BFD.

Doesn't look like many minds are going to change here!

Tim, people everywhere are the same, like to talk, all think they've got the right answer - right or wrong - whether they have actual experience or not.

I do like one thing you said to me once "lets agree on being disagree".

timd38

I guess I could agree with both sides on this. Would I pay to have nitrogen put in my tires, no, but I do put in because I have a bottle in my garage that I take the track. My last bottle lasted 10 years before I had to have it filled.

Back in the 90's my daughters raced karts and I needed a source of air for the air tools and that is what got me started on it and I just keep refilling the bottle.

How many people have ever heard this from a mechanic:

"...now if you had only used Nitrogen, this wouldn't cost you so much money to fix..."

victorf

If I had to go out of my way to get Nitrogen, well...

But Costco is less than a mile from my house and free.

And after several years of dependable result, consistent repeated side by side comparison with compressed air fills, Nitrogen is without a doubt.

I asked Costco if they would charge up my spare tank w/Nitrogen, that, they would not. I am too cheap to buy Nitrogen for conversion. My other car use non stock sized tires and Costco will not sell/install non stock sized or motorcycle tires, so I couldn't get away from more maintenance with my other car and motorcycle.

No moisture and minimal thermal expansion. If you have access to it no reason not to use it. Most aircraft tires use it for just those two reasons.

Once again I will add to what Vic has stated....If Nitrogen is close, handy, free and convenient....go for it.....If it it is not close, not handy, not free and not convenient...then don't use it....but one always has the personal choice to go for it...and everyone certainly can have their opinion... it does no harm....so users go for it....non users peace.......but I will admit there are some pretty savy posts on the subject....and even some good chemistry lessions......BUT IT ALL BOILS DOWN TO PERSONAL PREFERENCE....and that my friends will not change too many minds.....

VET4LES

It's free and I have never had a problem with it.

Scissors

False.

Aircraft with braked tires use nitrogen because an FAA Airworthiness Directive says to use it. That directive was enacted because during certain very-high-heat situations (which virtually no automobile will ever encounter) the oxygen reacts with volatile gases given off by the overheated tire, resulting in a fire.

But, then, what do Boeing and the FAA know?

PatriotZ

Good point scissors....and I like your thought process.....but again I will defer to my post #55....no harm and no foul
