You have to go to a special tire place to get it, but you can save time by
just tossing a few $10 bills down the gutter.
In theory I can see where the larger nitrogen molecule would be better than
the smaller oxygen molecule, but since air is mostly nitrogen anyway, I'll
be damned if I'm going to pay a premium to get ride of hte other 20%.
Interesting, but have you actually experienced such situations? Have you
ever had a tire go bad from the inside from oxidation? I've gotten as much
as 70k miles from tires, but they were still OK inside, the tread was, as
Moisture? Never seemed to be a problem either. They state that
compressing the air concentrates the humidity. True, but most is left behind
in the compressor tank and drained out.
Explosions? Ever had a tire explode in flames? They state nitrogen reduces
the possibility, but while that is true, how many car started on fire from

Good points, Ed. I just provided the link. :-)
I have heard Pat Goss (Goss' Garage segment on Motorweek on PBS) recommend
nitrogen in tires, and I respect his opinion as a master mechanic.
People on TV recommend a lot of things that aren't necessary. The
advantages of nitrogen for passenger car and light truck use simply
doesn't outweigh the costs in both money and energy. It takes energy to
extract 96% pure nitrogen from air. This is simply energy that doesn't
need to be wasted for this application.
I pretty much do too, but sometimes they are being subsidized by some of the
products mentioned on the DIY shows. This Old House is a perfect example.
One company ( a customer of ours) offered to give them product to build a
house, value about $15,000. They said yes, if you also give us $18,000
Pat Goss's recommendations are paid for by the manufacturer of the product.
Take a closer listen to the show. You'll see it's quite a bit about
selling product and not so much about answering questions.
Yes, there are places where N2 use is warranted such as aircraft and
heavy equipment where extremes of temperature are encountered, but for
normal passenger car tires this is simply addressing problems that
aren't a factor. Check your air pressure once a month (which you should
do even with N2 as leaks can develop other than through diffusion) and
you have nothing to worry about.
Nothing is free. You just didn't pay for it explicitly. :-)
I think most of what is said about Nitrogen is true, it just isn't
terribly relevant for passenger car use. It certainly won't hurt
anything, but it isn't going to change much.
Although, I had to laugh as after reading this thread I heard an
advertisement on the radio today from a tire dealer advertising 99.7%
pure nitrogen for your tires for something like $10 a tire. The
hilarious part is that they claimed that this could save you up to
$134/year! I don't see how these people can rip people off and outright
like like this and still sleep at night.
