Nitrogen in Tires

From what I've heard Nitrogen in the tires doesn't do s**t for you. He probably got the gain in MPG because he has been laying off it.

Actually filling your tires with Nitrogen is not a bad idea
1. Nitrogen is a inert gas which does not cause the rubber to breakdown as fast
2. Does not expand or contract as much as the other gases in air
3. Does not contain water, which is harmful to the rims and the rubber
Now is it worth ten bucks....I don't think so, and like the others have said if you keep your tires properly inflated your mileage and the life of your tires will remain constant Nitrogen or just plain old Air

Palm Beach County FL actually got a $350,000 grant from the US gov to test nitrogen in tires in their bus fleet over a multi-year period
Consumer's Reports magazine was initially very skeptical of this,
but in a test of tires mounted on a rack outside (not on real vehicles),
CR found that nitrogen leaked out of the tested tires slower than 'dry' air
I have not paid to have nitrogen in my tires
and prefer to wait to see what the official FL bus tire test finds
'Extraordinary Claims Require Extraordinary Proof'
is a wise saying
tank to tank MPG varies as much as 3 MPG
so your friend can be telling you what he believes to be true
and still be wrong about the 2 MPG gain with nitrogen in his tires,
or simply,
your friend just had one or more underinflated tires
that the nitrogen fill brought up to proper pressure
one thing is true from past testing:
even just a little water in the air fill of a tire is harmful
and as water goes from liquid to steam
there is a big pressure variation
