When all said and done it's not the nitrogen it's the water content. The
nitrogen filling is also a bit of a scam IF they don't vacuum the tire out as
well, as you are starting with a volume of already non dry air. You can get
the same effect with a dessicant dryer on your air compressor for the most
part. The main thing is that your tires stay a constant pressure which helps
with gas mileage a bit. Claims for longer tire life, yada yada yada. Bottom
line is check your tire pressure now and again ;) My favorite thing is the guy
gushing waterbased tire slop around the bead then saying you need this
nitrogen, the water moisture is the problem. Last claim was the nitrogen
molecule is larger and will leak less, this problem is again fixed by 'Check
air in tires now and again'.
Funny thing I think CostCo does it for free or a
couple of bucks now. The Volvo upsell might have been for the cool green caps
you get with the 'Nitro-fill' ;)

Nitrogen filled tire fad
The Volvo dealer convinced my wife that she should
convert our S-80 Volvo to nitrogen-filled tires. Dealerships certainly do need
service income when car sales are down.
Now the Volvo is set for competition
& the dealer is $50 richer. I doubt the Volvo has ever exceeded 70mph---and
that rarely--- with her driving. My new Mustang is said to have a 150mph top
speed, but makes do with ordinary air.
. Don't I recall that the atmosphere we
breathe is 80% nitrogen. Ah well---a Volvo with Ferrari asperations.
