Great information Sandy.
The primary benefit is steady pressure given my climate. The severe drop in
temp can cause an already low tire to lose poundage to the extent the bead
breaks free resulting in a flat tire in a Northern Alberta temperature that
would cause many on this list to shudder (including me!). Yes, the tires were
new when they filled them, but I'm going to ask them about the water based
tire slop during mounting, which I'm sure is the case.

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' ;)

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.
