Default nitrogen in tires

I bought tires from Costco today since they had a good deal on 4
Michelin X-Radial DT tires in my size. It seems Costco only uses
nitrogen in their tires. I asked the man what happens if I want to to
put some more air in there later on and he told me it's no problem to
mix the nitrogen with the normal air. Is this true?

Well, BGM, since air is about 80% nitrogen at, I'd say you needn't lose
any sleep. ;-)

why must this dumb-ass question be asked so often? where the heck were
you guys in science class? did you even /have/ a science class???

air is 78% nitrogen.

tire "nitrogen" is only ~95%.

what do /you/ think going to happen if the two mix? spontaneous
explosion???

It is ok to mix "normal" compressed air with the nitrogen filled tires. I
do it all the time because I have a compressor at home and it is much more
convenient to top off the tires at home when they are stone cold than drive
to Costco.

You already have 80% nitrogen in normal air. So, there is no problem
with mixing 80% nitrogen (normal air) with 100% nitrogen.

I have no compressor, so I use a Schwinn bicycle-pump. About 8 strokes buys
me 1 psi.

All our tires get checked regularly, and I know their history, so I
usually only need to add a little bit for seasonal fluctuations.

Also it's good cardio exercise. :^)

I actually inflated a van tire from dead-flat to 32 psi once, with a
bicycle pump. Now /that/ was tiring (pun might be intended).

Whoa... that many strokes would probably have been a stroke for me ;-)

I really like having a compressor. Besides filling tires, having air tools
speeds up work quite a bit and air operated tools are lighter and less
expensive than a comparable electric one.

no, i just wonder where the **** educational standards are that allow
this kind of basic ignorance.

even if the op doesn't know, posting on usenet evidences an internet
connection. internet connection evidence access to a search engine.
access to a search engine indicates ability to to basic homework before
asking dumb-ass questions. the only possible exception to that could be
an educational issue in which the op was so poorly educated on basic
science, they wouldn't know where to look.

which brings me back to "where the heck was this guy in science class,
etc...".

Hi jim,

I was busy sleeping in class after drinking a bottle of whiskey. Jim
Beam was not one of my regular brands but I would take whatever was
available. It's a wonder I ever graduated from school and am now
involved in the Earth Sciences field. Don't piss me off again or I'll
use a laser from the satellite to zap your house in California!
