Dealership experience today...
ok sorry for a random thread but I had to bring in my TL for an alignment check today. They said i needed new front tires which i completely agree with because i know that the inside tread of the drivers side was practically bald. So after "making some calls" the service rep. told me that new tires would cost about $200+ for two brand new tires and they nromally don't cover tires....BUT...they said they'd be willing to cover the tires if i allowed them to use this new "nitrofill" system where they fill your tires up with a refined nitrogen instead of air which contains "wet oxygen"....would only cost me $9 to fill up each tire and I ....so $39+/- just for filling the tires with Nitro. + two brand new tires, i'd say is a pretty good deal...I don't know how much of what the rep told me was true but i'd rather pay the $40 for new tires + nitro then the full $200.... Maybe it has something to do with my firefighter license plate tag....i dunno but i'm a happy camper today..lol

Nitrogen (someone correct me if im wrong) has bigger molecules and is more stable than regular air. some Evo owners are putting that in their tires to get more consistent lap times. I think that is a good choice.

I believe nitrogen is used in race car tires because the tire pressure doesn't fluctuate as much with N2 as it does with regular ol' air. I'm not sure why, but you got the best of both worlds: 2 new tires and an N2 fill up.
BTW...you don't have to go back to the dealer for nitrogen...you can just fill up with regular air. Congratulations on your $20 tires!

www.whynitrofill.com supposedly race cars, nasa's shuttle, military applications.... and the tires cost $40 cuz they filled all four
I'm gonna play it safe and fill with only nitro. I registered my "nitro fill up" on that website i just gave and i guess i get:
* Free Roadside Assistance. (Details)
* Free NitroFill™ "Top-Offs" for the life of your tires.*
* Free pressure and purity tests for the life of your tires.*
* Free service reminders and money saving Newsletters via e-mail.

Yep, nitrogen molecules are larger than oxygen ones, hence less migration through the rubber. Remember however, that regular old air is about 78% nitrogen anyway. 100% nitrogen in tires is probably a good thing, but I wouldn't pay anything to have it put in.

I'm going to get the nitrogen when I have my Aspec rims next week. My TMPS was going crazy this morning. Last night was the first night of 40 degree weather here. The tires showed 26 and 27 for about 20 minutes until they warmed up. Once they warmed up showed 32 and 31. Over the summer when warm showed 37 and 36.
Nitrogen should stop these fluctuations.

there probably isn't much of a difference but i paid $40 for the fill up + 2 NEW tires so it worked out

Nitrogen in your tires does nothing that air cant. That is the reason why nitrogen is better is because it comes out of the tank very dry. Typically the air you fill your tires with has alot of moisture in it. (especially if you dont have a trap on your compressor) Its the moisture in the air which causes the changes in pressure. Otherwise nitrogen obeys the ideal gas law just like regular old air. If you want to try dry air, get it from a compressor designed for SCUBA. They are very good at removing the moisture from air.

Costco started filling their tires with nitrogen a few years ago. Just look at all the cars with the green wheel cap parked around the tire center.
Unfortunately, Costco refuses to touch aftermarket rims.. which makes me have second thoughts on getting anything but A-Specs.

Good expanation 'Geekbiker' and agreed 100%.
Speaking from the racers standpoint, there's always some pressure variance even when using Nitrogen, 1-In that you can never fully purge all of the oxygen out of the tire (even after several bleed-off, refill sessions...although it does make it better!)2-If some sort of lubricant was used to seat the tire, the resultant moisture was cause added pressure.
All of this amounts to being able to know how much of an increase you will see regularly, so that initial pressures can be set to give the optimum at running temperature.

LOL wow everyone was all over the nitrogen thing in this thread...i was more or less happy that i got two brand new tires at a really good discount IMO, the nitrofill thing was just a bonus

Good deal on the tires though.

Acura doesn't recommend Nitrogen in their tires....here's why (from the Sept 06 Service Bulletin)...

Nitrogen Inflation: What’s Our Position?
Surf any automobile tire-related website these
days, and you’ll likely see something mentioned
about nitrogen inflation. It’s becoming a hot topic.
We’ve gotten a number of inquiries lately
concerning American Honda’s position on this
practice.
When it comes to inflating automobile tires, it’s
our position that ordinary, dry compressed air
—
which is about
80 percent nitrogen already—is
the best choice. That’s because it’s more readily
available, and the benefits of using nitrogen
simply don’t appear to outweigh those of using
compressed air.
The practice of inflating tires with nitrogen really
isn’t anything new; it’s been around a long time.
It’s been commonly used on aerospace vehicles,
commercial and military aircraft, military vehicles,
race cars, and even heavy off-road construction
equipment. Here’s why:
• To meet rigid safety and performance specs,
the required tire inflation pressures are often
very high, especially in the aerospace industry.
The tire inflation pressure for NASA’s space
shuttle, for instance, is a whopping
315 psi!
• Nitrogen is an inert gas; it doesn’t combust or
oxidize.
• The process used to compress nitrogen
excludes water vapor. Water vapor can expand
if the temperature climbs above
212°F.
• Tires inflated with nitrogen leak slower over
time than those inflated with compressed air.
Automobile tires, on the other hand, are subjected
to an entirely different set of conditions. Here’s
why inflating tires with nitrogen offers no real
advantages:
• Although tires inflated with nitrogen leak
slower over time than those inflated with
compressed air, they still leak and need to be
reinflated to maintain proper pressure. If you
can’t find a place that offers nitrogen
inflation
—and there aren’t yet all that many
places that do
—your only option left is to
reinflate with compressed air. Doing that
drops the nitrogen purity.
• Nitrogen offers no better protection against
road hazards such as cuts and punctures. So
no matter what you inflate the tire with, you
still need to check the condition and pressure
of the tires at least once a month as
recommended in the O/M.
• Tires that are inflated with compressed air and
properly maintained offer the same fuel
economy, tread wear, and ride comfort as
those inflated with nitrogen.
• Nitrogen for automobile tires is produced by
nitrogen generators, which typically get about
95 percent
purity. But to actually get that
level of purity into an automobile tire, you
would have to deflate and inflate that tire with
nitrogen several times. If you’re not careful
doing this repeated deflation and inflation
process, the purity level winds up being closer
to
90 percent (compared to the approximate
80 percent
nitrogen already in compressed
air). Because of this, those claims of less
pressure loss with nitrogen aren’t valid.
So here’s the bottom line: Nitrogen is an ideal gas
for inflating tires in aircraft, military vehicles, race
cars, and heavy off-road equipment, but when it
comes to automobile tires, it offers no apparent
advantages over ordinary, dry compressed air.
Our advice to you: Just stick with the air you
breathe.

Thanks for the post. It's a reminder on basic science.
All the same, Darkness, your dealer gave you a great deal, enjoy the new tires!
