I had to get two new tires(non z car,jfi)! New tires on the rear, old tires (but good tread) moved to the front. Rear new tires, were nitrogen filled(free, no charge, I didn't even request it).
That was 2 months ago, I check the pressure on the 1st of each month faithfully!
The front tires, I have had to add a pound or two of air each time. The rear nitrogen tires have maintained the same pressure.

I use Nitrogen, but I don't inhale!

A ten second Google search isn't scourer. I deal with technicians all day everyday...who cares that your a tech. Your probably a shadetree tech anyway since your on these forums. You not an engineer that developed anything, so what good is your word against all these organizations and manufacturers who promote Nitrogen. That's my point!!

If you want to state your opinion then that's ok!! I keep repeating myself about first hand experience and nobody states that they've tried it and it didn't make some difference. No real comparison study. That's my basis for arguement. Not that I am a pro and you should listen to me!!!! :icon14:

Bottom line, you can listen to folks who sit in front of a computer and analyze things and make generalized statements when a legitimate question is asked or you can listen to first hand experience w/ actual comparisons.(based on initial skepticism)

DONE! You'll be happy to know I'm done here! I'm sure you'll need the last word! :rolleyes:

panties in a bunch much, jeez. you contradicted yourself anyway. my statements come from actual experience and whether you choose to believe it or not is your prerogative. this isnt some college class where i have to APA cite every damn statement i make.

now that he's gone, back to the topic. i guess the moral of the story with nitrogen is if you feel it is worth your money, go for it, if not, don't. just be aware that there is much hype surrounding this stuff.

nitrogen sucks every new car i have ever bought had nitrogen. shi t flattens quick within a few days. and I was told its better then regular air. yahhhhh right..

Who cares? What can your car do on the track is what I care about.

The air I breathe has worked for me for 40 years. I check my tires for pressure about once a month on 3 cars and 2 bikes. Most times the air pressure hasn't dropped enough to show up on my guage. If it has dropped, I flash up my compressor and add the required amount. On one ocassion, I had new tires filled with nitrogen. Those tires lost pressure over time just like they were filled with the air that I breathe. Did I get ripped off? I don't know of any way to check if the tire actually has nitrogen or not. Is there an easy way?

My wheels (on my car) sat all winter and didn't lose any pressure at all with regular air when measured at equal temperature. According to my "tire guy" most of the pressure loss occurs as the rims get a few years older and oxidation occurs on the surface of the aluminum preventing a perfect seal. There are various methods to fix this during a tire swap, but only the good shops seem to bother. Of course there are plenty of other ways to lose air pressure such as leaky valve cores, hidden punctures etc. Also note that using a tank air compressor with water trap filter will give better results than a portable tankless compressor.

yes, perfectly said:tup:

Decreases rolling resistance...lol...

JUst like everything in JC Whitney adds 5HP and 10% better MPG.

This made me laugh, not sure if anyone else got the joke?:bowrofl:

The rear nitrogen tires have maintained the same pressure. Checked today, refer to post46.

I don't know what people mean when they say N is more stable.

Remembering high school physics: P1T1 = P2T2. (Correction? P1/T1 = P2/T2). In other words, you heat a gas up a certain amount then the pressure goes up a certain amount. Doesn't matter what gas you're talking about. Maybe they mean no Oxygen is safer and better (uh, less oxidation). Ya, I'll buy that.

Anyways, I just bought a Coupe w/Sport pkg today (yahoo!), and it has green caps on the valve stems. Does that mean they put Nitrogen in the tires, or are they just pretty green caps?

Hahahaha ya I did
