john510 Posted November 19, 2016 Report Share Posted November 19, 2016 I never saw the need to put nitrogen in a car tire when i get as many miles out of it than the warranty covers. 1 Quote Link to comment
Dolomite Posted November 19, 2016 Report Share Posted November 19, 2016 I'm wondering why the hell Nissan would use it in the GTR if its such bullshit. A shit ton of r&d went into that car, I wonder what their reasoning is. 1 Quote Link to comment

datzenmike Posted November 19, 2016 Author Report Share Posted November 19, 2016 I like how air is 79% free nitrogen to begin with. How nitrogen molecules are smaller than oxygen so how do they not leak out through the rubber slower. How nitrogen tires (all four) are 6 grams (2 ping pong balls) lighter than air filled ones. That nitrogen and ordinary air expand about the same when heated. 1 Quote Link to comment
Trophy24 Posted November 19, 2016 Report Share Posted November 19, 2016 I had some guys cold call and try to sell me a nitrogen system for our shop. I was polite to them 1 Quote Link to comment
Ooph! Posted November 20, 2016 Report Share Posted November 20, 2016 Costco uses it here in my area and there is no up charge. My experience with it is from racing and it was used specifically because it is dry, so when heated the pressure does not rise as much as when using air and the moisture that is in it. My bottom line is I would use it at the track but on personal vehicles I wouldn't pay extra for it. 2 Quote Link to comment
datzenmike Posted November 20, 2016 Author Report Share Posted November 20, 2016 I imagine track tires heat to higher 'degree'. Car tires barely get warm, I mean just barely. Any slight difference is minimal. F-1 tires get to 300 F. 1/4 mile tires melt. 1 Quote Link to comment
MikeRL411 Posted November 20, 2016 Report Share Posted November 20, 2016 "Dry" Nitrogen has no moisture, so the interior rubber surfaces of the tire [or God forbid the inner tube if you remember what they were] will not rot as if it was exposed to moisture and heat, With today's blends of synthetic rubber I do not believe that this advantage is as significant as it was when I ran my 1955 Chevy! Yes, we knew of the advantages of a Dry Nitrogen fill way back in the dark ages, especially if you "inadvertently" got into an impromptu drag race. Especially for the pinks. Or if you were a cab driver. 1 Quote Link to comment
difrangia Posted November 20, 2016 Report Share Posted November 20, 2016 Nitrogen; useful in the handling, preservation, and serving of wine. "Sure, dear, I'll have a glass of wine. Be right back, I gotta go air-up the tires on my truk". Steve 1 Quote Link to comment
DanielC Posted November 20, 2016 Report Share Posted November 20, 2016 Nitrogen was used in airplane tires, because water would sometimes condense out of the air in the tire, and at altitude, run to the bottom of the tire, and then freeze. This chunk of ice would then take the tire out of balance, because the tire is not spinning until it hits the runway. So, if nitrogen was needed in an airplane tire, it must be necessary for your car, and it is a advertising advantage for shops that have systems to use nitrogen. 1 Quote Link to comment

But just like my single master cylinder '64 Dodge, we lived in spite of those tires. The hot tire for '69 was the Goodyear fiberglass raised letter tire. They were standard on my '70 Dart 340 and I survived going a buck fifty on them... shake my head now. When my new '76 B-210 needed new rubber bands I bought radials. The difference was night and day. 1 Quote Link to comment

datzenmike Posted November 24, 2016 Author Report Share Posted November 24, 2016 50 year old tires? I should hope so. Likely they were nylon bias ply and not even radial ply. 1 Quote Link to comment

When my new '76 B-210 needed new rubber bands I bought radials. The difference was night and day. In 1960 I equipped my 1955 Chevy Bel Aire 2 door sedan with a very [for that time] unique set of tires. They were radials, steel belted, and designed for New York City taxi cabs. Straight cut grooves and fine cross "sipes" tread cuts for traction on wet or crappy ground. Got them through a friend who was a cabbie. Drove across the USA and shipped the car to Japan. Drove on atrocious perhaps gravel roads all around the Kanto area for 3 years. Finally sold it in Japan, all lookie loos thought i had four new tires on the car. 1 Quote Link to comment
az_rat210 Posted December 11, 2016 Report Share Posted December 11, 2016 Link I found explaining the nitrogen thing. http://www.getnitrogen.org/pdf/graham.pdf Even after reading this and some other sites, the difference is only a matter of grams. I could see where over a long period of time this could make a difference cost wise on the rolling mass of an 18 wheeler. But on standard cars I do not seeing it making a significant difference. I did note where a someone posted testing this out with a large truck tire, for a differential result of 4-5 lbs on the tire. But again we are are talking large rolling mass vs your standard 15" car wheel. It was an interesting subject to research. Thanks for starting this topic. 1 Quote Link to comment

The more I learn about tires today, the more I wonder just how I lived thru the shit I did on Bias-plies in the 70's.According to the stats, I shouldn't have. 1 Quote Link to comment
