so sexy it hurts |
I recently picked up a new car. It came with OEM tires but filled with nitrogen, and has a one year warranty on free nitro fillups. Supposedly, nitrogen is much more stable than atmospheric air, with less moisture being introduced into the tire, and less temperature-induced pressure variances. Can anyone confirm the legitimacy of this? Or is it just snake oil? Our air is already 78% nitrogen. "You have the right not to be killed..." The Clash, "Know Your Rights" | ||

In theory yes there is a slight benefit to filling with nitrogen as the molecules are slightly bigger so the tires will leak slower and the gas itself is inert. This is beneficial if your driving an F1 car... BUT for us mere mortals there is no practical difference. ------------------ Eddie Our Founding Fathers were men who understood that the right thing is not necessarily the written thing. -kkina | |||

That's what I figured. The salesman made a big deal out of it. I was just like, 'here's the bottom line, gimme the car for this price or I'm walkin.' " "You have the right not to be killed..." The Clash, "Know Your Rights" | |||

Remember our atmosphere is 78% nitrogen so how much does that other 22% really matter in day to day driving. _____________________________________ Because in the end, you won’t remember the time you spent working in the office or mowing your lawn. Climb that goddamn mountain. Jack Kerouac | |||

Depends. Normal day to day joe-shmoe duty, you will not notice a difference. But, in rapidly changing conditions when the tires are being thrashed to their limits, a nitro fill will be more stable and consistent WRT pressure changes from temperature swings, high level drivers can feel this. Having said that, I still use normal compressed air when at the track. When you race you should be monitoring tire pressure anyway, irregardless. I see the nitro thing as just another high performance application being twisted to squeeze money out of shmoes when they do their highly infrequent minimal maintenance. | |||

I believe that in extreme cold weather (like Alaska cold) nitrogen is preferred because it is temperature stable and inert. Not sure what benefit it would be outside of that environment. | |||

Costco has been filling with nitrogen for years, decades maybe, no extra charge. Luckily, I have enough willpower to control the driving ambition that rages within me. When you had the votes, we did things your way. Now, we have the votes and you will be doing things our way. This lesson in political reality from Lyndon B. Johnson "Some things are apparent. Where government moves in, community retreats, civil society disintegrates and our ability to control our own destiny atrophies. The result is: families under siege; war in the streets; unapologetic expropriation of property; the precipitous decline of the rule of law; the rapid rise of corruption; the loss of civility and the triumph of deceit. The result is a debased, debauched culture which finds moral depravity entertaining and virtue contemptible." - Justice Janice Rogers Brown | |||

really? I thought PV=nRT, no matter what the gas is. Straight nitrogen fill, depending on source, might exclude some water vapor, and that is probably helpful. But, if the fill is all "gas", whether N, O, He or dry air, I'd expect it to react to temperature changes the exact same as 78% N. NRA Life Member - "Fear God and Dreadnaught" | |||

great sales pitch sounds cool meaningless, and any benefit is absolutely imperceptible to us mere mortals if you were a mass spec looking at leaks, it may be important, but probably not. Air has 1% Argon which is inert as well.... hype [B] Against ALL enemies, foreign and DOMESTIC | |||

Perhaps for very demanding situations, straight N is a real benefit for vehicles. I do know when I worked at an airport, and helped the A&P mechanics do annuals, service work, or handled requests from customers to check their aircraft tires, we used super pure straight Nitrogen for all aircraft tires. ______________________________ Nitro smoke rewards a long days toil... | |||

What kind of car? | |||

Here we go. Compressed air has a lot of dirt and moisture in it. Dirt and water are not gas. As the proportions vary, so can the pressure variance. Is it enough for a non F1 driver to notice? No. Im not advocating the service as you have read already. If you want to get more esoteric feel free though. It's fun to argue over minutiae for some people. | |||

if we are talking a street car it doesn't matter. At the track (or in your airplane) its a different story. Its mostly about moisture. A typical air system is filled with it and you don't want it in your tires. It's used lots in racing applications and I would recommend it in applications where tire temp or rise in tire temp is important (I race motorcycles, but the same applies for cars). “So in war, the way is to avoid what is strong, and strike at what is weak.” | |||

I fill my tires with helium. It's like riding on a cloud!  | |||
