Does anyone know if nitrogen in tires causes a different feel, is handling affected? Do the tires corner the same?

The reason i ask, i recently purchased new tires, same tires as i had before, i noticed that while driving on the freeway i get a floating feeling, now i know my struts were bad so i put new factory struts on the front, but i still get the same feeling. The only thing i did different between this set of tires is use nitrogen.

Atmospheric air is just under four-fifths nitrogen. Almost all of the remaining fifth of air is oxygen, which has similar pneumatic characteristics to nitrogen.

There are arguments to be made for nitrogen fill, but you would have to be uber-sensitive to notice any difference in handling.

Yeah i just got done reading a huge article on nitrogen in tires, not really worth it.

^Understatement.

I fill mine with 78% nitrogen, and it's fine.

I have access to 100% nitrogen, but I can't figure out how to properly fill up the tires with it, since I can't drain all the air out of the tire all at once.

To properly do it, a wheel needs two vavle stems. One to fill and one to purge as you fill.

Which, I had no idea why my wheels had two stems until about 3-4 months ago.

Nitrogen filled tires, only a few dollars extra. What a bunch of marketing Horse Manure. Please, no one realy falls for this, do they?

Some one fell for it.

I treated my lawn with nitrogen last month and it looks really lush and green. Probably a better use for the stuff.

When I got my new tires, they asked if I wanted nitrogen fill for no extra charge, so I said sure why not. I honestly can't tell much of a difference. The car rides smoother, but I think that is just the new tires talking.

Hate to be the one to ask, and i've searched around for an answer with no luck, but, my Mazda6 came with nitrogen in the tires. Can I add just regular air to them when needed?

Yes

The air you breath is 80% Nitrogen (N₂) to begin with. It makes no difference. Its a gimmick.

Nitrogen is awesome here in alaska for the cold temps. it keeps your pressure from changing with extreme temps.

Down here in the Lower 48, our oxygen (which comprises about a fifth of the air in our tires) behaves, so far as expansion and contraction as a function of temperature is concerned, very much like our nitrogen (which comprises almost four-fifths of the air in our tires). Is Alaskan nitrogen that different from Lower 48 nitrogen, or is it the oxygen up there that is different?

Haha

pretty sure it doesn't get anywhere near -65 down there. but nice try, its good for when you are out and driving then come home and put your car in the garage. Nitrogen doesn't expand and compress like oxygen, sounds like your not as smart as you thought you were. if you fill it to 45psi outside at -45 and then park it in the garage the air expands, then you now have more air pressure in your tire which is a problem. now you have to let some out because you drive outside and now the air in the tires is warm, then it cools down, now you low pressure.

They also use nitrogen in Paintball because it doesn't get weaker with temp, or when it gets low. it keeps pressurized.

I win.

Why doesn't nitrogen expand and contract with temperature? Don't all gases follow (or at least approximate) the ideal gas law:
PV = nRT

Nitrogen is magical. If you question that there is no hope for you. I have inflated my car seats with nitrogen, and Xzibit heard I like nitrogen, so he put nitrogen in my nitrogen so I can zoom zoom while I zoom zoom boom.

Air is 80% Nitrogen anyway so there is little benefit to using nitrogen filled anything especially when you fill up with low humidity. What is going to expand/contract with temps is the water in the air, not the N2/O2/CO2.

Well, with Nitrogen filled tires, you can say "I don't have ANY 'Air' in my tires",
and not be lying....whoop ti doooo.

no no it does expand and compress, just not with as much variation as oxygen.

The biggest bonus is you don't get all the moisture from an air compressor that hasn't been drained in a month. Nitrogen's volume changes with tempurature just like any other gas.

oh well I guess I don't know then. all I know is it works great at negative temps and regular air doesn't.
with air in my tires my car gets flat spots if left outside. with nitrogen it doesn't, because its not losing any pressure but oh well. Whatever. lol so with that I will leave this post.

Propane is also used in Paintball and Airsoft guns. Everyone should fill their tires with propane then, since its way better than nitrogen. It actually gives you an extra 25hp, just like if you put a "JDM" or "Type R" sticker on your car.


No offense, but if any amount of pressurized gas in a canister 'gets low'...how exactly does it stay pressurized more than any other molecule? o.O Where I came from, if you have a 50psi bottle of nitrogen, and a 50psi bottle of oxygen, and you release enough to reduce it 30psi, there is still 20psi left...no matter what gas is in there.

I can't disprove how nitrogen acts with high or low temp extremes, but I'm going to put propane in my tires tonight, because nitrogen stays pressurized and propane is also used in paintball. who's with me?!!?
