I recently went to get an oil change and they did the regfular check tire pressure stuff. one was low so he asked if id like it to be filled with nitrogen or air he said he could do all the tires in nitrogen. this was the first ive ever herd of it. is there any real benifits any one done this and noticed anything?

I read up a little on it and they said it last alot longer cuz the molocules are bigger than air so they dont seep out like air does.

Any input would be cool.

BTW he said its 2 dollars per tire its cheap but if its not worth it id rather get free air from local gas station

I remember reading that nitrogen helps with tire temperature and pressure dispersion throughout the tire, but I'm sure someone else on here can elaborate on that.

are you sure he wasn't joking with you?
yeah, bump on some info! i never heard of that before.

I know nascar and other motorsports use nitrogen in their tires.

nitrogen has larger molecules, so its harder for them to escape the tire over time. so a slower loss in pressure.
umm its also moisture free, therefore less corrosion on your tire and wheel.
also think about nitrous for your engine it cools things down, thereforeit would also allow your tires to run cooler therefore longer life.

ive heard about this also. But i heard about it from a old lady at work. so i dont know if they were just trying to make some money on her.

lsjon

As i stated it nothing new to motorsports, but is now available at dealerships, and some mom and pops gas stations.

a2dadamm

its def a real thing and some places are starting to offer it places like expressway or what ever. i might do it but ill def watch him to make sure he doesent just take my 8 bucks and leave reg air in my tires.ll but yah if nascar does it ill proly do it . lol

I want Nos filled tyres!!

I worked at a tire shop that offer nitrogen for our customers. The rumor of bigger mulocules is true. and yeah it is supposed to slow down on the amount of pressure loss. However in my expericance i have to refill the nitrogen tires as much as the regular tires filled with air. so i think it is garbage as far as that is concerned howeve i have also heard that it wont corroed rims as bad. I do not have an answer on that i havent cared enough to pay attention. And not to sound like a smart *** i don't even know why i know this but the air we breath is already like 75% nitrogen. i don't know its up to you guys though thats just what i know.

seabass10369

nitrogen will in theory make a difference, some of its attributes are less dense and larger molecule size than say oxygen. however this difference will be minute since differences between nitrogen and oxygen are small. and dont forget atmosphere is comprised of about 78% nitrogen, 20% oxy and a few other elements so air is mostly nitrogen to begin with so is the 8 dollars worth it thats up to you

elmo908

I think having a green cap on the tire air valve is supposed to mean the tire has been filled with nitrogen just to add to the thread.

elmo908

I believe that nitrogen is 7 on the periodic table and oxygen is 8, therefore making it smaller in size, making it more dense because more can be packed in the same space than oxygen. I don't know the molecular mass off the top of my head but I believe some of the facts in this thread are incorrect.

elements on the periodic table are arranged according to their molecular mass not atomic radii.

atomic radius of N is 65 pm and for O 60 pm. therefore N is larger

seabass10369

you can also observe this using PV=nRT

in this case (your tire) keeping P,V,T constant.

n(of N)*R=n(of O)*R

R(of O) being 0.3353
R(of N) being 0.3830

solving per unit this gives you .875 moles of Nitrogen to accomplish the same as 1 mole of Oxygen

lmao..............didnt want to start a science war with al this periodic table and this =12and u+me equals a good time lol just wanted to know if there was a big diff. lol
Thanks for your input tho sum smart ****'s on here lol
peace

I almost remember reading about nitrogen filled tires on a gas saving website. I think they said something along the lines of it weighing less.. taking less "power" to turn them from a dead stop.. Increasing gas mileage.

Not sure how much of it was bullshit or not..

Just thought Id throw my .02 in

i heard that in a race when your tires start to get hot, ur tire pressure will remain the same and won't increase with nitrogen in ur tires.

Ditto. Wtf does nitrogen have to do with cooling in your tires??

For $8 you're not going to notice anything except maybe your wallet is lighter. Standard air at a gas station is free so who cares that you need to fill up every 30 days instead of every 25.

And as a friendly reminder to those of you with "I'm not speeding, I'm qualifying!" bumper stickers, driving to work isn't Nascar.

Any gas will expand when heated. Basic physics.

Heres what Amer Honda has to say:

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.

Phew, lots of good sounding sentences to basically reaffirm that it's a bunch of bull.

x2 ... just came from chemistry class molecular mass is 14.007 for nitrogen and 15.999 for oxygen... just throwin that out there lol probably sounds like a freaking nerd

romJones

this has actually been researched before in multiple threads
but i guess ish startn to become a popular topic
in short...
nitrogen offers a couple benefits: (cliff notes version)

* Increased Fuel Efficiency – Correct tire pressure keeps the manufacturer's recommended “contact patch” on the road.

* Longer Tire Life – When it comes in contact with other materials, oxygen causes oxidation. Oxidation can make rubber brittle and cause it to lose tensile strength.

* Increased Safety – Under-inflated tires cause 90% of blowouts. Nitrogen provides more reliable pressure for reduced blowout potential.

* Improved TPMS Performance – If you have a new car, you likely are plagued by a flashing light telling you your tire pressure is low.

* More Predictable Pressure Fluctuation – NASCAR teams use nitrogen so they can more accurately predict tire pressure fluctuation.

* Longer Rim Life – Rim rust caused by condensation from water vapor and other gases can get caught in valves and create slow leaks in tires. Nitrogen is completely dry, so it eliminates the potential for condensation.


here is a website dedicated to nitrogen tire inflation
[ http://www.getnitrogen.org/why/index.php ]

my personal experience...
it DOES work
i'm filling less air between rotations!


where can u get nitrogen for free?!?!?!
* if your a costco member, u can actually have them filled at your costco
* costco has been using nitrogen for a little over 2 yrs now (& prolly the ONLY big company doing so right now)
* just pull up to the tire center and request nitrogen in your tires!!!

smileycvc

If you have a Costco membership (doubt many people on this site do) You can get all your tires converted to nitrogen for free. There have been test showing that it can benefit tire wear, heat, and keeping the air in your tires longer. Unfortunatlly, you cant get nitrogen at gas stations, so refills are a little harder.
