Anyone fill their tires with nitrogen?

i have been using it for about 1.5years now. you will notice a better ride and probably gain 1/mpg when you do it. your tires also don't have to be balanced all the time like with regular air in the tires. and it doesn't leak as fast as reg air also. its worth it to get it.

If any of that were true, the car makers would use it. Particularly if they could get a better ride and 1 more mile per gallon.
It's not worth it on a street car at all, actually.
It's nothing but a gimmick for a street car.

Sigh.
It doesn't make any difference whether you have filled your tires with nitrogen or air. Both will follow the Natural Gas Law, changing pressure (and a bit of volume since they are restrained by a tire) with changes in temperature at the same rate.
Gas Law, about 1/2 way down the page
By the way, I have a degree in Chemistry.
Don't waste your money. :beer:

Tires aren't balanced because of the type of air in the tires...
Could you please explain the mechanism by which oxygen leaks out faster than nitrogen, since that's the majority of difference between regular air and nitrogen only?
1 mile per gallon is HUGE! Automakers are under pressure to improve gas mileage. It's a shame that their engineers are so smart, yet haven't figure out that they can get a 5% mileage boost by switching to nitrogen in the tires.

Not that I don't believe that you have a degree in Chemistry, but you must be pretty rusty in gasses.
A. It's the Ideal Gas Law, not the natural gas law
B. Neither oxygen nor nitrogen are "ideal" gasses. "Ideal" gasses are hypothetical. However, the "law" works sufficiently well for both Nitrogen and Oxygen over the range of temperatures and pressures that would be experienced in a typical car tire.
LOL either shens or you got ripped off for those crappy tires on that equally POS mobile. LOL at anyone putting $500 tuires on that car (and from what I can see I doubt they are 500 each)
Either way I have actual performance tires, Goodyear Eagle F1 GS3's, and I fill em with air, and so does everyone else who takes their car to the track or drag strip. Gimic if you ask me.
Right. They are sending in a mixture of ~79% Nitrogen, ~21% Oxygen.
Someone asked about the mechanism that causes Nitrogen to leak out slower than Oxygen. I don't have any numbers here for rubber, but nitrogen and oxygen generally have different permeation characteristics and rubber probably has different permeabilities for both. If rubber is more permeable to oxygen than nitrogen, then it'd leak faster. Any permeation work I've ever done is on PET, and I can't seem to dig up numbers for oxygen vs nitrogen in that case.
One benefit to nitrogen tires is since there is no oxygen on the inside, there won't be any oxidative degradation of the rubber. I'm not sure if this is really significant or not, especially since the exterior of your tires is in contact with air all the time and will degrade anyway.
Like I said in my post, the reason we use nitrogen in our race car's tires is because we can control what we are using. When you use an air compressor to fill your tires the moisture content of the air you put in will vary depending on how humid it is. The difference in moisture content makes a difference in how quickly and how much air pressure a tire gains through a run. With nitrogen we don't have that problem because it's always 100% nitrogen moisture free. We could accomplish pretty much the same thing with an air compressor with an air dryer, but that's a pain in the rear.

Actually if you want to get technical nitrogen is made up of a carbon atom and a helium atom (technicly a proton) that fuse to become nitrogen 13 that decays to carbon 13 that then gains another proton to become nitrogen 14. Then all is right with the world until another proton gets in the way (damnit!) and oxygen 15 rears its ugly head!
Ok, too geeky. Sorry.

largely a waste of money, according to my buddy who owns a tire shop. won't stop him from asking if you want it though 😉
