I'll have to look into it the next time I have the blinker fluid changed.

Hype...and I sell tires for a living.

My Hindenburg brand tires are filled exclusively with hydrogen.

I prefer Nitrous Oxide in my tires. When I am feeling down - a quick pull on the valve and I am ready to go.

Yeah, what type of car? My brother in law has a high-end Mustang that has nitrogen filled tires. I just can't imagine a salesman selling that nonsense for just a simple day to day driver though.

Tires will lose slightly less pressure with nitrogen fill. This matters if you only check tire pressure every year and a half or so. It also contains less moisture. This matters if you have cast iron wheels that you somehow fill with wet air.

Just two anecdotal nitrogen in tires stories:

The AI who takes care of our bird fill the tires with nitrogen. He said aircraft tires (& tubes as light aircraft tires are often not tubeless) are more porous than car tires and lose pressure slower with nitrogen. He still puts air in car tires though.

A certain local trucker who shall remain nameless is rumored to have run nitrogen and at higher than normal pressures from time to time to avoid having “the truck cops” visually detect that he was overweight.

That’s all I know about nitrogen in tires. I just run air in all our road vehicles. I do run water in some of the tractor tires, but that is a CG thing...

I use air in my tires on the Ferrari

is that high enough performance?

really, nitrogen filled tires is just as bogus a claim as man-made global warming

Bottled nitrogen doesn't entrain moisture like air coming out of a shop compressor. It's the moisture that's the issue more than whether or not it's N2 or just air. The moisture can lead to corrosion of the TPMS sensors given enough time.

And it sounds great!

So what was the price with and without the nitrogen??

I have often wondered how they managed to get all the air out of the tires before they filled them with Nitrogen... oh wait they didn't. So that tire is really not filled with 100% Nitrogen.

I call BS on paying more to put Nitrogen in your daily driver.

Locally, Tire Discounters made a BIG deal about nitrogen filled tires a couple of years back.

Not sure why, but I do not recall hearing those claims for some time.

I think maybe people caught on.

Local shop used to charge ~10 bucks extra when buying a new set of tires for it. Now it's included for free.

They fill and bleed of each tire three times to minimize the remaining moisture and Oxygen.

Well I thought nitrogen charge was more of a deal so I checked FM 9-207 Operations And Maintenance Of Ordnance Material In Cold Weather and the only time it is mentioned is for charging sights and equilibrators. Just making sure they are charged with dry nitrogen to prevent accumulation of water. No pressure discrepancies noted.

We serviced aircraft, according to Tech Order, with "clean dry air, or nitrogen".

Nitrogen results in less pressure differences due to heat delta from static ambient air, and the heat generated from taxi, takeoff, landing and braking.

So, if a tire is serviced to approx 200-300lbs (majority pressure range of aircraft that it truly matters, like fighters, bombers, cargo and civilian passenger aircraft), at an airfield at below 0*F say, Thule or Gander, and then flown, lands, hard braking and long taxi in Phoenix or Dallas with 100* + temps, you want a stable and still withing service tolerance in your tires.


The SR-71 and the Shuttle, nitrogen only. (even greater extremes)

Normal cars typically only benefit from the near 2x rate of loss of pressure from the 21% delta of O2 in "air" vs the nitrogen.

So a tire that may lose 1 lbs of air in a week services with "nitrogen", will lose 2 lbs of air in that same time serviced with "air".

That effects service of tire, and affects mileage. So for lazy folks with leaky tires, it might be a little benefit.

Most tires lose pressure over a very long time, so in "the real world", it matters very little.

This subject comes up regularly on the motorcycle forums.

It boils down to this:

If you think it doesn't matter, don't use nitrogen and you will never know the difference.

If you have OCD, use the nitrogen. It still won't matter but you will feel better.

If you race motorcycles, or Yugos, professionally go ahead and use nitrogen, it may make a small difference.

Disclaimer: This is my opinion only. A copy of this post and about ten bucks will get you a latte at Starbucks.

Nitrogen is only used because it's dry and will not corrode your rims or condense the moisture from air into an ice ball in the bottom to unbalance the tire in the winter.

I fill mine with a 78% Nitrogen mix.......

Well I could care less about your tires. As long as my fire control components are fog free and put warheads on for-heads on a US Artillery mil...(and OMG no new guys know what a mil is)...
