Nitrogen or Air?

Either
A)you were driving around with 3 psi in all 4 of your tires before you switched to nitrogen

b)you drastically changed your driving habits, from "having the gas pedal floored at all times" to "grandma driving"

c)you moved from an area of perfectly flat roads to the mountains

d)you are exaggerating

All I can tell you is what I did and what gains I experienced. I drive the same way all of the time. The 4 MPG gain was on a road trip. Since I've owned the car I have not gotten 29MPG on this car. The only change was the nitrogen. The only thing I can guess is that nitrogen weighs less than air. That has been my experience. Hard to impossible to believe, I guess. Just what I experienced. I've also not seen a UFO or have been obducted by space men. Some say they have experienced this.

I gained 32 mpg with my tornado and an electric supercharger.

3. I and my wife have noticed a smoother ride since switching to nitrogen. Uhhh, never heard that one......
4. Nitrogen contains no moisture so the inside of the tire won't rot like they do with air. VERY few will be on the car long enough to rot........

I paid $49.00 for four tires at the dealer and when ever I need a top of at oil change time he does it for free. And by the way nitrogen is lighter than air and my gas milage went up by 4 MPG. No way....Ask a reputable tire shop for their opinion. These are my reasons.

In red....

maybe try laughing gas!

I use Nitrogen in my kids 1/4 midgets do to the minimum pressure changes. Never really thought of putting in my car. I have a tank in my trailer at all times only cost about $12.00 to fill tank and could probably fill all my tires 10 times with it.

Alls I know is that my tires vary 5-6 pounds a day. If they were closer to the right pressure it might help on mileage. Obama said so.

I know that nitrogen does not react to temperature variances like regular air does. I have considered switching out myself.

Dealer put methane in my tires.. they hooked up to a couple of nasty hicks after a trip to the unlimited bean burrito buffet.

Are you serious? You think the dealers put it in because it performs better and not because they make $25-$50 to fill 4 tires? Get real, do you actually think the paint protectant, interior stain blocker, and pinstripes a lot of dealers try to force on you are worth the $750-$1500 they cahrge you? It is nothing more than BS gimmic marketing ploy to fool the naive customer into paying for something that is worhtless for everday driving. If you race at speeds up to 150-230mph then get nitrogen, if not don't waste your money. Don't take offence please, its just the way it is.

i really doubt the 4 mpg gain.

Sorry but this is all and is all uninformed propaganda. As posted up above, compressed air contains between 75-80% nitrogen.

There have been multiple tests and studies proving that there is NO gains over regular compressed air under NORMAL driving conditions.

- Nitrogen will still expand between 4-6 psi under normal driving conditions. Only under extreme circumstances (such as the extreme cold tires in jets experience and the extreme heat race cars put their tires though) is there any noticeable difference in the psi levels between compressed air and 100% nitrogen.

- Pressure loss from a puncture in the tire is nearly identical to that as it is with compressed air. Using 100% nitrogen will not reduce the rate at which you get a flat.

- Introducing the placebo effect. You was told that you will experience a smoother ride so therefore you think you experience a smoother ride. Unfortunately in the real world there is no ride difference between nitrogen and compressed air. Actually if anything it should be the opposite. As you said yourself, nitrogen is larger in size as such there is less room for the nitrogen to move around. This creates less give in the tires making the ride stiffer and harsher, not smoother.

- The inside of a tire will NEVER rot under normal circumstances. The outside of the tire will always rot before the inside. If you have a tire failure because the inside rotted, then you have larger issues.

- Yes nitrogen is lighter then air HOWEVER the same does not hold true when in a tire. The weight of the tire only varies by a couple ounces. Do you really think a couple quarters per tire will make that much of a difference on MPG? No it doesn't. The tests that showed a MPG difference in a controlled environment showed a 1-2% increase. On a 20MPG car that's a difference between .2-.4 MPG. Well within the margin of error of the computer.

I have nitrogen in the tires only because the dealer put it in at delivery for me. I've been told great things about it and it sounds cool to me to brag about it, but I'm not sure I notice anything so majorly different in the ride vs. every other car I've had with air. I will say that the pressures do stay pretty stable over time, but is it really of any functional benefit?

Impressive.





But let's get serious. Those blue valve stem caps are just UGLY!!!!!! lmao
