Nitrogen

Should I use Nitrogen in My 2014 RT tires ?.
Thanks.

I've heard both sides of that argument, and, in reality, you are doing that already, as most of our air is nitrogen anyhow. Now I know there are proponents that say it makes a difference, but, I finished chemistry right at 50 years ago, but I think it is something like 70-80% of our atmosphere so unless you compressor selectively removes it, you are, already, my numbers are liable to be off, but I'm not sure it is worth the extra $$$'s. jmo

Not much difference, but?

Nitrogen is slightly heavier than air, so you get extra weight:roflblack::roflblack::roflblack:. Seriously nitrogen doesn't have the temperature expansion or contraction as much as air does and the claim is it doesn't leak out as fast as air does. Supposedly the tires run cooler to, thats partly why the race car drivers use it. I don't know if its worth the extra money to use, when most do a periodic check of their tire pressures and add air as needed. My 2 cents. I wonder if it will stay in my rear shock longer. :joke:

Yes air is just over 80% nitrogen, but I expect the argument goes something like, yeah, 80% nitrogen, 18% corrosive oxygen and 2% God knows what, but certainly including water vapour! Would you put 80% petrol in your tank? Personally, I'm not convinced, but my local Kwik-Fit puts in Nitrogen and then I go and top up with good old-fashioned Scottish country air!

Nitrogen is a larger molecule than oxygen, and, as a result, does not migrate as readily through your tires. The oxygen molecules in your tires pass through the rubber tires, albeit, very slowly. With 100% nitrogen, the tire pressure stays more consistent. Also, with regard to expansion and contraction from heat, a lot of that is caused by the moisture in the compressed air . . . an air compressor does not dry the air when it compresses it. Nitrogen, for tires, does not come from a compressor. It is obtained from liquid nitrogen, and, as a result, is very dry. Nitrogen is also inert, as opposed to oxygen, so is better for your tires . . . here is a good link: http://www.mobiloil.com/USA-English/MotorOil/Car_Care/Notes_From_The_Road/Nitrogen_for_Tires.aspx

I have it in my tires, I do not think it makes a difference, imo :thumbup:

Only if you change it every 5,000 miles.

why?

for the same reason you buy it in the first place...to keep the supplier employed.

I use it in my truck and wife's car, and I do like it.

Nitrogen versus compressed air

Putting all the scientific chemistry mambo jambo stuff aside. The primary reason racers use nitrogen is PORTABILITY. One tank should last them a whole weekend so they don't have to pack extra extension cords for a generator and a compressor. All they have to do is chain the cylinder to a tool box or a safe pole, attach their regulator. Then their distribution manifold ans set the pressure they want for the air operated tool

Air is 78.09 % nitrogen to begin with. Oxygen makes up 20.95 that's totals 99.04, the rest is a little argon and some other gas of some sort.
The reason tires run a little more constant pressure with Nitrogen is that there is little or no moisture in nitrogen if the supply system is purged correctly. The moisture is where the majority of pressure fluctuation comes from, moisture is a non condensible so the pressure increases when it gets hot. With all this being said, I wouldn't pay for it. My car had it from the beginning and I have always simply topped off with Air if needed. I've never seen any difference in the tire performace, ride or anything else. We have almost 80% nitrogen for free anyway.

:firstplace: You got that right I always used it in my corvettes and never had to add air. :thumbup:

 

[Chupaca]

Gonna side with...!!

those who say not worth it. Until they offer it at the filling station it's more trouble than it's worth. Our tires are much smaller and we don't heat them up like racers do. We will not be looking for tire shops that have it when we need to add a lb or two of air. Jmo...:thumbup:hyea:

It's 'free' at Costco if you're a member.

Just say'n.

But you won't need to that is the big benefit it holds steady or at least it did for me all year round. No more adding and checking.

I have done research on this subject and while there are certain advantages there is no empirical evidence to prove it is worth the money. With or with out nitrogen you still need to check your tire pressure regularly and if you have every watched them put a tire on you will see they use a lot of soap and water so even after the nitrogen purge moisture is still in there. I would be the first guy to use it if there were tangible results from doing so.

All I can say is on my Vette there was a 3 lb difference cold to hot tire with N and 6lb with air. It was over a year before I had to add any air to the tires too held same air pressure in hot or cold weather. Using N may help with ballooning too. In a pinch a little squirt of air is not going to make the N go bad either.:dontknow:

Some people run 15% petrol in their tanks. E85

...and other people run .07 alcohol in their bodies...doesn't make it an optimum use of alcohol whether it is in the gas or inside the body...
