I know that when I do the paperwork on my incoming (hopefully 10 days or so) that the dealer is going to try and sell me having them fill the tires with Nitrogen. It's not cheap either. Is there any real benefit other than making my bank account even lighter? One of my concerns is, if a tire needs further inflation for some reason and I'm out of the big city what would I do? Can I combine Nitrogen and normal air?

The car is not going to be tracked or even Auto-X'd.

Is Nitrogen Worth It?
The air we breathe is made up of 78 percent nitrogen, 21 percent oxygen and a few other elements. To get the desired benefits for tires, nitrogen needs to be at least 93 percent pure, according to nitrogen service equipment providers quoted on Tirerack.com. So we're basically talking about adding an extra 15 percent of nitrogen and getting rid of as much oxygen as possible.

Based on cost, convenience and actual performance benefit, we don't think nitrogen is worth it. A much better use of your money would be to buy a good tire-pressure gauge and check your tires frequently. This is a good idea even if you have a tire-pressure monitoring system in your vehicle. The warning lights aren't required to come on until you have less than 25 percent of the recommended tire pressure. Having the correct tire pressure will get you many of the benefits of using nitrogen and will ensure that your tires last longer.

No, pass on it.

 

amazing how many people fall for it.....last time I checked they charged $20/tire to fill with nitrogen...lol....I can get a medium sized tank of nitrogen for $27 which would fill approx. 100 tires!!

+1 could not have said it better myself!

 

If the benefits were that great. . . Cars of this performance caliber would come from the factory with nitrogen. I like Hot Honda's post. . . Buy yourself a good TP Gauge instead and check your pressures regularly.

 

Not to disagree with the previous responses but when I had my 997 in Colorado I initially did not have nitrogen in my tires. I worked at around 6000 feet but my house was around 9000 feet. With the change in altitude and temp my tires were constantly needing adjusted. When I put in Nitrogen it made a huge difference, my tire pressures were much more constant and I almost never needed to adjust them. My example is not the norm but may be relevant to some.

 

I have mine filled with nitrogen (they make the car go faster ).... my dealer provided it free and its part of their customer service. It was a nice touch.

 

I use propane.

 

nitrogen is used in aircraft tires because nitrogen volume variation is very minimal going from extreme cold and extreme heat.

planes goes from -50F to +150F, many times a day
cars are not getting those extremes over such a short period. so variation is very little.

as other mentioned, check them regularly. especialy when summer will be there... :-) one day.. hopefully.... (stuck in canada...)

 

It's probably a gimmick. It's probably bogus. But then again in a member of costco and they will bleed and refill with nitrogen for free. I'm going to give it a try. Let you know what happens.

 

LOL.....Helium would give more performance.....at least an extra 5HP!!

 

As Nitrogen is inert gas so they are quite stable (PSI is almost the same when tires are cold or hot)

While when we fill our tires with air, tires pressure will be a few PSI higher when hot (which is operating temperature)

Therefore, if ones decide to use Nitrogen in their tires. It is important to fill 4-5 PSI higher (than the cold pressure) when using conventional air. Otherwise, it is consider tires pressure is too low.

I do not buy the idea of filling Nitrogen in diary drive cars. Can not see any significant benefit.

However, in race cars with Nitrogen filled tires, we can get the right tire pressure from the start. Do not have to waste time to warm tires up for 1-2 laps. In many cases, if the race start with cold tires, then Nitrogen filled cars would have great advantage over the conventional filled tires.

 

Thought this was a funny coincidence. . . . I just recieved my new issue of Car and Driver in the mail today. Looking through it I came upon an article on page 110 called, "Are You A Stroker." It lists the acronyms and phrases car salesman speak amongst their piers about different types of customers. Phrase # 19. . . "WHACK 'EM" is fitting to this thread. Check out the photos of the magazine to read what the term "WHACK 'EM" means to a car salesman.



F&I is the abbreviation for Finance and Insurance Dept (They guys that try to sell you all the extras).

 

No, it is not worth the money. Air is 78.09% Nitrogen. For all ut the most advanced racing teams this means nothing except extra cost. If the air is properly dried, there is only a trace amount of water vapor in it. This is what you reeally care about. The water vapor condensing and vaporizing over time.

If you are an F1 team or full on pro racer, sure there are very subtle differences especially when you are looking at controlling tire pressure changes to 0.5 PSI. For the rest of us, even if we track out cars, we will not see the difference.
