Help! Nitrogen or regular air for tires?
I have a 2007 c6 base corvette with aftermarket rims and tires. I brought the car used from the dealer and now it is saying that the tires are low on air and i am not sure which one to put regular air or nitrogen as i am unsure what they have in them right now. I have nitto invo tires with the z06 rims. Tire sizes are front 245/40zr18 and the back is 285/35zr19. If anyone has a solution please message or post here thanks!

I would go with air. Never could see the benefit in paying extra to fill tires with Nitrogen. Regular air is 78% Nitrogen as it is and works just fine. Why complicate things?

Mike - If you plan on racing her, go nitrogen for sure. As most articles state, nitrogen is certainly more stable over temperature. As I taught my younger son years ago who was racing, change your tire pressure by 1 psi and notice the difference in handling. Loose to neutral.. Push to neutral...
If you're gonna track the car on a road course or oval where you're gonna run it long enough to build up temperature AND where 1 psi can make a difference in handling, then go nitrogen. For all other applications, nitrogen is a waste. Go with good 'ole air that contains more than 70 nitrogen already...

The only real practical advantage I see for nitrogen is that it is dry (compressed air isn't always) which can help prevent corrosion and failure of TPSs. Other than that (and maybe even that) is fluff IMO.

I'm going to find out for sure, but at this point I would not make hasty decisions. I bought a Lexus 19 months ago that the dealer had put nitrogen in. In that time I've never had to add air and the pressure has always been within 1 psi difference at the most (and is usually identical to previous readings).
Last week I had a nail in a tire and had it repaired at Discount Tire. As you would expect, they did not put the nitrogen in it. They did check and confirmed that they had all of the tires at the same pressure. I'll be watching to see if that one tire does vary over time compared to the others with nitrogen in them.

The only advantage of nitrogen is that the nitrogen molecule is larger than an oxygen molecule and thus leaks out of the tire slower. But it still leaks out. The concept that nitrogen is less affected to pressure variations due to tire temperature is pure baloney. All gasses follow the ideal gas law.
From: http://en.wikipedia.org/wiki/Ideal_gas
An ideal gas is a theoretical gas composed of a set of randomly-moving, non-interacting point particles. The ideal gas concept is useful because it obeys the ideal gas law, a simplified equation of state, and is amenable to analysis under statistical mechanics.
At normal conditions such as standard temperature and pressure, most real gases behave qualitatively like an ideal gas. Many gases such as air, nitrogen, oxygen, hydrogen, noble gases, and some heavier gases like carbon dioxide can be treated like ideal gases within reasonable tolerances.[1

I made a mistake of putting nitrogen in my tires on my van. When I got a puncture, I got air put into one tire. I notice all 4 tires loose and gain pressure the same during winter and summer. Nitrogen is a joke.

Put nitrogen in your tires only if:
1. You have more money than you know what to do with;
2. You want to have a problem finding a local merchant who has it when your tire(s) get low;
3. You've used the search option and you missed all these threads:

In brief, check out this article...
http://tirenitrogen.typepad.com/tire...re-change.html
Here's the first two paragraph. It spells out the major points...
"There is no significant difference in expansion and contraction characteristics of nitrogen compared to air when moisture is absent. Expansion or contraction of either gas, in relation to temperature change, occurs to a similar extent over the commonly encountered pressure and temperature ranges releveant to the discussion of tire inflation. There is no practical difference as long as the gases are dry in a fixed volume container such as a tire.
On the other hand, water is usually present in the case of conventional compressed air where dewpoints can be as high as 70F, compared with -50F for nitrogen. At lower temperatures, water (as a liquid) occupies very little volume. However, as temperature increases liquid water vaporizes to become a gas and its volume expands. This causes total tire pressure to be higher than it would be in the case of a dry gas, such as nitrogen. Thus the presence of water in a tire contributes to wild pressure variations as temperatures change"
