Just about every race car runs nitrgen because it has a lower moisture content. When the tires get hot the moisture expands causing the tire pressure to increase. This does 1 of 2 thing depending on the tires. If you have bias ply tires they expand and get bigger (unless you got one of those set they screwed up durring manufactuer and the contract (I can't explain that one)). If you have radial tires the pressure builds but the tire stays the same size and the spring rate of the tire increases. Now this is for race cars Mainly circle track cars. You will NEVER get your tires hot enough on the street for this to matter. Save your money. The HHR is a great car, it's fun to drive, it's only 175 hp, it's not a race car. lol

I agree. While Nit. Is used in the avaition Industry, It Is most generaly not used on light a/c. Mostly air from an air hose to inflate to 30-40 PSI. These are mostly single engine aircraft. Land and take off between 60-85 MPH. Aircraft that land and take off at a higher speed 120 Knots-160Knots,and a larger gross weight will use Nit. The reason is that the expansion at altitude (30-60K Feet) is a lot less then if they had air in them. As far as landing, a wheel tire pressure on a DC9 or MD80 will have a cold tire pressure of around 180 -230 PSI. Tire pressure will expand to over 360 PSI after landing. (Wheel spin-up, 0 MPH to 180 MPH+ in just a few feet). A 777 tire pressure will expand to even higher numbers. While that is a lot of pressure change, It still is less then if just "air " was used from a hose.Then you take into account the temperature change and condensation inside the tire, well, a lot less water present. Some of those aircraft tires will be "Recaped" up to 14 times before the carcus is found unairworthy. Generally with car tires, they are history after 80K miles. So I say,"DON'T WAIST YOUR MONEY". Just keep the tire pressure at the recommended pressure and you will get better gas millage and longer tire life.

Nitrogen
Well, as a former military person and former aviation mechanic, we now run Nitrogen on the vehicles. I started in July, and have done my monthly tire psi checks, and my results here in PHX are very good. I noticed on average a small 0.5 psi drop on all 4 tires on each vehicle after a month. Wow, that is a big difference from 2-3 psi on compressed air. And as for someones atatement about sucking the air out, Purigen 98 system does this. The guy I found, came out to the house, and deflated all 4 tires per vehicle, the filled completelt, then sucked the tire, then filled, then sucked, then topped off at the correct PSI. So, if any water moisture was left, it should be minimal. It is one of those things, that once it is done, it just makes others things easier.
Just my $.02 worth.

Michelin and Audi are working on it and have vehicles on the road. It's quite an interesting concept. The metal rim is the size of the retention lugs and hub the "tire" is multi spoked from there to the surface tread. I'll post if I find the pictures.
here's one article...."gooogle" ...airless tires...for others.

We got this on email today concerning this issue.
RMA issues service bulletin on nitrogen inflation
Tire Business staff report©
WASHINGTON (Nov. 6, 2006) — The Rubber Manufacturers Association (RMA) has issued a service bulletin, “Using Nitrogen to Inflate Passenger and Light Truck Tires in Normal Service Applications.”
The bulletin was issued because the use of nitrogen systems among tire retailers has increased recently, the RMA said. The inert gas has often been used in specialized tire applications such as aircraft, mining, racing and commercial use, the RMA noted, because it reduces the risk of internal combustion and variations in inflation pressures.
But nitrogen generally is not required for normal tire use, and depending on nitrogen alone to reduce inflation maintenance may lead to dangerous underinflation, the association warned. Other sources of pressure leaks, such as punctures, can negate the benefits of nitrogen, the association added.
“Whether inflated by air or nitrogen, regular inflation pressure maintenance remains critical and necessary,” the RMA wrote. “Use of nitrogen alone is not a replacement for regular inflation pressure maintenance.”
The bulletin is available at www.rma.org.
