Damn, that must be so volatile at normal running temps

 

I put helium in mine, makes them lighter. Nitrogen is for suckers!

 

I've heard of it but after looking into it, it just did not seem that the pro's were enough to just-tee-fi it to me.
Never heard or read about a better ride however....

Plus after years of using "regular" air I just didn't/don't see a need.

But if it works for you, go for it.

 

well i asked about it awhile ago while at the shop. and they gave me the same speech. so when i got the new tires put on they told me that they went ahead and filled the tires with nitrogen (no charge) and honestly i dont see any down side. not sure if i can say i see a upside though. since they were brand new tires, i cant say that any difference i experienced was due to the nitrogen.

 

the only way your running all nitrogen if if they pull a vacuum on the tires before filling.... and i prmise you they didn't since thats impossible to do

 

Damn, you beat me to it

 

I don't care who you are - that's funny right there.

As far as "vacuuming" out the "air", I don't know how tightly they do it but part of the process is sucking the air out before filling it with Nitrogen. And I don't mean just letting the air out, it is sucked out.

The main thing that sold me on trying it was the sensitivity, or lack thereof, to temperature change as far as pressure goes. I don't know about other racing series, but I know that reason is exactly why NASCAR tires are inflated with Nitrogen - to control how much pressure builds up from the heat. So, there has to be some science to it. How much transfers to a car with street tires at highway speeds, I don't know.

I know that, in the winter time, the tire pressure monitoring system drives my wife nuts with low pressure alerts which means she, in turn, drives me nuts to fix it all the time. I had this done about 6 weeks ago so it hasn't been cold enough to see if this will be a cure for it. We shall see.

Maybe I just paid $39 for the tricked out little green valve stem caps they put on to indicate they are filled with nitrogen.

 

Well, short of protecting the TPMS sensor, I don't think normal daily driving would really demand for it.

Unless you roll in the GT-R round that 'Ring =p

 

Tire pressures are supposed to be checked when the tires are cold.

If the nitrogen dealer is going to adjust tire pressures, what are the logistics? Do you leave the car overnight? Do they give/sell you a good tire gauge so you can check pressures at home when they're cold, record the numbers, then let them add a difference after you drive over?

It's my belief that race teams started filling tires with nitrogen for the same reason they use nitrogen for the air guns on pit lane.

Nitrogen beneficial for racing. For a DD, waste of money. In the cold when tire deflates a lb or two, or dear god no! Add it back in at the gas station.

 

No, I wouldn't and I don't think they expect you to bring the car to them and leave it if your monitor says it's low. What I'm saying is that if you use a regular air hose to bring your tires up to pressure, the cost covers you taking the car back to them to have them refilled with Nitrogen to the proper pressure. I hear you that they should still be cold when doing so. But, the point is or is supposed to be that you shouldn't need it done to begin with because of the Nitrogen. However, if you get a flat and have to have it repaired and filled with regular air, the cost covers taking the repaired tire back to them to be refilled with Nitrogen.

Race teams use Nitrogen for impact wrenches because they more reliable and can make the guns spin faster. They use it in the tires to better control the amount of pressure buildup once the car hits the track and starts to buildup heat in the tires.

 

Tire pressure varies with ambient temperature, so you have to add or subtract air (or nitrogen) at least seasonally. Also add some periodically to replace what hisses out when you put a pressure gauge on the valve. I't not just if something goes wrong. I bought a small compressor because pumping tires myself in my garage is less trouble than keeping track and having to calculate the delta to add to warm tires after driving to a gas station.

I've always thought that race teams use nitrogen because it's available, doesn't cost a whole lot, and a bottle of gas is more reliable than a compressor. At home, though, I'd rather not have a high pressure gas bottle sitting around.

Air Pressure: When and How to Set

 

The cynics here are correct. Being a science junky of sorts, I researched the chemistry and physics involved in the claims. Basically, they won't get sued for what they're selling, but other than that, it's all a bunch of bullshit.

The only benefit was to drive up the stock price for industrial nitrogen supplier companies. They appreciate your business!

 

at least you get a phenomenal set of four lime green valve stem caps, holla fo' a baller ....

 

Rolled five N2 threads into one, so the airheads can find it easily, and stop making new ones....
