Nitrogen in Tires?

Compressed air is 70% nitrogen already. Save your money.

Waste of money IMHO. If you are changing the outside air temperature of the climate you are driving in or operational heat buildup VERY quickly and/or dramatically and need that consistency in pressure, then go with the nitrogen, or better yet, argon. They are inert gases. For automotive applications, it's a total sales gimmick IMHO. Aircraft tires are inflated with inert gases because of the accuracy needed for a set tire pressure specification ( some I know are 140psi +/- 5psi) that can't be maintained with common atmospheric gas over the operational ranges, which can vary widely, set by the aircraft builder. Checking and maintaining your car's tire pressure once a month using just plain old air is the best method of avoiding premature wear and unsafe tire conditions IMHO.

As well as the large chunk of ice that can develop in the tire if high-flying aircraft if the inflation air had lots of moisture in it.

That said, most smaller aircraft, including mine, have plain 'ol air in the tires. Even my tiny tires accelerate from 0-80 or 90 MPH in an instant!

Nitrogen in car tires is a ripoff.

True!! And you should also replace the air in your tires every spring and fall. The air wears out after a while...

If you have to ask if it's a good idea to do something, it usually isn't.

Why use nitrogen when someone is giving away free hot air like the crap they are feeding you?

True, but it's only a very small improvement - measurable and quantifiable, but just barely. Don't pay extra for the privilege, either through higher overall prices at the shop or as a separate line-item. If they want to use a nitrogen generator because they think it's better, they're welcome to.

All they're doing is running the air through a molecular sieve filter that catches and purges the oxygen and CO2 from the compressed air, then wringing the last of the moisture out.

Apparently, the small amount of water in air makes the pressure vary more than gas without water in it (the oxygen, CO2, and other gases have little to do with it). At 30 psi, the concentration of oxygen, nitrogen and water are about 3 times what they are in air.

For God's sake, the tires are NOTHING compared to a passenger cabin containing dihydrogen monoxide. GET THAT S*IT OUT OF THERE QUICK. If you have kids, you do NOT want to take a chance. Make SURE you eliminate all dihydrogen monoxide from the passenger compartment IMMEDIATELY.

THAT explains it!!!

Here's a page describing the dangers of dihydrogen monoxide. Dangerous stuff:

The only thing I can say about it for sure is, AVOID BREATHING IT AT ALL COSTS!!! Breathing anything more than just a very small amount can cause immediate death!

One can use Spring water to keep the cooling system from freezing in winter, as well ;)

Tom & Ray say forget it.

Actually, they say that the tire pressure is more consistant with the nitrogen than air, because there is no water in nitrogen. But, unless you race cars, it doesn't make enough of a difference to really matter.

Jeff

Around 80%, of the stuff in all of my cars tires, is nitrogen. I wish helium was at that percentage, I might use less fuel LOL

mike

dont drink water...

That's why I only drink Scotch, no DHMO in it either. Jack

Well, there is some DHMO in Scotch Whisky as a byproduct of the manufacturing methods, but at well below critical quantities. The alcohol content will get to you long before the DHMO will.

Now you /do/ want to be extremely careful about dilution of the base Scotch with any more added DHMO than absolutely necessary...

;-P
