Still not sure about putting Nitrogen in your tires?

I'm an A/C contractor, we purchase dry nitrogen to pressure test and leak check air conditioners but we don't use it in our truck tires. At 10 dollars per tire, I can see it would be quite profitable but then, I don't have an issue with a business trying to make a profit. I for one, know that the government takes 40% of every dollar those people make. If someone pays them $10 for nitrogen, so be it. I've seen people pay $2.50 for a 16 oz. water and no one complains.

Same here. I'm a shop owner. Nitrogen doesn't leak out as fast and pressures remain more consistent. We charge 5 bucks a wheel. If you don't want it, don't buy it. It's your $200 tire. If it runs low on air, we can get you another one. I run it in all my vehicles.

That's one funny video! He kinda states it the way it is. I topped off the tires on my wife's car with good ole air, but I still put the green caps on. I hope the nitrogen police don't catch me!

I too say it's not a scam, in the sense that everyone who's touting it is trying to intentionally steal your money. My car came with N2 and green valve caps. No big deal, I just put air in them myself when they're low.

IMHO the benefits of N2 are small for car owners and maybe smaller for RV owners.

$10(A) a corner !!! Darn profitable scam !

A few years ago a "nitrogen salesman" approached me in the RV park where I reside for the summer. He tried to hand me a pamphlet saying, "Sir, would you like to talk about the benefits of using pure nitrogen in your RV tires?" I responded, "I have a masters degree in chemical engineering." (I lied, I don't!) The salesman said, "Oh!" He took his pamphlet and moved on never to be seen again.

Yes a nitrogen bottle comes at much higher pressure than the shop compressor.
But if you have ever emptied a 250 psi shop compressor you know a lot of water comes out and makes the air quite dry.
Just fine for RV use. But you will not get a sticker and a check ($$$) from the nitrogen supplier and sponsor.

The ideal gas law (PV=nRT) applies to DRY air equally as it does to DRY N2. As the others have identified, it's all about the moisture content and in a MOHO, it's insignificant.

"It allows the tire pressure (50 pounds per square inch) to remain constant throughout the race regardless of the temperature, which can reach 200 degrees Fahrenheit."

I caught that too! I guess that's why the cars cost so much. :)

As azdryheat stated, it's the lack of moisture in the nitrogen that should get the credit. NOT the nitrogen.
