After reading two "nitrogen in tires" threads, that is the conclusion I've come to. The only benefit of nitrogen in passenger tires is increased profits in vendors pockets.

1) A mass produced tire & wheel combo built so precisely , that the size of one gas molecule vs another is the leading cause of pressure loss?
Hilarious.

2) When that day comes you can throw those lead balancing weights right out the window. Or airlock as the case may be since we'll be taking week long vacations on the moon by this time

3) Nitrogen obeys the gas laws. Nuff said.

 

Yeah, I was wondering about that one with all the "it expands less when it's hot" talk -- doesn't make any sense to me. Also the "it's a bigger molecule" argument seems completely silly given that 1) It is in fact not a bigger molecule, and 2) air is mostly nitrogen anyway!

The most compelling reason I've heard to use it is that it reduces oxidation on the rubber inside the tire, but I have never heard of a single case where that was the cause for tire failure (as opposed to, say, tread wear or punctures).

I agree.... the main observable effect appears to be loss of brain cells (or is there just a correlation between those who pay for N2 and those who had too few to begin with?)

Every car forum I have ever been on discusses this topic. This, the vortex, and the benefits of adding acetone (will it increase my mileage!!!1!!!one!!!!)

Using dry air will net the same effects as nitrogen. None of us are autocrossing our Jeeps, so tire heat/expansion/whatever are much more negligible. The only reason the water affects the pressure/volume curve is that it goes through phase changes, whereas the other gases won't change phases without taking a trip into outer space.

So, in effect, don't buy it. If it comes with it, fine, but fill it with normal air. If you are really worried about your rims rusting, use dry air. It isn't common though.

 

now hold on, we can sell nitrogen for your tires . it can add life to your tires, increase gas miles, keep your wheels from rusting out, add horsepower , you never need to check your tires as often . now step right up and get yours filled with our new and improved nitrogen less fat and more filling

 

I just filled my tires with mayonnaise.

 

Good idea!! I will use veganaise!!
