I have seen it help, what are you basing your facts on? do you work in this field and know what is really going on?



D and I both worked in the HVAC field, and although I'm not to the point of engineering, I think he and I both have a pretty good idea of the thermodynamics of gases.

The idea that a drop or two of moisture in a tire can make some magic measurable degree (no pun) of difference in temperature is ridiculous. I WILL agree that dry air might help prevent rust/ corrosion of rims, but that's about it.

The difference in molecule size between O2 and N2 that would make the arguement of "preventing leakage" is again off the mark.

The other obvious question we all have to ask nowadays is "is this green?"

So let's add up the tremendous amount of energy it takes to extract Nitrogen from wherever you are going to get it, IE liquify air, all the energy it must take to filter purify, etc, and the transportation of VERY heavy bottles and storage containers as opposed to....

just running a compressor and possibly an air dryer/ filter
