Got a email from VW about putting Nitrogen in my tires?

is due to gas being "dry",as it's processed and filter from the atmosphere. During this process water vapor is drawn out and the carcass of the tire lasts longer due to water not dry rotting the tire. Now for me no tire on this car has ever lasted long enough for this ever to become a consideration. It's a revenue stream. I fill my own tires with good 'ole "air". I could sell many things to my customers in the name of revenue, I decline to abdicate from my moral position. I guess that's why I don't own a boat, mansion, and a Ferrari like every one else.

than O, it's also slightly larger. So you get slightly less overall weight and less pressure will leach out over time. Reactivities to heat and pressure are also different between the two but, I don't know what effect that has on tires (if any).

was all about. I would never spend money to put air in my tire's unless it greatly increses my MPG. I just had never heard of nitrogen in tires before so i wondered if anyone had info on it. Also i wondered it the dealers claims were legit.

but I agree - air is free, so use it as you please. You can always let it back into the atmosphere when you finish with it!

It is popular here in Fairbanks, where we have a very wide temperature range, +95 in the summer, -60 in the winter. Tires lose a lot of pressure when it gets real cold. I am getting nitrogen put in mine this week.

From MY understanding, nitrogen fill is good for two things. You are correct in that "pure" nitrogen is dry, and it is the water vapor, not the O2 that caused greater fluctuation in the pressures from temperature. Secondly, supposedly the N2 migrates through the tire carcass more slowly than O2, thus requiring less frequent top-off.
I wager most of us here probably check our pressures once per month MINIMUM, and probably at least inspect more often than that, especially during drastically changing temperatures. In this case, just keeping your tires properly inflated and inspected should accomplish the same thing.
