Eric:  I have a friend here in Cedar Falls Iowa that fills his tires exclusively with nitrogen.  He runs a really small tire mounting and balancing shop out of his garage and does mobile repairs as well.  He says that in order to mount tires and fill them with nitrogen, you have to make sure the bead sealing surface is absolutely pristine, so there's no chance of micro leaks from pitted sealing surfaces.  I think he charged like $10/tire to do the fill.  Not sure how he would evacuate the normal atmospheric air form the process, but I have used his services on my Vanco II Continentals mounted on Mercedes CLK forged aluminum rims(mounted on my 90 GL  BTW)  and they haven't lost  1 psi in like 4 years.  I think Tire Rack offers the service as well.  NASCAR Racers use nitrogen     YMMV

Hi folks,

this time of year I have a hard time keeping my tire pressure content.  the temperatures outside vary greatly.

        I recently learned that a friend has a car with Nitrogen filled tires.  Is anyone doing this with your vanagon?  Do you have any benefits to report?  Will this help with content tire pressure and tire wear?

A little reading on google gave me different opinions on the value but it sounded like my needs would have the most benefit from a nitrogen fill.  that is a car  that is used infrequently, has low mileage on the tires, and thus would like the tires to last longer. 

I’m not sure how expensive it is to fill this way and would like to hear if anyone has experience.
