Replying to: imidazol97 (Jul 23, 2009 8:06 am) Since I have filled my tires with nitrogen,I have had no loss of pressure.That is a fact in my case. Replies to this message: imidazol97 (Jul 23, 2009 12:12 pm) backy (Jul 23, 2009 1:23 pm) mickeyrom (Jul 23, 2009 1:33 pm)

Replying to: mickeyrom (Jul 23, 2009 10:22 am) Yeah, but have your tires lost pressure? Replies to this message: mickeyrom (Jul 23, 2009 1:33 pm)

Replying to: backy (Jul 23, 2009 1:23 pm) Not so that I noticed.In my Chrysler I used to have to add air constantly,but not since I added the Nitrogen.For me it's been worth it.

>I wonder how this works? Here is a diagram of molecules found in "air". These are by NASA and are supposedly to scale. Note that the oxygen molecule is larger than the nitrogen molecule. In every picture. I would think the nitrogen, being a smaller molecule, would have an easier time escaping from a microscopic hole/leak in the tire/wheel assembly than would oxygen (or other more complex compounds found in regular air).   The oxygen and nitrogen shown are actually atoms; they exist in diatomic form for both. The relative sizes of the diatomic forms may be different than the monoatomic forms imply.   I believe that the quality of the materials of the tire, the seal at the bead, and the valve stem have more to do with the unit not seeping air out (which is 80% nitrogen, remember?) than does the extra 15% or so nitrogen. It makes nice advertising and is sort of like the 30-minute informercials.   I used to have X-Ones on my car and it lost practically no air. I read later that the X-One was used by Consumer Reports as the best quality tire for a long term test on how much air pressure loss occurs. They pumped up tires and then waited months to check the remaining pressures.   Since this topic is off topic for mid-sized cars, I was not going to respond or post again. There's another forum referenced in an earlier post about nitrogen in tires.

Your picture is too big. Could you reduce it? Replies to this message: 2010sel (Jul 24, 2009 3:30 pm) pat (Jul 25, 2009 8:38 am)

Replying to: elroy5 (Jul 24, 2009 1:08 pm) No, it is on the web. Not my picture. Just right click it and click "view image". Or you could just click on the link I supplied. Sorry about the size. I had no way of knowing this message board would not display it correctly. Replies to this message: pat (Jul 25, 2009 8:38 am)
