#12782 of 13339 Reply to atomic sizes. by imidazol97 Jul 24, 2009 (8:55 am)
>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)

Replying to: 2010sel (Jul 24, 2009 3:30 pm) The size of your picture was making the rest of the messages on the page unreadable so it had to be removed. If you post it to your CarSpace page and then use the automatically generated code from there to display it, it will render correctly.

Replying to: mickeyrom (Jul 23, 2009 10:24 am) The subject of the discussion is all midsize mainstream sedans. The fact that we have to limit the categories to a certain number does not mean that the others which fit the category, such as the Optima, cannot be discussed. So please feel free.

Replying to: mickeyrom (Jul 25, 2009 11:00 am) It seems to be just about as midsize as a car gets, mickeyrom.

Replying to: mickeyrom (Jul 25, 2009 11:00 am) Mickeyrom, were you told that by a host or by just any old poster. My Sonata is an '05 and it that year the Optima & Sonata were more like twins than cousins.
