Nitrogen vs. Oxygen

-
O2 "permeates" approximately 3-4 times faster than does N2 through a typical rubber, as is used in tires, primarily
because O2 has a slightly smaller effective molecular size than does N2.

I found this and thought I'd share.
 
some folks here are confused, tires are never filled with oxygen-most often filled with AIR-78% nitrogen and 21% oxygen
 
Another one of those conversations where we discuss the finer points and opinions of something that makes a squat of difference on your 40 year old car. :D

I'd use nitrogen on a car that I was racing at 200 miles an hour, but only because it doesn't expand when hot like oxygen and change the tire pressures.
 
I got new winter tires for my 300 about 5 years ago. Of course I was not asked if I wanted the Nitrogen, they automatically just put it in. I do have to say that the 3 years I ran them, then gave them to my brother (I sold the car) and he ran them for at least 3 more years. Neither one of us ever had to fill the tire with air. They stayed a constant 35psi. Just my experience with it.

Now with that being said I had to purchase tires for my Durango (thanks to some punk *** that slashed 2 of them). I was curious if Nitrogen was still used. I spoke to the counter guy about it and then at a different time the tech that was installing my tires. They both agreed that it was a gimmick and not worth the money! They didnt even have it at the shop, so they didnt have to try to talk people out of it.

Tire rot? I don't usually talk like this, but are you ******* serious?

That's THE absolute stupidest thing I ever heard. "My" plan with tires on a hot rod include wearing them out WAY faster than they ROT.

dumbasses unite.......and then GO AWAY.
