I don't know the practical aspects of N2 v O2 in modern tubes, but the
partial pressure of O2 in a tire inflated to 30 psi is 3x that on the
outside of the tube. If anything in the rubber tended to oxidize, it
would
oxidize significantly faster at the higher O2 partial pressure.
It may not be a practical problem in tubes, but I'll bet it makes a
difference in a strut (1000 psi?)

Is anybody suggesting the use of O2?

How do you not use O2 if you use air?


Well if we are going to call using "air" using O2 we might as well call it
using N2. There is a lot more N than O.

Nobody but you used the phrase "use O2", notice the phrase "partial pressure"
in the original post.
