Nope diffusion IS the scientific explanation...it's been understood for ages.
Yep, will take longer for it to leak in, as I showed with the driving force (pressures).
Interesting if you want to minimise oxygen migration rate THROUGH the rubber, you need to have 3psi inside the tyre to start with...that's 3 out of the 45psi absolute, or 6.7% oxygen in the tyre at initial fill.
