I love that "bleeds through the rubber" thing about O2. Here's why.
If I fill the tire with regular air and much of the O2 "bleeds out" what do I have left? N.
Put in a little bit more regular air, a little bit more O goes in with it.
It "bleeds out". Now I have even more total N.
After about what? Say four regular air fills I should be getting close to 100% N anyway, for free!!
Hehhehe. Or: Not enough O2 "bleeds" anywhere to actually make a considerable difference.
Can't really have it both ways.
Science!
Tell me how much O2 "bleeds out" over how much time and anyone can write the fractions math to tell you how many refills it'll take of regular air to get to 100% N in the tire, turned O2 sieve.
Next step is to calculate how much money you'll save by just waiting for the tire to do all the work for you!
Therefore, my usual advice: If you can do N fills for free, go for it. If not, don't bother.
