think of all those tires out there with 32-50 p.s.i. in them, shouldnt we have a day where we let all that old air out, so it can recharge itself with fresh oxygen molecules?

no, not for the sake of the tires! it because some of theses tires haven't been changed since 1962, that air needs to be recharged! put back into the system! out with the old, in with the new!

I don't know, but here is my thinking...
Tires are designed to contain just the proportion and combination of chemical compounds that are required for the tire to work.
Areas of low-density of a substance tend to become populated, over time, with higher and higher proportions of that substance when there is a high-density source of the substance adjacent to the low-density region.
As the substance leaches out of the high-density region (the tire material) into the low-density region (the air inside of the tire), it tends to reach a saturation point, or at least a higher vapor-pressure (which I believe will tend to slow the rate at which the substance continues to leach out of the high-density region into the low-density region.)
The slowing of the loss of vital compounds is a good thing, as it prolongs the period of time over which a functional mixture of compounds will be present in the tire material.
If you keep 'refreshing' the air inside your tire, you are keeping the 'vapor-pressure' low in the captured air inside of the tire...which causes the rate of vital substance loss in the tire material to be at its maximum possible rate...which can be expected to shorten the functional life of the tire relative to keeping the 'stale' air in place.
Besides, if you aren't going to eat the air, what do you care if it gets stale?
haha

Exactly. Nitro-Nize your tires!
Fill Your Tires With Nitrogen Today and Make Your Vehicle Up To 5% More Fuel Efficient
Nitrogen is a safe, more stable alternative to filling your tires with air because it leaks out naturally much more slowly and does not react to changes in outside temperature. That means your tires will remain properly inflated much longer, reducing wear and improving fuel mileage! It is a completely safe, dry and inert gas that is already in the air you breathe.
All tires leak air out slowly through a tire's rubber walls. That's why you need to check pressures regularly, and why you often find your tires are surprisingly under-inflated. Improperly inflated tires wear out much more quickly, decrease your fuel mileage and can sometimes result in complete tire failure. Since Nitrogen molecules are larger than air molecules, they leak out 3 times more slowly than air. So with nitrogen in your tires, they will remain correctly inflated for a much longer period of time and be able to handle the load capacities they were designed for. This results in extended tire life, improved gas mileage and improved handling and safety.

beleive me, my family owns an auto salvage yard in wisconsin. all you need to do is periodically check you tire pressure and rotate your tires. if your tires seem to be getting low in air after a few days of pumping them up then you should take them into a shop. you may have a nail or something in the treads. that is fixable. but if you have damage in the walls of your tire you are going to have to get yourself a new tire. and if one goes bad than you might as well just go and get a whole new set just so that you can get back to smooth riding.

air in tires don't become stale. the only thing you gotta do is check the level of air as over time air tends to want to escape. i see alot of people driving on the roads with low air in their tires, this is bad news because you get bad gas mileage and you may cause yourself an accident.
always check the level of air in your tires

No, that's not needed. The force of the air's pressure is all that matters, the air doesn't go bad.

You should change out the stale air in your head.

why, its not like the tires are breathing the air.?
