If you want to keep the approximate 95% nitrogen that you presently have in your tires, then you will need to keep filling them with nitrogen. If you want to have your tires to eventually go down to 79% nitrogen, then you can start filling with air. It won't go down to 79% all at once, because the air that you are putting in the tire is 79% N2. So your 95% nitrogen filled tires will go down just a small percentage each time you use compressed air.

Sort of like calculating radiation half lives...

And no money spent/wasted!

Some people want the best of everything. That is why I am one of those that will pay extra for nitrogen. Nitrogen filling stations fill, then drain then refill your tires 3-4 times to increase the purity. Plus, it also removes the the moisture that can later condense and cause uneven wear because of imbalance, not to mention corrosion of the steel belts that may end up exposed. Also, by removing the oxygen, the rubber lasts longer because there in little to no oxygen to cause crosslinking of the rubber which causes hardening and cracking. Also, you need to add air less often because nitrogen molecules are larger and permeate the inner liner less often which is worth the extra $$$$ to me. If you can't afford the extra cost, then keep putting air in your tires.

I know of country boys filling their tires with natural gas(only cause they had a well at their disposal). Has anyone tried helium? Perhaps one would get better mileage as it's lighter than air.

I back up the 99.5% uselessness of the product with 100% conviction! (for the average everyday person).

The inside valve stem is for the inner liner, its a tire in a tire that we use on tracks over a Mile, as far as getting all the air out its tough, to purge we just let the air out blow them up with Nitrogen then let that out and fill it one more time, Never can get all the air out
