Can you put regular air into tires that when bought were filled with nitrogen? ?

My tires are low and need a little air.. 2008 Chrysler 300, Continental tires.

yes it wont hurt anything othr than lowering your benifits of the nitro
Air is 78% Nitrogen... so of course you can.
Yes. It won't hurt anything.
Yes. Nitrogen is the biggest scam in tire sales/repair I've ever seen. Air is about 80% Nitrogen to begin with. The claim is that Nitrogen will hold pressure better because the molecules are larger. Let's just say for sake of argument that was true, and the other 20% of your tire leaked out. Now you refill your tire with air, you'll now have 96% of your tire filled with Nitrogen because the 20% you filled with consists of 80% Nitrogen (80% of 20 is 16). Fill it a 3rd time and you'll be up to 97%.
