I’ll be frank, I’m mathematically challenged. Don’t get me wrong, I can read a formula and plunk numbers into a calculator I just don’t “think” mathematically. So my question is how many cubic feet of air does one of my 235/85R16 tires hold when empty and when filled to 70psi?

I'm mathematically challenged as well, but I can help you with the answer you're looking for...
I'm a HVAC contractor and use nitrogen all the time. I get it in 100 cubic ft, cylinders (6"round X 24"high 3600PSI) I can fill all four of my 16" trailer tires from dead flat to 65# PSI with one tank. The tank costs me $10 (I had to buy the first tank then just exchange it for a full one), my two-stage step-down regulator costs about $60 and the inflator hose &connectors was another $20.
I know the word "Nitrogen" causes all sorts of controversy, but it sure works well for me. The pressure is always stable in the tires and eliminates the squiring effect of cold tires in the morning. Hope this helps you.
