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’ve googled the question already and found numerous responses that eventually turned to gibberish in my non-mathematical brain, plus posters would argue with one another about their calculations. It didn’t give me a lot of confidence.
FWIW I solve most physics type problems by 3D visualization. I mentally construct a working 3D model of the problem. I’m nearly always correct in my assumptions; I just fail when it comes to supplying the math needed to prove it.

The size(cubic feet) would be the same empty and under pressure. It does not change, just becomes pressurized.
A cubic foot is a cubic foot at 10 PSI and also a cubic foot at 100 PSI.
The math to determine how MANY cubic feet you have, I can't help you help there, I join you in the non-math part.
