Interesting, so which is it? and how? Think about that and sort it out in your own head

Kind of chicken and egg here. Does gravel call for lower pressure? Why? Or do we need wider tires to "float" rather than furrowing on dirt, gravel, or sand? and the lower pressure follows form that change?
I offer both questions not to correct Grumpus, and actually thank him for setting this post up for me. My intent is to get people to think about how systems work on systems rather than individual elements within those systems.
IMO - engineering is like impressionist art. You have to step back and look at the big picture to appreciate the beauty.
PLEASE do not post answers to the questions above. My intent is to stimulate thought and thereby improve resistance to dogma.
