You are right of course, I was merely pointing out that psi isn't everything. Yes an equally distributed load lowers the max bending moment at the center, however load the bucket up and the machine rotated towards the front idler and you lose your nice theoretical load distribution. Throw some variations/bumps in there and you degrade it further. Of course you also get a force distribution due to the depth of the soil and the shear angle of the soil.
Would I drive over the tank? Yeah i would.
