Wide tires in snow and slush are a 'no no' since they tend to ride up on top, reducing control... paradoxically this is PRECISELY what you need in soft sand.

Reduced pressure in ANY tire will increase the contact patch- just physics. 30 psi with 900 lbs on that wheel = 30 sq in.... take that same 900 lbs but with 20 ps... 45 sq in. Not that simple, but illustrative. Releasing air will increase the patch in bothe length and width.
