Best tires for this peanut butter mud? PICS

Hi I am venturing out into the goldfields of Western Australia, the mud there is basically like clay, its impossible to traverse in almost any 4×4, I am hoping that I can take an ATV out there. Even though this mud has rocks in it, I have never encountered anything like it, its like the clay you make pottery out of.

Do I need super wide tires or do I need tractor like self cleaning tires?

Example of mud:
