@DomOfTheDead, I can see all those tires being great for clay and silt (swamps, deciduous forests with a lot of leaf detritus) but out here and in moab (fine to course grain sands up to cobbles and boulder size rocks as well as sandstone slabs and igneous and metamorphic slabs) I think they will falter. In my opinion, a tire with more surface area and tighter lug pattern will excel at holding to the surface of slabs better than a lug that will flex and chunk. They will also stay on top of sandy surfaces better instead of digging down into the sands. Where people with KO2s were crawling up the slick rock sandstone in Moab, I was chirping and slipping with my KM2s and 3s.
As far as snow, the big lug tires will perform gray at chewing through heavier snow and drifts like paddle wheels. If there is a crust thick enough to hold up a truck, those will likely break through and you will be fighting axle and frame drag. Just my 2 cents.
