I ordered them specifically for my Tacoma, in place of the original tires -- so far, very happy with them, after 20,000 miles. I have used them in snow (6 inches), black ice (slowly) , and very deep soft sand, with no problem. Also, they are smoother than my BFG All-Terrains were on my Pathfinder, and much quieter. Not sure how they would be in deep mud, though -- the All Terrains had deeper lugs.
I should add that with the new tires, I am sometimes getting 22 mpg per tank on the freeway with very careful driving. I was never able to get over 20 mpg with the All Terrains.
I am running them at 42 lb. in the front and 44 in the back, while towing.
