What about nitto mud grapplers, I run them on my krummie. They do great in the snow, I've drove it around my muddy pasture in winter fixing fencing and they seem to keep clean. I haven't wheeled them these are just the characteristics I've noticed from being on a work truck. They are gaining popularity with the rock guys in my area. I'm probably going to run these on my buggy and just use my reds for comps
