Does anyone have any experience in going thru wet, heavy snow? When a storm is on the way we put the cows out on a grass pasture, so the mud doesn't ever seem to get too deep, but the snow stops us sometimes. The tires I have (stock Dunlaps) float around on top for a while, but when you stop to check a calf or something, they don't seem to have enough 'bite' to get going again. I was considering either Titan 489s, 589s, or Blackwaters.
