I'm on my second set of Cooper AT3s in 10 ply. I got 40k miles on the first set, but I'm horrible about getting them rotated, and all my miles are in town, unless I'm towing. I've got 12k miles on the second set, and they look new.
They ride better than the wild country's I had, and were much quieter. Good wet weather traction, and good dry. I'm in Georgia, so they have only seen snow like twice, and seemed to do well, but not an expert on that.
