I had the ATZ on my last tire set, it lasted me nearly 50k with many burnouts. Loved those tires but they weren't that great in the snow, alright in the mud. It was best in sand and paved dirt. Although they had issues with the tire separating from the bead, it happened to me. I had 2 blow outs with those tires though, the last blow out was while I was towing that caused an accident. I think that is the reason why Mickey Thompson stopped making them, they had quite a bit of complaints from customers having a tire blow out after few months of driving. It was a design flaw then they fixed it a while after. They were great tires that lasted a long time but had issues. They are quick on warranty.
