2017 Porsche Macan Tires

I bought a set of these for my 17 Porsche Macan GTS AWD. They do terrible in the snow so I'm not sure why they call them All Season, 3 season at best. I've put less than 7,000 miles on them and the rear tires are BALD now. Yes my alignment is fine. I never saw a tire that went bald that fast in my life. We realized this when my wife almost spun out going over a puddle last week. I was't expecting a miracle tire for this price but expected them to last more than 7,000 miles. Cannot rotate tires on the Macan due to different size on front and rear but these tires wore evenly just the same, they just are BALD now. My advise...................Do not buy this brand of tire unless you don't value your wallet or your life.
