I'm trying to decide whether to invest in snow tires for my new leased A4QMS with Sports pkg. I have 3yr 45,000 mi lease. What mileage might I expect for the Z rated Dunlop tires. I wonder if I would wear out both sets over the 45K miles. Are the Z rated tires really that bad in snow? I live in West Virginia---about the same climate as Cincy or Lexington Ky--- sometimes lots of snow, sometimes not much.<br>
