Audi S6 e-tron Tires

I put these on my A8L 4 years and 40,000 miles ago and am now buying them again. They ran well and were not noticeably loud like some say. They also performed fine in the rain. However, I did skate a little once while descending to a red light on a particularly snowy and slushy day here in Chicago. Hard to beat the price, reliability and performance.
