I run a dedicated winter tire on this car, so deep snow rating is not applicable. These tires replaced a set of Bridgestone Potenzas, And I was impressed enough with the performance to install a set on my 1985 Porsche 944. They will also be the next set of tires on my 2009 Lexus RX350. Tread wear has been FANTASTIC. After 15,000 miles D W ans S wear indicators are all still clearly visible. I highly recommend these tires!
