I purchased these tires for an Audi A6 4.2. As soon as I drove the car I thought it was on rails. I live on the Sonoma County coast and Hwy 1 is a lot of fun when not on a weekend. The tires are extreme. I just ordered another set this evening! I like the ride, comfort, noise, I'd appreciate a little longer life but they lasted me over 2 years. I am deffinetly a happy customer.
