These are definitely the best overall performing tires which I've had on this car, but the tread wear is less than I expected even with a treadwear rating of 180. With only 13000 miles the wear bars are just about to show on both front and back. However, they do perform very well. They out perform the car, or at least better than I'm willing to push them. They seem to ride a little hard, especially as they get worn. I'm using Biltstein shocks. Even now when they are approaching slick, the wet traction is remarkable. I'm very pleased with the low level of road noise that they make. I've noticed that the inside tread is wearing deeper than the rest of the tread and it causes a little hunting on asphalt roads which are not perfectly crowned or flat. I don't expect to get more than 15000 miles on them and I'm a little disappointed give the cost. But, I've always wanted to know what it was like to drive the car with tires which are above the car in performance. Now I know. It's difficult to decide if it is worth it.
