At only 7,000 miles, these tires are already in need of replacement (2/32 rear, 4/32 front). Granted I drive them hard and I autocrossed them 3 times. Nevertheless, I did not expect them to wear out so fast. I had more competitive tires with more autocrosses last a lot longer in past cars.
Other than the short life, these tires provide excellent grip as long as it is warm. Performance starts to dip at around 70 degrees and below 50 degrees they are constantly breaking loose. On a cool rainy day they hydroplane easily. They are quiet until they start to wear out. Right now they are pretty loud.
