These were the stock tires on my vehicle and drove extremely well when new. While I had no problem whatsoever breaking the rear loose in a straight line or in turning situations (even at speed!), skid entrance was predicatable and controlable. The vehicle turned in very good lateral accerleration numbers (measured). Beginning at 50% treadwear, performance began to drop off dramatically, until even on dry pavement it feels as if I am driving on marbles. If not for the electronic traction control (I originally NEVER used this feature) I would be afraid to drive the car with these tires installed. With 1/8 tread remaining before the wear bars were exposed I was driving a Jet-Ski when it rained! I will NEVER purchase a set of these tires, opting instead for RE-11's, Continental DWS's, or Michelin Pilot SS's (which I'm buying now). I have driven vehicles with these tires installed so I do have a baseline to form an opinion from.
