Bought used Lexus LS430 with these CS4's on it. The tires appeared to be only a few days old. I rotated them at 6000 miles and they looked fine. No uneven wear. The car rides great with these tires, quiet and smooth. We both drive carefully because the Lexus is a huge beast, and have not pushed the car hard, except once while driving over mountain roads with lots of switchbacks. The car took these turns fine and I never heard a chirp from them. I would buy again.
