Replaced OEM Dunlops with this tire. Have retained excellent traction qualities of old tire plus reduced noise considerably. Lexus is already quiet enough now even quieter. The tire is a little more responsive than the Dunlop but keep in mind this is a soft riding car (I have the air suspension). I expect these tires to last a while given my driving style - the LS430 is not meant to be driven hard. These tires suit that driving style very well without giving up stopping and traction ability. No issues during break-in that I have noticed. Just enjoying this tire day in and day out - I drive about 54 miles a day total for my commute.
