I have been impressed with Cooper's "Mastercraft" line/label and the "Stratgey" tire. It has been on her dd Lexus ES for almost 40k miles. The tread depth is still quite good and I think they are warranteed for 60k or 70k and they will meet or exceed that it appears.
They give very good rain performance and dry. I found them lacking in snow, but you don't care about that. Another member said he didn't think they were bad in the snow. I used to live in northern Vermont so I may be ore critical in that regard. Rain is the critical thing here and they deliver on that. Some say they are like the Cooper CS series, just non-union made (rumor I heard, don't know the validity). Bang-for-the-buck, best tire I have used in that regard.
OOPS - just saw your last post!
