This is the third set of Yoko AD07 or AD08 I have purchased for my Porsche. I am a track rat, but have dedicated tires/wheels for the track. This is my daily driver, and is driven 50% city, 50% highway, including in the rain. These tires are fantastic with the best dry and wet grip available in a street tire. The turn-in is sharp, but not quite as good as Michelin PS2's, and better than Dunlop Direzza's. They are predictable at the limit, with a very correctable breakaway point. They are fantastic in the rain, and I have driven them in a downpour at Watkins Glen track, with absolute confidence. Resistance to hydroplaning is excellent. As they wear down they get VERY loud as they near the wear-bars. The wear is about average for an extreme performance summer tire. I just bought two AD08=R's for the rear after 12,000 miles. Fronts last me about 18,000. I don't care if they don't wear like iron - they are that good!
