To date, I think these Michelins are a very comfortable high-performance tire with excellent wet-weather traction. I I don't have enough miles or weather on them to evaluate longevity or snow performance, but I have driven them in dry and wet highway conditions, and they are very smooth-riding, have great wet and dry traction, and impart confidence in their handling. They corner extremely well, wet or dry. They are a little less precise in steering input than I expected, but they have a lot more tread than the tires they replaced,a set of Continental Pro Contact all-seasons, and the summer-only performance tires on my Porsche. The Contis were old, worn-out, and noisy, so there is no real comparison there, but my impression is that the Michelins are superior. My E350 is the sport version, but I must admit that when writing this review I realized my driving has gone from spirited to average, especially in this vehicle. That said, I do have some experience driving competition vehicles with slicks, and Minnesota gives you a good opportunity to practice your car-handling skills, so this review is not entirely uninformed.
