I am also looking at these tires. I currently have the Michelin Latitude Tour HP's. I loved them at first. Fuel mileage was decent, road noise minimal, traction excellent in all conditions. Cant say much about ice though since I don't drive when it is icy. But hard packed snow, wet and slushy environments were just fine. No hydroplaning either.
However, they are about 3 years old now with just around 50k miles on them and they are really weather cracked along the tread line on the sidewall. I recently found a few nails in the tires. So instead of wasting any time or money with plugging them I plan to just buy new tires. I drive a lot on the highway. about 70 miles a day.
