I have only had these tires for a few weeks but have already driven them in a number of rainy, icy and light snow/slush conditions. The traction so far has been excellent and make my ML550 feel like it is on rails- no slipping, no sliding - they just dig in and plant the SUV firmly. In about 2 of wet slushy snow I didn't feel any slip or pull and the car cornered like the pavement was dry. The noise level on dry pavement at highway speeds is a bit loud but not overwhelming. Wet pavement traction is excellent. Once I have driven in deep snow I will update my review, but for now I'm completely satisfied with these tires and how they have improved cold weather performance of my ML550.
