While the winter has been mild with only one snowfall I have had the opportunity to test them in snow and freezing conditions. Simply a great tire - but you get what you pay for with these - run flat snows are not inexpensive. Most shocking was how quite the tire is in normal conditions, far less noise than the OEM run flats. I have not driven them long enough to comment on tread wear. This was one of the only size options available for the car. Handling is very good. Some slight slippage on really icy conditions, but nothing that is major. With traction control and a modest pedal they seemed to pull or push the car through the snow with ease. Backing up is very good with this tire - some snows have an issue in reverse-these do not. I would buy them again-they are impressive beyond expectation for a snow tire.
