I have never reviewed a tire on this site but felt compelled to after driving on these the past 2 winters. I picked up an unused set of these on eBay for my 95 M3 after reading some reviews around the web and have been very impressed. They proved excellent in all snow conditions that I have encountered and are in fact some of the best rain tires I've had on my car. They will simply not hydroplane at sane speed. I have driven my M3 in snow deep enough to get plowed by the front bumper and while it takes some finesse to get moving from a stop in those conditions, once underway traction was excellent.
As can be expected, these tires do reduce steering response and their softness makes its presence known through the corners and under hard braking. These tires also get quite squirmy at north of 45 degrees or so. All this is par for the course with winter tires of any make I feel.
After having my car perform as well as it did with these tires on I recently suggested a friend put them on her '12 Subaru Outback for the Syracuse winter. No snow as of January 3rd but I suspect once it does come her car will be an absolute tank.
