I highly recommend the Michelin P4 if you are interested in a very high performance winter tire. I run the Michelin Super Sport as my summer tire, and these are every bit their equal in cool dry weather, and with less tread squirm. Amazing! In 10 deep, relatively dry snow, the traction was superb, no loss of grip under power or brake. Yesterday, in 4 of packed, snow, ice, and slush mix, the car floated a bit more than our FX 35 on the Blizzak LM70, but the start/stop grip was very good, even in these poor conditions. Dry and wet cornering at speed is outstanding. I am quite happy with the tire.
