At the time of this review, I'm only 1/4 way through the first winter on these new tires. So far so good. But only time will tell. This is my first impression:
very quiet (max speed reach so far: 120 km/h)
pretty sticky on most surfaces
As for handling, I drive a Prius. It's pretty sloppy with or without the tires.
If you don't drive a Prius, my review will most likely not be helpful for you.
