We bought a set of these for our 2005 four door Honda Civic last month and I had enough seat time with the setup to post a review.
First off I noticed they were very quiet except on wet road whre the make a high pitched sound. Kinda weird, maybe on others cars it will not be noticable (The Civic is not the most insulated car around).
On the snow they are a bit better than average. Then again the Civic is FWD
and I'm used to drive my AWD
Talon so maybe it's just me. Same thing for the slush, I can feel that the car is pretty light but nothing dangerous.
On the ice, well :
they are very good. Good at braking, accelerating and turning. I've tried them on wet ice (around 0C) and although they are not as good as studded tire they are very good. Yesterday it was pretty cold (-29C) so I made a few test on hard packed snow and ice and they stay very good and soft at that temperature. I even feel they are better then my old cheap studded tire then I used to run on my other car.
As for durability, we only have about 3000km on these Yokohama and the tread look like new. I can still see the very little sipes on the tread surface (They are not easy to see on a photo but in "reallife" you can see it, it look my mold marking). )I will post a follow up about durabily at the end of this winter.
So far I would say they are a good buy!
We paid 89$ each (185/70/14)
