I was driving with these tires for 3 seasons already (in Lithuania). I liked them. The response on wet and dry is really good. On icy and snowy roads one cannot drive like on wet, it's obvious :) For that you have to choose at least soft compound tyres, or better spiked. They are pretty soft, which comes as a better comfort on bumpy roads. But what impressed me the most, is the wearing degree. After 20000 miles (3 winters) they are still around 6mm.

Great winter tyres, on dry these Yokohamas are like summer tyres, grip is excellent. On wet there is no problem, even a few cm of water was not a big deal but that was not with highway speed, up to 80kmph. Snow traction is great, no problem in deep snow but I had only one trip on snow in town so it is hard to say how good they are on snow.
They are comfortable, but should be better. Will buy again definitelly.
Thread pattern is similar to Continental, but I like this one more :D.
