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.
