Yeah. And it is interesting that WS90 has pretty much the same design as WS80, but less siping. I know that lateral ice handling was an issue on WS80 (I had that same issue on DM-V2), and that is why I think WS90 was introduced soon after as a replacement.
But even with less siping, first 100 miles, I think they are more squishy than VC7, and I had VC7 in 205/55R16, while these are 205/50 R17, same car. They seem also bit louder. However, they are eager to turn, even compared to DriveGuards in 225/45 R17 I took off to put these, and DriveGuards were RFT. But WS90 seems to turn faster.
