Just wanna give props to these W rated summer tires...
They are excellent in the rain and snow. I have not gotten myself stuck yet (it's fun playing in the snow again... wow, I've missed that!), and to top that off, I actually pulled an Integra out of a ditch with snow pack under my tires.
Not too shabby compared to the Kumho 712s and Cooper ZX2s that I would get repeatedly stuck in.
So yeah... I can't comment a whole lot about dry weather traction, but these excel in wet/snowy weather. Almost as good as my old Contour with cheap all season tires.
Here's a pic of them compared to the Coopers I had removed (due to a bubble issue):
