Nokian W100's, 40-622, both tires at about 40 - 50 psi. If this winter is like the previous two, there will actually be minimal snow on the roads most days, and the studs are just to keep the shiny side up when I hit the few places where there are usually ice patches. This is for 8 mile round trip daily commute on side streets and MUP, relatively flat terrain. Pretty tame ride, just don't want to get wrecked.
