Well...I just got in from a drive in about 3-5 inches of ice covered snow.
THESE TIRES KICK CONTINENTAL ***!!!
I was really impressed with the level of grip I had in the snow. Going through my sub...on one corner I slid the rear end out without any throttle input. The fronts really grab. I think a little weight added in the trunk would help out immensly though.
As an interesting sidenote...Going down metropolitan parkway...I was in a "slowness contest" with a 'vette. We both got our as*es kicked off the line by a ford explorer!
