I have the nitto grapplers..285's.. and they do pretty good in the snow considering they are not a snow tire. They have a wide foot print and big tread blocks which are not ideal for snow.

we just got 10 inches of snow last week and I went out and played a little as I did last year also. I stopped several times in the deep powder and was able to take off without spinning the wheels.

If you drive A LOT in snow then you should get a snow tire as they have excellent traction because they have very soft rubber and a lot of sipping(slits) for bite. Detroit gets snow many times each winter and I feel the nittos are fine for my use. It would be nice to have snow tires when I drive on the highway up north for snowboarding trips but the nittos are good enough because I don't want 2 sets of tires either.
