The rule of thumb I've heard is tread is useful in terrain where it will leave tracks. Mud and dirt, perhaps snow, but not rain. I say perhaps snow because snow can also involve slippery ice, where studded tires come in quite handy. Over winter I run Nokian A10's, but that's just for the occasional ice I wasn't prepared for, I don't ride if there's a forecast for snow/ice.
