You can't go wrong with Hakapalita (they invented snow tires). I would not run staggered but if you must the Haks are "All Weather". I run stock type 17" 255-55-17 front and back for winter. I don't know of any quality winter tires-mainly hard rubbered hockey paucks with some open tread. Also the low profile do not conform to road bumps as well as 55 profile-and then the biggy- the worst possible tire for snow is something really wide and hard like low profile.
