You could do either studs or chains...or look into a really good A/T tire, or even an M/T tire..some say that M/T's aren't good in the snow because of the open tread pattern not holding any of the snow...but I used to have Kumho Venture M/T's on my Wrangler, and man, they were bad ass in the snow...we had about a foot of snow last year here in Richmond, and it was like driving on dry pavement....
