Getting a new set of shoes for the 80, can get them studded for 15 bucks a tire through tirerack (Fireston Dest. MTs in 33x12.50 flavor). Was wondering if studded is only good for snow/ice or if it helps off-road. Haven't found much through search, and it was all about ice with those threads. So, the question is, for no ice, stud them or not?
