I had some  5 year old Nokians on my Syncro , that I ran a tire low and the wires were coming out if the sidewalks as well .
        I really liked them, very aggressive and quiet at the same time.  
       Mine were Hakka C as well, I replaced them with 15" ones from Van Cafe and they are nice as well, more of a snow  / street tire but with front and rear lockers I should be OK .
