My lug nuts were at 40 FT LB after about 35 miles. The spec is 54. The Kawasaki Teryx uses the same 12mm x 1.25 lug nuts and my 08 spec was 101 FT LB I knew it was too high, my Ford F150 is 90. I set mine at about 85. The next year the spec was lowered to about 90. Honda uses a 12mm x 1.50 stud with a torque of about 98. I can see why the Viking 6 seat model has problems. The Viking rear wheels had the wrong taper, should be a 60 degree.
I set my Wolverine at 80 FT LB with the ITP aluminum wheels. I will check with my dealer to see the torque spec on the Viking special edition with the aluminum wheels.
