Yes, the 190 wide tire, combined with almost no drop center and a GT spec making the tire extra stiff really make you work. That's where getting the tire good and warm and pinching the sides in with wood clamps are invaluable.
I can only dream I getting the same tire mileages you all are talking about
I am not sure about the K16 wheel but spooning tires is pretty easy after the 500th or so
and no removing the tire to retrieve the spoon or rim guard is not allowed to count towards your overall total LOL
