You gotta love the 'net, 180° disagreement (as usual).

I attended a seminar on rigging, hoists, chains, cables, etc some years ago. A question arose on whether someone could weld a hoisting hook onto an item instead of bolting it. After some discussion and naysaying from some 'experts' in the crowd, the final response of that factory rep was 'Do you think you know more about our products than we do?'.

I'm sure this comment will anger the folks driving on this tire setup, but I would trust the tire manufacturers recommendations more than the heresay of individuals that may or may not have the same car, same vehicle weight, driving habits, judgment, etc, as you.
