We've gone through all this dozens of times over the years. There really isn't any point trying to establish the 'correct' torque to use when doing up the wheel nuts, not least because they have a self-tightening action when on the road anyway. Threads of this size and pitch can take enormous amounts of torque before deforming so all that is needed is to tighten them up by hand and then give them a whack or two.
