I wonder how much warpage, if any, is caused buy the guys at the tire stores
cranking the lug nut torque to 80 lb/ft in a single step? Think about it,
you've got four or five lugs and they tighten one straight to 80 followed by
the rest. They get a bit miffed because it slows them down, but I stand
there and make them do it in three steps, 30 60 and then 80. Am I paranoid?
I prefer the term picky. ;>)
Am I sure it makes any difference? No, but it certainly doesn't hurt,
either. We don't run anything else held down by multiple fasteners, like
heads, to their max torque in one step. Why should wheels be any different.
Having one nut tightened all the way and the others not at all may not be
good for the mounting surfaces on the wheels either.
