Nope John, with due respect, I beg to differ.  Maybe the nuts you are
referring to are for the BOLT on wire wheels.  I could see where these
might be different (I have never actually seen a set) The nuts for the wire
wheel ADAPTOR require no more torque or holding power than the standard
steel disk wheel, as they bolt to the same place with the same lugs.  The
loading at this juncture would be exactly the same as a steel wheel.
However, the "vertical" clearance is limited.  If you look at any picture
of one of the kits offered for wire wheel replacement you will see that the
lugs are indeed beveled on BOTH sides for the clearance I mentioned, and
are only about 1/2 inch in length - If you have access to the cross
sectional picture, that are in several of the service manuals of the front
wheel assy with a wire wheel attached, you would also see just where the
interference would be if the nuts weren't beveled.
