Well.

Just got back from a 20 mile drive on nice smooth rubberized asphalt -
the surface where the steering wheel feedback is (was?) the most
noticeable.  It seems to have gone away almost completely.  I was able
to pick up a tiny bit of vibration through the steering, but that may
have been due to the fairly well worn tires with which I was doing the
testing.

Next step: go talk to Discount Tire and see what they have to say.
