The discussion about the nose wheel reminded me of a thought (well; even
a little analysis) I had some time back but never mentioned here.  My
tentative conclusion was that the tendency for nose wheel shimmy could
be caused by; or at least exacerbated by, the relatively square shape of
the traction surface of the tire used.  Looking at the forces involved;
seems to me that the right caster angle and round tire face should be
much less likely to shimmy.  Has anyone tried a "round" tire, like those
used for most tail wheels?
