John,
You probably know more about front-end vibes than me, but don't overlook the
obvious.
Those "blades" that position the front-end are notorious for causing the
problem, but I found out that the steel rod next to the blade also induces the
50-55 shake if the securing nut & bolt vibrate slightly loose. When this
happened to my car I replaced the nut with an elastic stopnut and the shakes
ended immediately.
Not to mention the possibility that when you switched from radial to bias-ply
tires you also switched wheels (or had them mounted) with a resulting change in
wheel balance.
