I had a terrible shimmy @ 55 until one fine day when my right rear tire
exploded. The tire had been on the car for about 8-10 years and the shimmy
was
there for all that time. The tires were Michelin radials and were inspected
many times over there life. Since they were new I assumed that the problem
originated else ware so I changed the wire spoke wheels and spindles, as well
as
the entire front suspension including the wheel bearings. I also inspected
the entire frame for defects when the car was being restored. Nothing helped
so I figured that the skuttle shake was here to stay. After the tire explosion
(incidentally only the tire blew not the tube) I replaced it with the spare
which is not a particularly high quality tire. Guess what the car no long
shakes. I have now replaced my Michelins with a set of Cooper tires and have
almost zero skuttle shake.
