I had my tires rotated and balanced today. The shop doing it does an excellent job. Now I've got a shimmy in my steering wheel around 55 mph. Is it possible that something is wrong the rim? But wouldn't this have showed up when they balanced the tire?

Thanks,
Matt

You could have s slipped belt or other condition which would still allow the tire to 'balance to zero' and still cause shimmy.

Go to a shop that has a Hunter 9700 Road Force Analyzer and have them Road Force the front tires. Not cheap but this machine actually has a roller that pressures the tire/wheel assembly as it's rotating and measures where the tire is imparting unnatural or uneven force against the roadway which is the primary reason for non-balance related shimmy.......

was the shimmy there before?
may be a warped rotor

Thanks for the quick replies. I never felt the shimmy in the steering wheel but this may be because the wheels were in the rear. Slipped belt sounds like a possibility.
