If a bushing is bad, the play in it can cause vibrations. If it a steady one, at 50-60mph, and there are no signs of tire tread seperation, then out-of-balance tire can cause it.
If it just 'showed up', then tire tread seperation is a very strong posibility. Jack up the tire and place car in neutral, then rotate the tire by hand while looking closely for a 'high' spot in a section of the tread. Usually about the size of your hand.
If oyu can't find the problem, put the back tires, one at a time, on the front. Test drive to see which tire it might be. Then do other tire.
