If the problem wasn't there before, then have the balance rechecked. If it is good and the rim isn't bent, check the tire for a shifted belt or a problem with the tire itself. Also, if you want, rotate the tires to the rear to see if the vibration changes. If it does, then the alignment isn't the problem.
Let me know if you have other questions.
