Rotated tires now steering wheel shakes?

Usually when the steering wheel shakes badly while driving it could mean a few things. If it shakes only when you are applying the brakes, this means you have warped rotors and they will need to be turned or replaced. If it shakes just while driving, it could be that you have 1 or more tires that are unbalanced. Check this first before proceeding. It can also indicate that a wheel alignment and perhaps steering linkage repairs are necessary.
