He still had the vibration then they said that it was caused by bent rims. He had those fixed and still has the vibration. BMW then commented that the 5 and 7 series are having problems with Dunlaps and he should use Michelins instead. BMW then finishes the conversation that they are not tire experts.
I guess GM is not the only company to give the run around....
so I am sending him to the place that SGREEN suggested
so that he can get an honest answer of what is really wrong. Depending on what he finds out will determine how much he will go after BMW for reinbursement.

Assuming that the rims have been fixed properly and new tires are not out of round I would have to say it is balancing. Of course if the tires were out of round and the rims bent then it the suspension could be a problem from hitting something that I am not aware of or my friend is not telling the truth....

Either the car is aligned, or it isn't.
The wheels/tires are either balanced, or they aren't.
i wonder what they mean when he says they "fixed" the "bent" rims??

Instead of Dunlaps, he should have got Dunlops, and instead of tyres he should have got tires. 
Did he verify if it is indeed speed related or RMP/engine related? Did he have the tires load balanced, i.e. on a Hunter (GSP9700) Road Force Measurement machine? Did he rotate the wheels? They have instruments that measure the frequency of vibrations so they can pin point a source. It gets plugged into the computer and then he would drive around with it for a while to collect data. I would think that BMW would do this.

Did you think, even for a second, that I wrote "tyres" on purpose?

Nope, because you are not that jocular.
