its your front axles.. oh wait.. its not an e46xi.
I would have them rebalanced. at 35-40mph is odd though, you should have vibration at any speed and progressively get worse. With your winters being fine, they could have worn to mask the problem. Usually new stuff highlights worn suspension parts or bad alignments.

you seriously put directional tires on wrong?
