Started noticing some vibration at highway speeds on my 2011 328i. Dealer had it road force balanced and it got a little better, but I can still feel it. The tires have only 3000 miles on them (stock Conti RFT). One more thing that I noticed is when I drive on very smooth pavement or concrete at 5 mph I can feel a little hop on one of the wheels/tires. The dealer can't seem to find it. The wheels/tires should still be covered under original warranty and I also have BMW wheel/tire protection plan.
What else can they do short of replacing the tires? Is this a tire or wheel problem?
