Leao LION SPORT 3 All Season 205/50R16 91W XL Passenger Tire

Had it balanced 3 times since this installation. The last time I had it done with alignment at the official dealership, Mercedes Benz of Beverly Hills. As per certified mechanic's notes - balancing was done yet challenging due to amount of weights needed to be added to the rims to zero out. On my question whether there was a possibility damages to my rims and/or due to wear and tear of my brake disks - his answer was solely it was due to the quality of tires themselves. Once thing I am happy with that I can have them rotated each time when steering wheel vibration will became intolerable and annoying and balancing will be inevitable. 275/40R18s

Had to balance 3 times already since the purchase due to steering wheel vibration/shaking at certain mph. The very last time I had it done along with 4-wheel alignment at official dealership, Mercedes Benz of Beverly Hills. Report given was 'lots of weight was used to get it balanced. Shaking will be still present due to quality of tires.' On my question - 'Could it be possible that my rims and/or brake rotors bad or slightly damaged, worn and/or possibly bent?' - the MB Certified mechanic replied and stated in his report that the condition of my rims and rotors did not correspond to vibration in my steering column, yet only due to the quality of tires themselves.
