How about verifying the runout yourself. Jack it up and make yourself a pointer if you can't get a dial indicator. Slowly rotate the tire with a gap at first. Check on the outside corner. You can then try loosening and tightening the high spot on top or rotating the wheel or the spacer on the hub a couple holes. If you can get things better you should notice a huge difference. A little bit off center makes a huge out of balance force. I used to go to a tire store tha balanced on the vehicle. You'll feel out of round at some speeds anyway, the stiffer things are the more interactions you'll have.
