I seriously question the authenticity of some posts.............
With that said:
I'm not downplaying the issue by any means and I personally feel for anyone who's had/having vibration issues. I hope the matter is finally figured out and resolved.
When I purchased my truck earlier this year, during the test drive, there was a noticeable shake/vibration. The salesman stated that the tires probably were out of balance and it was sent to the service department for repair and another test drive before purchasing. After I test drove my truck again, with no shakes or vibrations, I asked what was wrong. Salesman stated that the front driver side tire was out of round and needed to be replaced. They replaced the tire immediately and the shake/vibration was gone. He also said they've seen this issue more than once, new trucks arriving with bad tires that needed to be replaced before being sold.
I've since had no problems in 7000 miles and don't anticipate any. It was a noticeable difference when the new tire was installed. BTW, my truck was ordered with the optional 22's and Bridgestone Duelers.
