Hi Chris,
I think you may have a couple things going on at the same time depending on vehicle speed.
First would would be to zero in on tire balance. Then I would recommend that the dealer do a powertrain neutralization including loosening the exhaust at the manifold. Lets see what that produces. What I am also suspect is a driveline 2nd order but it is not all that bad compared to the wheel tire. Do you have aftermarket wheels and if so are they hub centric? These kind of problems are what we faced most times in NVH...it is not just one thing where you find the magic bullet.... Patience and determination are your ally here...
Good Luck!
Best,
Phil
