Exactly the same problem. 2005 MN6. I've tried everything and it only happens (for me) when cruise in gear. Stops immediately when I push in the clutch and doesn't happen if I rev the engine then.It acts to me like a bad U joint in the driveshaft which obviously Corvettes don't have, but just guessing here it does have me thinking torque tube.

Not trying to argue that it is not the tires, but just have a discussion. Why would the problem stop if you push in the clutch and it goes away. Further if I go ~80+ does it get smooth again. I would think tires would not be harmonic and would always cause the vibration at any speed.

It my case it feels like the entire car, rather than a single area. (Definitely not the steering wheel). I can easily see the vibration in the rear view mirror. It is about BRrrrrrr - two seconds - BRrrrrr - two seconds etc. The first time I felt it I thought it was small ripples in the pavement.
I appreciate all the comments so far, it makes me think beyond my own ideas about the problem. Keep them coming please.
( Just thinking out loud .... since the OP has a automatic, I have a manual, and assuming its not the tires the only thing we have common is the torque tube. I've ordered new guibos and bearings which I should get in a week. Maybe when I take it apart I'll know more ---- if the torque tube is the problem

Not to be a smart ... but maybe take it to a trusted mechanic. Or at least have someone who has a good knowledge of cars drive or go on a ride with you to narrow it down. You didn't even know that shifting to neutral has a similar effect to pushing in clutch.

Also tires ca vibrate from things like separation or nonuniform wear not just being out of balance.

I had the exact same problem. Seems the previous owner had put fix a flat in the right rear . No way you can balance with that crap in there. Replaced both rear tires, road force balanced and smooth as silk.
