If the problem appears gone, I'd move on. I would avoid those tires in the future.

Curious though, did you try a road force balance with the new used set of factory wheels and what were the results compared to your old factory rims?
That is an excellent question!
these are all possibilities in my mind:

Its possible that : Tire Engineers made an error, they admitted they never moved/rotate these tires on the (road rashed) rims stating : The machine tells us it wont do any good they are too far out of spec.
.. I suppose its possible when the Chevy dealer transferred the tires they tested them on the pre existing wheels and after transfer they were good. I just dont know what they did I can go back and ask but tis been like 3 weeks now I doubt the tech will remember.
Obviously the best practices would have been to test them on the newly mounted wheels. That would havebeen my expectation, but since they still failed roadforce I should still have symptoms if those failure results were achieved on the new wheels?

On the other hand the Chevy dealer's tech really took their time with this (and I paid$$) I dont want to think it wasnt done right.

I suppose I could go back to to tire engineers and have the tires road force balance checked on the new wheels to be certain.

I have been churning through $$ though to chase down the problem.
a) 100 bucks to tire engineers to balance all 5 (including reserve) wheels
b) 200 dollars to roadforce balance at the Chevy dealer
and now if I bring it back it would likely be another 100 USD

Otherwise these are exactly what I want in tires, AT, 3PMSF, H rated and I'd like t save them or buy the exact tires again on Yokohama (if thats possible) but prior to install have them checked at authorized installer (for yet another 200 USD on me). Sigh

And they did beat these other good tires in a test:

I think if it was really the tires, even if moving them to a new set of of rims, the problem should follow with the tires. Seeing as how the tires aren't giving you any vibration issues like on your old set of factory rims, I'd chalk it to bad rims. Maybe it is slightly out of round? Some slight wheel damage that is invisible to the human eye? Could have been a defect in one of two of your factory rims that has gotten worst over time?

I looked up road force balancing and it appears you have to have some experience doing this over the years or be trained by a senior engineer/specialist to really have an idea what you're doing. I somewhat understood the procedure, but I still wouldn't have a clue to know how to do it. It appears the procedure has changed over the years due to changes in rims and tires, how they're made, materials they're made of, etc. so it's not so easy to road force balance like it use to.
