The warranty form going back to Michelin has the DOT serial numbers of the tires, so I'm sure they will go back and look up lot, batch, etc. They are 4614 dates codes and made in USA.

There is a feedback loop for this sort of thing. You should have had them replaced by the shop and glad you did.
As mentioned previously, runout can be from problematic mounting as well, but instead of subjecting you to back and forth with that, a new replacement was the right move.
You can also have "balance" and still have runout.
No company is what it once was. Everything is subject to a bureaucracy these days ... the best customer service is from smaller owner-run companies who keep their ear to the ground.
