Driver's side.., passenger side? Both? If determinable to just one side go to tire shop for removal, and get a spin test. It just might be an inner belt failure causing a Hop.
Your wheel lug hole(s) could be wallowed out a bit, but that would be too obvious, and the tire person, or you should have noted that easily upon installation.
I have had such a belt failure, and it causes a "Hop", or a slight bounce, rather than a wobble. I too had rotated front to back, etc., and once removed from under the 350 engine, to the lighter rear end produced the same issue.
I have seen wheel(s), (no matter where positioned), where not all the lug nuts were not on tight, i.e., some were, and some were not, and thusly the tire/wheel would "Wobble", causing a slight side to side motion as the result, rather than an up, and down motion causing a hop.
