When did it start? Did something change then?

Was there ever a time when it was not an issue?

Out of true usually means that the tyre/wheel has wobble (side to side) rather than out of round which is what has been addressed. But this is only from my experience and you were there to watch his hands when he said it.

Out of round, out of true and flat spot can all be checked reasonably well by merely spinning the tire slowly and measuring run out.

Does this persist once tires are up to temperature? Let's say after ten miles.

What brand/model tires? How tall are the sidewalls? Or, better, what size are the wheels? Very short sidewalls exacerbate most problems.
