Or you have a badly molded tire. They happen, had a Schwalbe One with bad-old hop in it, nothing to do but bin it in my case. Although it depends on how forgiving your retailer is about returning tires.
Rims are new-ish dura ace C24, undamaged and true, and I've reseated it a couple times today with marginal improvement.
I think you're probably right about mold error.
If so, and if Performance won't replace, will the extra material wear so the hop stops?
