You sure the tube isn't too big and wrinkled up inside? Otherwise, if the witness line is even all around, then I say you got a bad tire.
If I couldn't return it and it rode well enough, I'd ride it just to hear the comments from other riders that get mesmerized by it when they follow.
Might be those chroniton particles getting out of phase. <grin>
