It's not broken cords. I've had that happen before (on one of these same Kendas, in fact) and it's not that. I guess it might be a seating problem, but I've tried a couple of times to get it to seat properly, and have gotten the same out-of-round result every time. Plus the tire is mounted on an old non-hooked-bead araya rim, so I would think it should seat easily. I have always run tires on that type of rim at about 75 psi with no problems, so that's how I've been pressurizing this one. But if I reduce the pressure to 60, the tire gets acceptably round. To me, that argues for some sort of manufacturing defect in the tire. But who knows? Is it worth spending this much time agonizing over a $9 tire?
