I didn't notice it much yesterday as I was running the pressure a little low, and thought that I might have goofed installing them. But after a careful look, checking the tubes, removing, and remounting the tires, the rear has a noticeable bump, and the front looks like the tread isn't adhered staight. I got these online in Japan, I guess $40 for a brand-new pair of Panaracer Gravel King Slicks was too good to be true. Of course the seller has vanished, so there is nothing to do but buy new tires.
In my experience with Panaracer Gravelking tires when mounting you need to inflate to max pressure or even a bit higher to get the beads to fully seat on the rim. Before you discard them give them a spin and look at the bead seat line, you will probably see it dip below the rim in couple places. Once the tire pops into place lower to desired pressure. I have a Park tool for this that makes it easier, you grab the tire at the low spot and pull.
