I already have the Gravelkings on the way so find your tires a home if someone else wants them. I'll let you know about the G-One's.

Schwalbe emailed me the same day and asked for photos of the logo, said they had not seen this before except with two very specific brand/models of wheel. I replied today with the photos and will need to wait to hear what they say.

Here is a photo of how they start to bulge and deform. This was taken with a tube installed as test but they behave the same way tubeless. Schwalbe Easy Fit lubricant was used. Pumping it up further makes the deformation much worse, bulging on the side shown until they blow off the opposite side with a loud bang.
