Thing is it separated as not a drive wheel too. But I will rotate it into the back i dgaf lol.
My belief is that the faster you run these wheels the more this problem is likely to happen since the rotational force is stretching it open at those edges so as it’s compressed on the road surface it’s flung back up. Not that it should be an issue and not that 30km won’t do it, also weight dependent I’m guessing.
My diagram of this with the hollowwheel since it shows the exaggerated flat spot happening on the ground:
