I could be wrong, but its looking to me that these tires are not being mounted properly.
With tubeless wheels, mounting is much more critical and a PITA.
I've learned the hard way to:
- put soapy water on the bead when mounting
- pump the tires up to the maximum allowed pressure and let it sit for ~5 min
- look at the entire rim to ensure the tires have "popped" on the rim properly
- deflate, and reinflate (probably with the valve stem in this time).
If I don't do this, the tire often will not pop onto the rim properly. Looking closer I can see that most tires have a little extra layer of reinforcement at the bead. If I can not see this reinforcement all around the tire, that means the rim is against the sidewall of the tire, not against the reinforced bead strip, and problems will occur. And with hooked rims, I want to ensure the bead is evenly in the hook (it can be too low or too high, depending on wheel design)
Often I'll just put the tire on with a tube for a day or so, to ensure it is unfolded and in the right shape.
