Put soapy water along the tire bead, this allows it to slip into place without getting hung up.
I agree, 9 out of 10 tire "imperfections" are due to bead seating issues, not tire casing issues. The bead gets caught inboard of the bead shelf, and the tread is pulled down.
It can happen with tubeless rims and tires, or with standard rims and tires.
Lubricating the bead when mounting helps a lot. I use laundry soap, because the laundry is close to my bench. I just dip my finger in the half-filled cap and drag it across the bead.
It also helps to check the bead when the tire pressure is still low, like 15-20 psi. At that pressure, you should be able to massage the tire bead up into its channel with your thumbs.
