haha, yeah i’ve seen that. 100 isn’t over the max in this case.

Not being there I can't say what went on by who but a real common reason for a tire bead to sit too high in a spot is from the tube being caught under the bead. Often simple deflation and minor tire/rim manipulation then reinflation will correct this. To an inexperienced eye watching a pro handle the wheel might not seem like a "repair". BTW was that portion of the bead that wasn't seating properly also right at the valve?
…
Of course there's always asking the person who just inflated the tire with good tire seating. Did you ask them? Andy
yeah, my thinking too - if it’s not right, don’t add more pressure. that said, the tube definitely wasn’t between the tire and the rim; i could clearly see all the way around the gap between the tire bead and the edge of the rim; but no amount of squeezing or massaging the tire was going to “push” the bead down into the lip. i did ask the tech at the shop, she just said “those wheels are sometimes fussy and need more pressure to seat.”
of the 6 or so times i tried, maybe four times there was a high spot at the valve. 4 or 5 times there was one somewhere else. once there was only one, not at the valve.
the whole rim-tire-tube system seems really ******, but i guess people acquire some sort of diffuse experience/knowledge about it that makes it less of a PITA.
