Is it possible that one specific tire type can never seat correctly on a specific set of rims?
It's possible that one specific tyre can never seat correctly on a specific rim. Sometimes something gets missed by QC and an out-of-tolerance product makes it into the supply chain.
Old fashioned rims like ZAC and Andra series are particularly poorly suited to tight tyres (e.g. TL/TLE/TLR styles) at low pressures.

Looking for a bit of help as I have very hard times seating my tires on my rims.
I use the same tire on both of my bikes (Schwalbe G-One Allround), but I can not get to seat it correctly on both of my wheelsets, which have rims from Ryde (Andra 40 and ZAC 421).
Therefore on some places of the tires the bead seems not hooked into the rim and "plunges" below, which creates wobbles. I rode it "as is" for quite some time, but noticed it had damaged the tire flanges on my bike with the ZAC rims.
Today I changed the damaged tire on this bike, and tried another wheelset with Velocity Atlas rims, and it seems to seat correctly. Will see tomorrow if it remains seated.
Then, I deflated the wheelset with the Andra rims, and re-inflated with soapy water and high pressure with the floor pump, which seemed to work to seat the tire, and left it like this for about 30mn ; then de-flated it to the pressure I ride and it seemed to have remained seated correctly so I was happy. But I rode it tonight, and after 25km, the tires "unseated" again, plunging on one area of the tire.
Is it possible that one specific tire type can never seat correctly on a specific set of rims? what else could I try to get it to seat? Do I need to consider different tires which would be a pain, as I quite like the G-One Allround
