It is a Velocity Synergy clincher rim, with a Grand Bois Hetre (gumwall, kevlar bead, folding tire) going on it.

I inflated it to max rated psi for the tire, and that seems to have seated the bead well. There is one or two places where the witness line starts to dive a little, but I can still see it - it hasn't gone under the rim edge, so looks like it is as close as I'm gonna get.

I am hoping it will not present the same problems in the future, like after a flat fix. I'd hate to spend half an hour getting a tire seated on the road after a flat fix.
