For anyone else out there with Grand Bois Hetres, how the hell do you get them to seat properly? I can't for the life of me get the bead properly seated... there's always at least one "flat spot" where the tire tread dips low when you spin the wheel (radially untrue), and where it happens corresponds to a section of the tire where the bead line dips down below the edge of the rim. It's almost as though the bead is too small for the rim (although, it wasn't hard to mount on the rim). I've practically gotten blisters on my hands from pulling on the tire in all directions trying to get the bead to pop in place. I've tried pumping it up to 85 psi to no avail. I've tried remounting the tire, no good. It's the same with both front and rear wheels (Velocity Synergy). Any tricks I should be trying?
