Today I brought the tire to my local REI, and they seated it free of charge. Brought it home, injected 2 oz of sealant, and swirled it around. 3 hours later, most of the air leaked out. The tire is still seated, so I refilled it with air and swirled it around again. Turns out the valve nut was a little loose, hopefully that's the only issue.
