Tire wobble, or something else?

GT with an enduro tire (less than 250 miles on the tire) is giving me a wobble at anything above rolling speeds. 220 lb rider, avoid drops (barely curb drop if I can help it), but I do a lot of trails/offroad. GT is just shy of 1000 miles, and I’m at 2k miles myself. Any ideas what the problem is based on the video?
