I had something similar happen once. Driving along at 80km/h and it felt like tires out of balance. Slowed down and then all of a sudden it was gone. Got back up to speed and it's been fine since. No idea what happened. I figured a chunk of mud was in the rim and fell out leaving a open spot and putting the tire out of balance, then when I slowed down the rest fell out and it was ok. Drove it alot since and it's still fine.
