Thought that I'd start a thread on tires for smaller-wheeled bikes, seeing how selection is not as great. Share what you know, add photos if you can. I'll start....

Panaracer GravelKing X1 20" x 2.10"
Just spooned these on yesterday and did a mix of road, gravel, and (dry) singletrack with these and they performed beautifully. Felt quick on the road, stable on gravel, and grippy on the trail. Haven't ridden in wet conditions yet, but first impressions are positive.
