#1 Headbandwrote a review of Panaracer GravelKing SK Tire - Tubeless on April 10, 2018
Familiarity: I've used it several times
This is a great do-all tire that doesn't stray too far from the middle. When aired down to 30-40 psi the tires are awesome on hardpack/gravel. Put in 70 psi and they are a solid tire to cruise on the road. Say away from mud and this tire excels in its versatility.
Beware tire volume between brands. I swapped out a 28c Continental Grand Prix for the 32c Gravel King and the volume (circumference of the tire) was almost identical when comparing the two.
Tip for mounting: make sure the bead of the tire is in center groove of the rim, this will allow a little extra give to pull the last bit of the bead over the lip without the need of a tire lever, but it's gonna be tough on the fingers.
