So I mounted this tire tubeless on Sunday. Everything went great. I took it for a short spin around the block to make sure everything was good. Tuesday came and I took it for a proper gravel ride. Now when I mounted the tire the valve stem was directly under the SK+. When I got back I noticed the tire had shifted about 2 full inches. There was no loss of pressure and no sealant was leaking anywhere. Anyone else ever see this?
Eventually a mechanic used some dabs of RTV on the bead to get it to hold in place. I never felt completely comfortable doing fast descents with that tire, and I never bought a Panaracer again. Which is a bummer, because I liked them otherwise.
Just an update. I took it for another ride the next day and it shifted another inch or so. But again, no loss of pressure or sealant leaking. So I aired up the tire to about 10 psi past the recommended max and let it sit for a few days. Lowered the pressure to riding pressures and I've taken it for 3 more rides and it has not moved anymore. Fingers crossed.
The GK has a pretty loose bead. I stopped using them because they are hard to get the beads to seal on my rims. If it’s slipping you need to add more wraps of rim tape to make it tighter.

I have exactly the same issue with GravelKing tires. They are just too big for any of my rims. I have had good luck with Continental road and gravel tires...they are pricy, but they have great ride feel, good traction, very rugged (rarely puncture that the sealant can't handle), etc.
I also use the Specialized Roubaix for the winter as the traction and durability are great.
I have two sets of GravelKing tires that between them have (if I remember clearly) 7 or 8 patches.
