I’d like to try my Gravelking SK 32mm mounted tubeless to some H+ Son Archetype rims.

The tires apparently are good to 55psi as long as they are on tubeless ready rims.

The Archetype aren’t officially tubeless ready but according to what I’ve read on line, many have used them in tubeless setups.

My my questions are:

Would Stan’s tape and valve stems be enough or should I use the Stem/ rim strip combo?

Im a big guy and with tubes, I’m running about 80 psi in the rear with some pretty good “flattening” of the tire, but no pinch flats.

Is 55psi a realistic pressure for this kind of weight?

Thanks.
