What is the tester approved tubeless tyre pressure chart/formula?
Look at what I use, reduce for bigger tyres, reduce again if the subject is lighter than I am.
Schwalbe say 80psi max for 30C G1Speed, and also 70kg max load. If you work from that and assume 10kg bike/gear and 60/40 load split you get 0.6x(92/70)*80=63psi or 4.3bar rear and 2.9bar front. I think I lean on the front a bit more than that, it depends on morphology/riding position/bike geometry. It also depends on terrain, riding style and personal preference, so whatever I say is just a starting point and you should adjust until you like it. Some people actually like making their bikes slower and less comfortable, and who am I to tell them they are wrong if they always pump everything up to the highest number written on the sidewall?

I think I'd start at 4.2/3.7 bar F/R at that weight
