I'll just go and pump up gp4ks to 200psi. I'm sure that won't go wrong
It probably won't, the rated maximum is set well below the proof pressure. However, he said twice what you ride, not twice the rated maximum. Unless you're very heavy, you won't be riding GP4000 at anywhere near their rated maximum

No, it's 2x what you would run them at, ie. if 30 psi, then pump to 60 psi

"After a bunch of miles with the GP 4 Seasons I set them up tubeless, fitting René Hearse Steilacooms with one layer of tape, while Hutchinson Sector 28s needed two layers to seal up nicely – the rule of thumb being, if you can easily slip the tyre on the rim uninflated, add another layer. Once up, they held air fine. They aren't branded as 'tubeless-ready', so if you do go this route, as for any tubeless setup, be sure to perform the 2 x over-max-pressure test to ensure there's no chance of the bead popping off (inflate to twice what you ride, and leave overnight). Best do this without sealant, obvs, otherwise be prepared for a big cleanup job if they let go."

Think I might try and tubeless up the CX bike. What could possibly go wrong? Apparently they're not tubeless ready Aksium wheels. I've got tonnes of tape and sealant and my DIY inflator...
