There are certainly some tricks to make tubeless setup easy. First, if it’s a new tyre, it’s often worth unfolding it and leaving it round overnight before fitting. Always take the valve core out. It’s normally too restrictive getting air in fast. Get a spray bottle of soapy water. Get the tyre one the rim, then go round the bead getting it wet and bubbly. A track pump is a must, high volume preferably. Pull the bead out as much as possible and hang the wheel on a hook to stop the bottom deforming. Pump like crazy and the tyre should start to crack onto the bead with scary banging noises. If it won’t, see where the air is escaping worst from the bubbly water and straighten the bead. CO2 is an absolute last resort but works. Get the tyre up to 40 psi and it should be fully seated. Now pull the pump off (all that precious air will escape) and crack open 20-30cm of bead to pour in your sealant. You do it now so it doesn’t spray on the floor when you first seat the tyre. At this point one bead should be happily seated and 3/4 of the other one. Turn the tyre 180° so the sealant runs into the sealed area and refit the bead. Reinflate to 40psi. Get the valve core ready and pull the pump off and pop the core back in fast and you’ll still be inflated. Give the wheel a good shake and roll it about to get the sealant everywhere. I can change a tubeless tyre pretty much as fast as a tubed one now. Oh, and get the lid off a paint can to scoop the old sealant out of the old tyre and put it in the new one if you’re saving it.
