I got together a tubeless service set and the tyres to get started. First, I clean the rims and apply the tape carefully under tension to avoid creases and air pockets. Now, I install the valves and tyres without the sealant – and only using a floor pump. OK, that was too optimistic, the tyres won’t inflate and air escapes at a million places. The air compressor solves the problem and the rear tyre seats the bead under loud plopping sounds. I had prepared the sidewalls with Schwalbe’s Tubeless Easy before, but soapy water does the trick as well. I release the air, fill the sealant through the valve into the tyre and inflate the tyre to 3.5 bar again. No air escapes, the tyre sits correctly on the rim. Wow, that was easy.
