Thought I'd add my own experience so far. Have just mounted a Schwalbe G-one 35mm on a 17mm internal Alex disc rim. Used two layers of Tesa 19mm tape (which I read somewhere is the same as Stans) which fit snugly right up to both rim walls. Tyre went on with a bit of encouragement from tyre levers. I was a bit concerned about the tyre seating around the valve due to a lack of space, but it easily got to 60psi first time with a track pump and looks to be staying there. Didn't hear a reassuring 'pop' as it seated but it looks like it has and it's holding its air. Can I put sealant in now and ride it tomorrow morning, or should I wait till the morning to seal - and can I then ride it straight away? Ta!
