You have the same rims as I do. TBH the process is a bit different from normal rims…
I’ve done it 3 different ways and all worked well. They all needed a bit of faff because of the width of the rims, I had to add packing foam (Jiffy foam for me, other foams are available) to build up the rim bed otherwise the tyre just wouldn’t inflate. So in order of preference…
3) Rim tape, about 4 wraps of packing foam, then a 24 inch schwalbe AV10 split tube. Easy and repeatable but the heaviest method I used by quite a way. Most folks recommend the AV10D but the AV10 is cheaper and lighter. It’s smaller but is a perfect fit on these rims, as long as you cut it straight and clean.
2) Rim tape, 4 wraps of foam, then 4 wraps of pallet wrap around the rim to seal it, with a tubeless valve. Effective this but kind of ugly with the plastic wrap, and can be a pain in the arse to change tyres- I had to redo the wrap from scratch most times. Way lighter.
3) Rim tape, 4 wraps of foam, then 75mm PVC tape (like really wide electric tape) to seal it, with a tubeless valve. More faff to set up than 2, but more durable, you can be reasonably assured of being able to change a tyre without redoing it all
(in all cases I use 50mm PVC tape with the sticky side out, to cover the cutouts, then a wrap of 75mm PVC tape with the sticky side in as the rim tape- which happens to be airtight, but I don’t think it really makes any difference- it’s just light and cheap and colourful)
