If you’re mounting up on nexties 65mm rims, you’ll be able to use something like gorilla tape clear (though I hear some people use parcel tape – I wouldn’t like to risk that myself though). the 80mm rims require a bit more finesse – typically either a double wrap or using stans over the holes and gorilla tape clear (or another waterproof duct type tape) down the middle. This is just because the holes are over to the side and so you don’t quite get the coverage you need with a single wrap of clear – and normal gorilla tape is just too wide (think it’d probably be fine on 90mm rims though).
And for reference, 45nrth van helgas on the 80mm nexties are about as tight a tyre/rim combo as I’ve ever used. Especially getting the damn things off. Go up tubless pretty easily though.
