As suspected, air is escaping from the rim joint as it's sleeved on the R460. Any pro-tips for sealing it? no amount of shaking and jiggling seems to get sealant to plug it.
It's meant to be tubeless compatible. Cover the outside with soapy water. There is a circular shaking motion you can make to try to get sealant into the place where air is escaping. If this doesn't work you could try putting in more rim tape to cover the join.
