Yeah, it's defo looks like the same rim, so 65psi max according to Yishun. They do say it's good for road use too, but I would suggest this is a pure gravel/CX rim.
The rep from Xiamen just came back to me and suggests it's 90psi maximum...
I've update the OP to reflect the max tire pressures
Must be 65psi then. I was just going of the label, but I think they're generic...
