Quick question. I've finally managed to get my gravelkings on 650b rims. Pumped them up and the beads made a satisfying popping sound. I've not added the sealent yet as I'm off to Poland on the weekend and figured I'll do this when I'm back. But, to my question. After mounting and pumping last night, I found the wheels this morning deflated, though the tyre bead was still in place thankfully. Is this to be expected since there is no sealant in there, or does this point to some fault with my mounting? When I first pumped in up I didn't hear any air hissing out from the valve or anywhere else.
