Deflating should definitely NOT unseat the bead, it should require some force to unseat the bead if you want to remove the tire. I'd say you have either a bad tire/wheel combo or a defective rim if the tires just slides off the bead.
Nope…no pressure in the tire when I rolled it. Never occurred to me that a bead could come free with that little force put on them. I ever so careful rolled the bike 6 feet. I broke the bead on the rear tire by simply touching the sidewall when I was injecting the sealant into the stem.
In some of the videos I watched….there was a loud POP when the beads seated….and in other videos the beads seating sounded like crinkling paper. Don’t know if that had to do with the tires themselves or the design of the rims.
Mine def sounded like crinkling paper when they seated, but if pressure went down too far before I got the presta valve in….the bead would pop off. In theory….a tire bead should NOT dislodge just because of low pressure(tire was hanging on a bike stand).
