I blew my first wire-bead Pasella off a MA-2 rim...twice. The first time I heard a boom from the garage, and found a slime mess all over the back of my LHT. I mentally kicked myself for a sloppy mount job, cleaned it up and remounted carefully checking around both beads that the tube was interior. Later that night...BOOM! That was earlier this year. Gnashbar replaced the tire for me, but I won't buy wire-bead Paselas again.
In case you question my methodology, I have been mounting clinchers since the early 70s with only one other blowout (that I can remember, hey early onset of A at 52!), a folding RuffyTuffy that I put on in haste not checking bead seat.
