This is the worst tire/rim combo I've yet seen. The only tire levers that survive its tightness are heavy-duty solid steel levers with no plastic cladding. Of course, this will put some nice big gouges in the aluminum rim while wrestling with the tire, but it sure beats snapping expensive clad tire levers.
I thought the Kool Stop Bead Jack was an infallible way to install tires on difficult tire/rim combinations. Not so, apparently. Now I'm nursing a shrapnel wound from the fiberglass-reinforced plastic that exploded under load. Funny when a spoke replacement and wheel truing is much more straightforward than removing and replacing a tire to access the spoke bed.
Just wanted to register this comment in a searchable place for anyone specing out a 590mm wheelset. Comments or other bad tire/rim combinations welcome.
