New tires for my ZRX and the wifes Bandit6 this year. Did both fronts last weekend and last evening.
I have NEVER struggled with a tire the way these front Pirelli Angel ST's were resisting me. Mounting wasn't terrible, kind of stiff, but setting the beads was MURDER. Deformation of the tire in the rim during mounting process wouldn't air seal, and I had to bounce it around and futz with it a LOT. Ended up requiring an estimated 80PSI to seat the beads once air seal was made.
Mine was just as bad, but worse... when I finally got the bead seated and tossed a gauge on it, the needle was totally pegged. Straight past all markings, and buried in the zero needle (but from the backside). bled air off for a good 45 seconds before it even began to register a drop, with more to go before getting anywhere NEAR the scale.
Seems to work though. when I took mine around for shakedown run. I have high hopes that changing hers will help with the nasty headshake that cropped up last year. Probably, since I think the prior skins were likely 10 years old (with a total of a few thousand miles on them).
