I've run my K60 (on the back of my 950) up to 100 psi to seat the bead.
The thing to remember is that if the tire is rated to 60psi, the manufacturer has tested that tire to well over 180psi. I've run plenty of stubborn tires up as high as my compressor can push (120 or so) with no issues.
Having said that, I use a clip-on chuck (hands-free) and DO NOT stand over the tire while it's seating.
