I'm all for running tire pressures above manufacturer recommendations. I'm decidedly not in favor of running them so high that safety -- for the occupants as well as those who might encounter them on the road -- is thrown out the window. I refer to the extreme pressures - 60psi and the like - run by some folks in search of MPG improvement. There's a sensible compromise between that and manufacturer recommendations.

(Tire pressure quoted for next comment.) That all assumes that you are stopping in a straight line on a smooth road. That is not often the case in normal situations, let alone emergencies.

Note that the recommendations top out at 7.5psi above manufacturer recommendations. That's going to be in the 38-44psi range for most vehicles. A long way from 60psi.
