Higher pressure gives improved handling and increased fuel economy at the expense of a harsher ride. Go too high and the tread will deform and wear unevenly, too low and the sidewalls will wear and crack. Personally I run mine at the upper limit for best economy and I prefer a firm ride but it's mostly a matter of preference, it's not rocket science.
