there was a similar thread on honda-tech and it seemed to be stay below 40 psig or there will bad wear issues. you may want to search there under kumho, etc.
i have been starting at about 28 psig front and back cold and getting to about 37 & 33 psig on my 2150 # CRX Si in ITB. This is on 205/55-14 with 14x6 wheels.
i still have a ways to go on optimum tire pressures though.
