60 PSI in an E rated tire is fine provided the tire is not loaded beyond the manufactures pressure/load rating. The side wall pressure is for the tire at maximum load. So weigh the rig and air the tires according to the actual load with about 5 PSI as a buffer, but not over the max pressure per the sidewall.
Over inflation for the tire load will cause premature wear in the center of the tire.
