Depends on Rims and other things
It depends also on your rim width. Wider tires seem to allow me to run at lower pressures attaining the same feel as lets say a more narrow rim at a higher pressure. I can tell you I weigh about 10 more pounds than you and run with 1-2 bags adding an additional 10-25 pounds depending on the day.
So, I can also tell you I own these and have run them from a range of 25 all the way to 80 pounds. The higher the pressure the better/faster it rolls. You can always run your tires higher than they say. I tend to do it more on MTB or commuter tires rather than really high PSI road tires. Be careful with those as they can blow easier at higher pressure, you are usually running at higher speeds, and they tend to not be as burly as winter and/or commuter tires. Its just MHO. Up to you.
