Too many variables to consider including riding style, road types, etc. Experiment. I will say, from my experience and dealing with others most run way more pressure than is optimal or required. I try to run my bikes at the lowest pressure that won’t roll tire or strike the rim during normal riding. Naturally there are objects in the road we can’t account for so it’s finding the balance that works for you. Lots of information exists on the interwebs related to tire pressure, start low, and work your way up.
