The bikes I have use two different size tires: 7:00x23 and 7:00x38. My nominal weight is 190 pounds. I ride on really rough roads and often encounter glass and other sharp things on the road. I currently use max tire label air pressure with no problems but if a lower Safe pressure would bring more comfort I'm all for it.
What should I run in each bike?
Here is what you do, pump the tires to 4lbs short of the max, so if the max is 100PSI, try 96, if that requires too much effort, then try 98, if it still requires too much effort try 99. If 96 is okay, then try 92, you keep going until you find a pressure you like. Do both tires together, once you get a number, go 4lbs less on the front, see how that goes, once you have it down, those are the pressures for that bike. Note a couple of things, if your weight average changes by more then 5lbs or so, you should redo the experiment. Each bike needs to be done separately.
