A few more factors besides rider weight and preference are the tires themselves. A stiff sidewall or just tire volume can all affect what 25 lbs feels like. Your rim width will affect tire pressure as well. This is why percieved pressure is so important, i.e. Squish it with your thumb and then go ride it. I find my pressure by starting in the high 20’s and then slowly letting out air on the ride. In Florida sand low pressure is probably a good thing. Eventually the tire will start to squirm on turns and I’ll add a pound or so from there.
