Tire Pressure

Just experiment. I'm 120 and ride at 100 psi on tires that can hold up to 120. I'd start with 90 psi if I were you and see how that feels.

Never go to max pressure on a tire, bike, car or otherwise. That is the upper limit. I would go, in your case, about 20lbs less than max to start. Get on it, see how it feels and how it LOOKS. Have someone look for you from the side as you go by. If it is compressing too much, put a little in. If it seems hard and you're feeling the road too much, taking into account what kind of frame/seat you have, then take a bit out. The biggest thing is to find a pressure that isn't harder than needed, so soft it won't give you a pinch flat and check the pressure at least twice a week depending on how much/how far you ride normally. If you only ride on weekends, then absolutely, check it everytime you ride. If you ride to work everyday, then every other day give it a quick check.

I just hate seeing someone riding around on 1/2 the air needed, almost on the rim. The rest of the air must be lodged between their ears.

I'm 118 pounds & I've always run on 120 pounds of pressure (20 years of cycling.) I use Continental tires. I notice more rolling resistance at less PSI.

On the often rough roads we have in Indiana, I'm willing to have some extra rolling resistance if it makes for a more comfortable ride.

Hmmm, I am 138 pounds and have kept my Trek's psi at 110. I am wondering if I should drop that to 100 and see if the ride is a little more comfy on my country roads? With my weight would 90 pounds be too low?

I keep them maxed for wear and flat protection.

My tires have an optimum range of 100-120 psi and I keep mine right in the middle of that.
