Subject: [CR]Ride quality

We talk about the ride quality of steel versus aluminum versus Ti versus whatever. My question is this has anyone every seen or done a quantifiable study on how air pressure or a change of tires or tire width affects ride quality. I know form experience that just lowering the air pressure 5 psi can turn a rough ride into a smooth ride and going from say a 25c width to 28c width does the same. And with the contact area of the tire being nearly equal for both widths does it matter if one go to a wider tire.. So how does evaluate a frame ride quality when tires and pressure affect the decision process so much. Charles Nighbor Walnut Creek, CA
