An axle/suspension system for a heavy-duty vehicle includes a suspension assembly, an axle, and a damping means. The suspension assembly is operatively connected to the heavy-duty vehicle. The axle is operatively connected to the suspension assembly. The damping means is operatively connected to and extends between the suspension assembly and the heavy-duty vehicle. The axle/suspension system has a motion ratio of between about 1.4 to about 1.7. A method for optimizing damping of an axle/suspension system of a heavy-duty vehicle includes the steps of: calculating a curve representing a damping energy relating to load on a damping air spring; calculating a curve representing a damping energy relating to air flow velocity through at least one opening of the air spring; calculating an optimized motion ratio by determining an intersection of the curves; altering the geometry of the axle/suspension system to provide the axle/suspension system with the optimized motion ratio.
