Some of this is IMO debatable. Without rider weight being known that is. Traction - I'd say this depends on how much deflection/deformation of the tire there is into the road surface (due to the rider's weight) and there's probably a an ideal -- I suppose running at 30psi would offer oodles of 'traction' - but that's not viable for other reasons. So a heavy rider's 110 psi might offer same traction as another's (lower weight) 90 psi, etc.

Not sure what 'ride quality' is. If just 'comfort' then maybe. If it includes high speed handling/cornering, or avoiding pinch flats, then again, rider weight input is a necessary variable.
