Saab made a big thing at the time that the aero 3 spokes (and the aero
body kit) made a difference to top speed because of aerodynamics (not
weight), compared to a steel or standard alloy shod car with no kit.
I would suggest looking for a set of 16" 9000 Aero 3 spokes for the
summer on a later 900, with decent tires on, and fit winter tyres to a
set of 15" steels for when the weather is less clement (and/or if they
salt the roads locally to you). Depending on the weather extremes where
you plan to travel, you might find two sets of all season tyres in the
different sizes/profiles/widths might be better than a set of wide
sticky summer and narrow soft winter tyres
