I have snows from a 1994 Saab 900S 5 Dr (15 inch steels, 195/60-15 Pilot Alpins). About to get a new Legacy SE Wagon - and I was curious how I could determine if the snows would fit/work on the Subaru... they both appear to have the same 5 bolt pattern - but I would imagine there's more to it than that...

 

I think I was able to answer my own question. Looks like bolt pattern is different 100 v 110, and offsets are different as well - so I'm thinking this won't work.
