I think they are Goodyears, unidirectonal V-rated.
I have head that Subaru changed the factory spec air pressure for the later year cars. I have run equal pressure front/back for most of the time I have owned my SVX. I think the original pressure specs were made with comfort/ride quality in mind, not handling-- sort of like the borderline underinflated Firestones on the Ford SUVs. Higher pressure = better response, but harsher ride.
