Recently aquired a 2010 Outback with standard 225/60x17 all seasons. I believe the normal -1 snow tire/wheel combination would be 215/70x16. I have been offered four almost-new Blizzaks mounted on steel wheels. They were for a Forester but did not get used. The size is 215/60x16 - a slightly smaller circumference than what I think is the right fit. Is this close enough; or no cigar? Thanks for any insight you can provide!
