If you run the 305's mentioned you can pretty much run any rim you want. But with the 309's you are only going to hook with the very best prep. If I was going to try and fit 315's I would probably run a 17X10 Billet Specialtires Win Lite. Or I would go with a Bravado Tribute with a 305/45R18 ET STREET R. It would even match the wheels you have now somewhat and the tire is taller and will work better with the 3.09's. The Bravado offset is a little better, similar to the Win Lite.
