| | c6 17x9.5 wheels from OE wheels
I'm asking the question for a friend with a v6 fiebird. The car has the 16" snowflakes with 225s from the factory.
He brought up something I couldn't answer, but the question is does having a bigger wheel 17 or 18s with smaller sidewall kill his mpgs significantly.
Also what is the "minimum" tire can he put on 17x9.5 wheels since he doesn't really need 275s.
