Mpg Change From Rft's To Nonrft's?
Many on these forums have changed from OEM run-flats to nonrun-flats. Michelin Pilot Sport A/S Plus appears to be a popular option to maintain sharp handling. Has anyone noted a fuel economy change in going from factory OEM RFTs (Goodyear NCT 5s in my case) to the Michelins? Better or worse?
