Mpg Change From Rft's To Nonrft's? - BMW 1 Series Coupe Forum / 1 Series Convertible Forum (1M / tii / 135i / 128i / Coupe / Cabrio / Hatchback) (BMW E82 E88 128i 130i 135i)

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?

I only notice a drop in fuel econ when I install my winters, which are run flats. My summers are Michelin PS3s.

Z4: RE 050 RFT to Goodyear F1 GS-D3 - No change
128i: Goodyear NCT5 RFT to Conti DWS - Very slight (2~3%) improvement
