There seem to be just two OEM summer tires that are delivered on M Sports in the US. I've read that the Pirelli Cinturato P7 Run Flat are a bit more inspiring than the low rolling resistance Goodyear Efficient Grip RunOnFlat. Now that A/S tires are an option, any reports on what tire is being provided?
Please comment on your impressions of the OEM tires.
