Looking to replace the tires on the Family Truckster – a.k.a.: 2012 Countryman S with OEM wheels/Sport Suspension on an All4 Manual. Wife works in the medical field and some hospitals aren’t in the best of areas. Occasionally, she works nights as well so she wants to keep run flats. Can’t say I disagree. She’s a spirited driver so I’m looking at something a bit more performance oriented than the OEM tire. The OEM tires were OK at MOTD last year, but I’m looking to improve the handling. In looking at tire sizes, 225/45-17 seem to be a bit too short compared to the OEM size of 205/55-17 while 225/50-17 seem to be about spot on. Anyone with experience running 225/50-17? Michelin Primacy MXM4 ZP (runflat) in 225/50-17 are at the top of the short list.
