I'm new to the forum and have been reading multiple articles about tire size. I bought my son a 2012 Countryman S All4 with the sport suspension. It currently has stock 225 45 18 run flat tires and I would like to get a little more rubber. I was looking at 225 50 18 non-run flat and had a quick question. With the sport suspension being 10mm lower will 225 50 18s rub at all? Will I have to make any modification to make them fit. I've seen a few people say they will fit the non sport suspension, but not sure about the sport suspension. Any thoughts would be greatly appreciated.
