I spoke to my BMW mini dealer this week and you can fit a 15" wheel to a R53 (2002) Cooper S providing you don't have the JCW brakes - which need more room. I have bought some mini 15" wheels on e-bay and am having winter tyres fitted this weekend (195/65/15 - original wheels have 205/45/17 so very similar). Will post an update once fitted to say if dealer was right! Going smaller I am told will not only give more grip (as thin tyres are best to cut through snow) but cost a lot less as aren't run flats (I am paying Ł200 for 4 fitted).
