I know the OEM size is 225/45R17

Anybody downsized a bit on OEM 17 in Mini wheels (7Jx17)?

Something like 205/50R17?

My 2016 Clubman came with 205/55/16. Have also seen 195/55/16. So if you can get some 16s......

yeah, though about that too. But I'd like to get 18s (wheels and tires) for next summer, so thinking of keeping the OEM 17 for my winter setup
