: Are the 17" tires on the 323Ci better or worse than the 16" tires in rain? In general, do the higer, low profile tires perform better or worse in wet conditions?
makes the big difference. However, lower profile tires tend to be ultra high performance with a tread pattern geared towards dry weather. This said tire like the Pirelli P7000 Supersport are designed for the wet and work as well as any wet oriented tire. So, the 17" are fine if the tire is designed to work well in the wet and given that all BMW OEM tires are all-season (except the M cars) 17" should work as well in the wet as the 16".
