To: Tirerack folks or anyone I have a '94 325is with standard 15" "honeycomb" style wheels. I want to get new wheels which look better and are easier to clean. I'm thinking 16" is a better choice than 17" because they would have a smoother ride and be less likely to get damaged -- but still look pretty good. When I look through your catalog, it seems there are a lot more choices at 17". Is the difference between the two sizes significant or am I showing my old age?
