Similar to what honda pilot is saying, a 16" wheel may help provide better handling if it is wider. For example, if you get a 15" x 5" wheel, it won't handle as well as a 16" x 7" wheel because each wheel has an extra two inches of tire touching the pavement.I however dont think 16" wheels are rice, at all. Nothing wrong with mixing some good style with performance. The advantages of having a 15" wheel over a 16" wheel will not be enough to justify your personal opinions, especially if you like the looks of a 16" wheel better.
