Ya know it's all in your taste and style. I like to stay in the stock size range and use the same size on all fours, that way I can rotate and get the most milage out of a set for my money. It seems that these days I get alot more milage than I used to out of a set. Seems like I don't light em up as often. Not sure if it's because of the price or my advancing age.
But man there are so many choices. When you start getting into fat, racing, performance tires and wheels the sky's the limit.
