There are MORE tire choices in 15 inch tires than 16 inch.... This becomes even more true if we add power and need to add width. For example, once we get over 200 hp we often want to get 225mm wide tires on the ground. Our choices in 225/40/16 are now exactly ZERO....and we have just one choice in the tall 225/45/16. But in 15 inch 225/45/15 we have several choices...AND we have many more 15x8 choices to put those tires on (and 15x9 too).
Sorry, no polished five spoke in wide fitment because the design is generally heavier, that's why most of the choices you see are higher spoke count. Nearest we can get in the width for 225/45/15 is the Nickel finish 6ul 15x8 or our machine finish Konig Flatout
