You have one available? If you're just hunting, either 3rd or 4th gen Prius spare tire rims will work. The 3rd gen is a 16", and 4th gen a 17". My 2 cents, the (3rd gen) 16" with it's spec'd tire* is preferable, simply because the tire OD is closer to stock 195/65R15. The (4th gen) 17" with it's tire, is somewhat more undersized. Some links: 2016 Prius 2010 Prius 2008 Corolla * See owners manuals for the various gens, to get the tire spec. You can download pdf's from Toyota Tech Info.)
