What are you trying to ask? The only thing that matters is matching the tire diameter. The little 17 inch spare doesn't clear the sport brakes, so that's why the sport pkg comes with the 18 inch Enkei spare.

You can always run different size rims as long as you make sure the spare tire has a sidewall profile to match the diameter of your normal wheels and tires. That's why you can run an 18 inch enkei spare with 19 inch wheels - the enkei spare has a very large sidewall profile (70 vs 30/35) to make up for the rim size difference. Likewise, the 17 inch spare has a larger sidewall profile so that it works with the 18 inch base wheels.
