J C Whitney isn't the place to look for rims. I just put 225/45/17 on my 2002. Don't spend $ 230 for a Goodyear tire. For that price you can buy 2 Kuhmo or Yokahama tires witch are far better tires than the stock ( junk ) Goodyear's. Do a search on one of the search engines ( Yahoo or Google ) and put in custom wheels and you will find hundreds to choose from. If you live in pothole country don't go bigger than 17" because you can almost be sure you WILL bend one.
This will help keep the speedometer correct if you decide to change the size
