That is why I asked what type of wheel because the 03/04 Cobra wheels are 17x9's and can fit a 315 Nitto 555R.
A 9" wide wheel is a 9" wheel. As measured where the bead of the tire is installed. Unless their not actually giving exact specs or are measuring from a different location. In either case that will cause problems if that is happening.^^correct, just as reference my 19 x 9 OEM rims can only fit a 285 rear.
