Which tire size?

[Afrancis]

Was just curious as to which tire size comes preloaded on the Gryphon? I got an 05 FX4 that comes stock with the 18", if I figured it up correctly my number should be 2559 (please correct me if Im wrong). The number that was preloaded was 2356, is that the 17"? Im mainly asking cause I want to be sure before I go making any changes. Thanks for any help with this. Also on a side note was just wondering if you guys got my HEX code I emailed to you a few days ago? Not trying to rush you, just dont want to have had my email lost in cyberspace, and end up finding out months down the road you never got it.
