I wrote a response on pro-t for you bud, but you can't forget than an 11.5" wide wheel, will measure 12.5" overall in width. You can't forget about the .50" bead on both sides. Also, backspace measurements are taken from the very edge of the wheel, so that .50" bead is included.
I was a little hard core over at PT, because I'm sick and tired of so called self proclaimed "experts" out there giving ill advice, so don't take it personally....
