The wheels are Tech1 Black Rockcrawlers, available from www.4wheelparts.com .  They are the same as the American Racing 767's, minus the gay pride stripes.  I have the 16x8 with 4.25" backspacing.  They fit like a glove.  They did push the wheel outside the wheel well barely, as seen in the photos.  But this gave me plenty of clearance from the upper a-arm and frame.  I have not yet had the chance to test them out off-road, but as soon as I do you will know.
