Just FYI, TrailWorthyFab is now selling 17" beadlocks. Just like the Hummer wheels, except you can get modern tires.
$500 each wheel, including PVC insert. Free shipping on the first 10 orders, 5 left.
I don't know if the pressed centers are available for the 715, but their flat centers definitely are.
