I like the idea of the inflatable internal beadlocks...but I do see one drawback. Just as with my inner wheel lip and both of the Hummer wheel lips, you would have no damage protection. I have beat on my wheels pretty severely and the inner wheel lips show the abuse. The Rockstomper beadlocks I have welded on to lock the outer beads have taken plenty of abuse and have many scrapes and scars to show...but they DO protect the wheel lip very well.
Many of the folks who run the Hummer wheels end up adding some sort of lip protection- whether it be a ring of steel or a "rolled" piece of rod (or rebar) welded in...which then of course, adds to the overall weight.
