Myself and a friend ran the original Tire Loc beadlocks, they are difficult to keep in place. With inner tubes, tthey can chafe and go flat. When inflated they work excellent. I thought that in deep Sierra snow the tube would push a little too much in the center. Imagine the runflats in the Hummer military wheels.
If you do use them, use copious amounts of talcum powder when assembling. It helps to lubricate and allow the inner stuff to stay straight.
My next set of locks is going to by USA6x6 doubles.
Currently, I am running poormans beadlocks. 10 in wheels on a 15.5 in tire.
Same here, 16.50's on a 9 inch wheel
