yeah, it works, but some headache. First understand I change my own tire with these rims. I have done about 100 of these tires to date, and was a semi tire guy for 1 1/2 years, so I am fairly good at it.
The cut one was easier to go in and out of the tire for sure but more difficult to keep in position while assembling the rim.
When in use it held fine as a beadlock, but with the mt's, and bf Goodrich at's (35" hgh iirc) the center of the tread was cupping when down to 10 psi or more. It pinched the "knobbies" together and created a near solid line of rubber down the middle allowing slipping. My buddy there with a f250 tried them and did quite a burn out about 2" wide until the tire expanded from the centrifugal force and caught. My normal is 28 psi. In the sand it was about the same at 20 psi as it was 10 psi because of the cupping.
When I ran with the runflat as a whole unit, the center rubber supporting the tire in the middle stopped the cupping effect and worked better in the sand and rocks. Not at all what I expected, but it was the same results with Josh's Ford. My weight at the time was 7,200. No clue about his truck's weight.
I talked to a couple guys who are cutting out theirs, but they just didn't know the 2 strap trick for install. After I showed them that they said they would have ran them stock if they knew that in the first place.
I did decide after playing with the cut ones and the balance being harder to deal with than the unit as a whole, that I would just cut some from 1" aluminum or steel on a plasma table if I ever go with that set up. I know the antifreeze in the tire trick for balance, but cant do it with the ctis, if messes with the valves and those suckers are pricey. If you run regular valve stems the definitely ad the liquid.
