Them runflats are nothing but a solid chunck of rubber, similar to a soldi fork truck tire. They dont have anything to do with the beadlock. The beadlock is just a 2pc rim system that is used for field expediant repairs. Its easier to unbolt a rim, swap tires out, put it back together, throw a lil wind in it n keep rollin, vs having to carry a tire demounting machine or them tire spoons around for when u get a flat. I dont know bout you dub, but iv busted n remounted tires with just a tanker bar n 36" prybar n a lot of grease. It aint easy
