A long time ago I saw an article about running an inner tube in side of tires to prevent bead loss. I do NOT want to run beadlocs or hummer rims. I did a search and read the post regarding the Swedish Tireloc system, and it reminded me of this article. I would love to get these but don't want to spend the $800 for a set. My question is, why can't you just run an inner tube inside your tire and skip the liner? It used to be the way all tires were. The article I read had two valves, one regular rim valve, and the tube valve stem that was theaded and would allow it to seal the rim up. They would run a certain amount in the tube (say 10 pounds) and the rest in the rim. Then they would just let all the rim pressure out when they went wheelin. Or at least that is how I remember it. Can someone shed some light on this for me?
