For a little while, I ran Staun bead locks in 15x12 steel wheels with 44" TSL Boggers. I had terrible problems. They would run fine after the initial install as well as the 1st air down. (I would run 4-7 psi) The problem is that every time I aired back up, at least one tube would get pinched and pop. After 7 or 8 tubes in 2 months time, I sold them cheap and bought a set of Allied bead locks. An additional benefit of that actual bolt on bead locks was the strength of the outer wheel lip. The wheels that I was running the Stauns in got very bent up. With the Allieds, I had to replace a couple bolts, but the wheels held up.
