Been trying to mount some 37" dirt tires on bead locks and I'm soooo F'n fed up. Cannot get the 'bead' to sit in the groove. I've done sand tires no problems, but the 37" BFG mud terrains are another animal. I even built a jig (out of 2x2 box tubing and threaded rod) to 'squeeze' the tires so I can start the beadlock bolts, but still cannot get the bead centered to start torquing the beadlock bolts. I'm in Nor CA so no shops want to touch bead locks. Mights try a Reno shop when I go home next week. My hands feel like hamburger.......
