You wanna stay light or don't mind some weight? If wanna stay light, get Trailready aluminum double beadlocks. If don't care about weight, TWF re-centered H1's or Stazworks.
Tires: Have you seen Interco is coming out with a new Mega SX offered in a 40" and a 50"? Supposed to be non-dot but tread depth is looking ridiculous. My brother runs 47" LTB's, and on his heavy rig (rockwells, lots of tube, realistically 6500 lbs, maybe a tad more) he is very happy with them. But I also heard a rumor that Interco might offer the 47" LTB in a sticky compound. That would be a game changer if you ask me as I think the dimensions of the 47" LTB is probably the best balanced big tire on the market. I also like the new Mickey Thompson 43" tire. Seems to be a good tire. And though the UDS Stickey tires have crazy curb appeal, I'm not convinced they will actually work worth a damn for normal trail wheeling use. Those huge side lugs will keep the rock bouncers happen with not as many flats cause their so tuff, but there is no way those side lugs are gonna flex worth a crap. I watched many videos on them, and you can tell they were designed specifically for the bouncers who close their eyes and mash the gas up a hill. So all they really care about is big, deep lugs with a crazy tuff carcass to keep from getting flats. Other than that, normal trial wheeling I could see wanting much more out of that tire. To each their own I guess
