did you buy them used? is a wheel bent?
i use my 3/8's dewalt impact to tighten my bolts on my trail readys and they never leak. i go over them every now and again to make sure the rings still tight because its my DD.
take a water bottle, mix with some soap and spray around the ring, inside bead too!
find the bubbles, find your leak. if its the beadlock ring, tighten all the bolts again!
