Sure it is not the tire?
When I install tires on my Trail Readys, I put the rim bead lock wheel on a smaller wheel (daughter's 16, random 15" steelie, whatever). Spray the wheel down with soapy water. Put the tire over the outer lip of the wheel. Get the outer bead on the "shelf" evenly. Put the ring over the tire and ensure the holes align. Put 8 bolts in and just snug them to hold the ring in place (star pattern). Start the rest of the bolts. Hand tight only in a star (2 bolts at a time on each point on the star pattern) till the ring appears to have seated the bead properly and is starting to compress it. Then I start the in earnest 15-20-25 start pattern tightening. It usually takes about 4 cycles at each torque to seat the bolts.
In all honesty, I would put my money on the tires being the issue. How much weight are we talking here? My Toyo 40s took no more an 7 ounces on my Trail Ready beadlocks. The one creepy we checked on the machine wanted 18 and you could see how out of balance it was. Nitto and Toyo tires seem to be the "roundest". Rockers, anything bias, and MTRs have a reputation for requiring significant weight to balance out.
I have jeeps. I do shit to them.
