Looking to buy a set of beadlock wheels to mount my mud tires to, and was looking at the system 3 sb-3 in a 6+1 offset to try to keep as close to factory width as possible. They only have a weight rating of 1000 lbs each. Is that sufficient? I see others using wheels with a rating of 1200 lbs (sti hd9), so those give an extra 800lbs of capacity. Any thoughts?
