If your rig is more of a DD still I would stick with the BFGs AT KOs, I've ran those on my DD/trail rig and ran carnage Moab and a lot of CO trails and out side of deep nasty mud they have never let me down. I run 33x12.5r15s on my 01XJ and 235x75r15s on my same with my 89 toy truck. They never let me down they wear really well I get long mileage out of them as well. Procomp ats are ok not as aggressive as the BFGs and Revos and I always felt they wear down faster softer compounds so they don't last as many miles as they claim to. Revos are Bridgestone Duelers I like those as well on a more DD or light trails.
If your looking at more aggressive and no so great riding compared to an AT go with wrangler MTRs After the next transformation the XJ goes through I’m planning on sporting those next.
