I am thinking of jumping off of the BFG all terrain ship and boarding the Cooper Tires ship. I'm on my third set of BFG's. I've been reading good reviews of the Cooper AT-3 and that they perform better than the BFG A/T KO. But, the AT-3 doesn't have triple layer sidewall, which concerns me. I talked to a guy at work, who said he had friends that ran the AT-3's and they either got punctures or sliced up the sidewalls on rocks. So, I am considering either the S/T or the S/TMaxx and wondering how both of them perform compared to the AT-3.
