I have Cooper Discoverer ST/Maxx tires on a non-jeep 4x4 I own. I currently have about 30,000 miles on them and based on the wear thus far I anticipate 40,000 miles before the tread is down to 4/32. They have performed well on multiple 1,000+ mile trips, offroading in the Cascades, Sierra Nevada Mountains, the Black Rock Desert, Death Valley, a 12-day cross-country overland trip in Oregon, and two trips to Moab. Although marketed as a commercial traction tire they can be accurately described as an aggressive AT tire with tough 3-ply sidewalls. I have nothing bad to say about them other than they tend to become more noisy as they wear, but that is a common phenomenon with any open void tire and can be kept in check by regular rotations at 4,000 mile intervals. You should be aware that nearly all (if not all) ST/Maxx tire sizes are E load rated so they will be a bit stiff for lighter jeeps, but that too can be addressed by not over inflating them. A set of ST/Maxx is usually much less expensive than a set of BFG AT tires, which makes them a great value considering how well they perform.
