x3 - Keep in mind that any unidirectional tire will wear unevenly due to the inability to rotate the tires. My last car wore Michelin Pilot Sports in 225-45-18s in the front and 245-45-18s in back. Those tires are unidirectional and due to the staggered size you couldn't rotate them front to back or side to side. Uneven tread wear was horrible on that tire. And at $225+ PER TIRE, replacing them every 20K miles was enough to break the bank on an all-too-regular basis.
x3 on the new Trail Grapplers too. That's a bad *** looking tread design (even better than the Terra Grapplers IMHO).
