I'd say you had tire pressure or alignment issues. 24k on mine and I still have 70% tread depth on all 4. Rotate every oil change ( 5k or so), and run at 26-28 psi.

 

I've had my 35's for 2 years with over 13,000 mi and they are down to about 1/3 original tread. I DD mine everyday but it's only like 5 mi to work and drive it twice a day and down to San Diego at least once a month. Great tire in the rocks, I live in the desert so no mud, ok on the road. I think mine ride rough (load range E) but my JK only weighs 5000lbs and the roads out here are crap. I have punched a whole in two of them right in the side biters doing 15-30 mph on the desert floor on creosote bushes. Not a big deal, developed a slow leak each time and only took 1 plug for each. I have chunked them a little but not bad considering JV's terrain. I have notice that they seem sensative to temp changes of 20 degrees or more(happens often out here) they get a flat spot when cold and ride smoother warmed up. With the temp change I have to air them up or they start cupping in a day or two.

there very well could have been. it was lifted the cheap way, but none of them wore unevenly. i dont know if the extra 2000 pounds h2s carry could have done it the toyos i put on after wore much better. if i woulda known you guys were getting good life out of them i woulda considered em more
